1、云上办公系统

1.1、介绍

云上办公系统是一套自动办公系统，系统主要包含：管理端和员工端

管理端包含：权限管理、审批管理、公众号菜单管理

员工端采用微信公众号操作，包含：办公审批、微信授权登录、消息推送等功能

项目服务器端架构：SpringBoot + MyBatisPlus + SpringSecurity + Redis + Activiti+ MySQL

前端架构：vue–admin–template + Node.js + Npm + Vue + ElementUI + Axios

1.2、核心技术

基础框架：SpringBoot
数据缓存：Redis
数据库：MySQL
权限控制：SpringSecurity
工作流引擎：Activiti
前端技术：vue–admin–template + Node.js + Npm + Vue + ElementUI + Axios
微信公众号：公众号菜单 + 微信授权登录 + 消息推送

1.3、开发环境说明

工具	版本
后台	SpringBoot 2.3.6 + MyBatisPlus 3.4.1
服务器	Tomcat 8.5.73
数据库	MySQL 8.0.27
Build Tools	Maven 3.8.5
前端	Vue + ElementUI + Node.js 14.15.0
开发工具	IDEA 2022.3
版本管理工具	Git

1.4、产品展示

后台

登录页

【系统管理】–【用户管理】

【系统管理】–【角色管理】

【系统管理】–【菜单管理】

【审批设置】–【审批类型】

【审批设置】–【审批模板】

【审批管理】–【审批列表】

【公众号菜单】–【菜单列表】

前台

正常的前台页面是在微信公众号上，我这里没有整合

http://localhost:9090/#/

审批页面

测试号的页面展示

1.5、 个人总结

我认为该项目对我来说主要的帮助有：

1、项目是前后端分离的，符合目前主流业务开发逻辑，作为后端程序员，复习前端Vue + ElementUI框架， 巩固练习使用前端的脚手架工程，学习使用前后端联调开发过程

2、项目中引入JWT加密token，用作用户登录身份校验，用 SpringSecurity 来做权限控制，涉及多表查询，是项目的重难点学习对象，也是对前面学习SpringSecurity的一个巩固

3、前端使用微信公众号来作为前端接入口，以前没有开发过，也是亮点。

4、引入 工作流引擎：Activiti 作为组件，第一次用，学习下

5、集成Swagger，方便进行接口API的统一测试

2、后端环境搭建

2.1、建库建表

db.sql

sql语句太多了，见文末的资料

2.2、创建Maven项目

本项目采用Maven聚合模块来管理工程

配置数据源、服务器端口号

application.yml

spring:
  application:
    name: service-oa
  profiles:
    active: dev

application–dev.yml

server:
  port: 8800
mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl # 查看日志
spring:
  datasource:
    type: com.zaxxer.hikari.HikariDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/guigu-oa?serverTimezone=GMT%2B8&useSSL=false&characterEncoding=utf-8
    username: root
    password: root

导入实体类

2.3、编写代码

启动类

package com.jerry.auth;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * ClassName: ServiceAuthApplication
 * Package: com.jerry.auth
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-02-28 22:03
 * @Version 1.0
 */

@SpringBootApplication
public class ServiceAuthApplication {
    public static void main(String[] args) {
        SpringApplication.run(ServiceAuthApplication.class, args);
    }
}

3、后端角色管理

3.1、查询所有角色

SysRoleMapper

package com.jerry.auth.mapper;

import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.jerry.model.system.SysRole;
import org.apache.ibatis.annotations.Mapper;

/**
 * ClassName: SysRoleMapper
 * Package: com.jerry.auth.mapper
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-02-28 22:05
 * @Version 1.0
 */

@Mapper
public interface SysRoleMapper extends BaseMapper<SysRole> {
}

SysRoleService

package com.jerry.auth.service;

import com.baomidou.mybatisplus.extension.service.IService;
import com.jerry.model.system.SysRole;

/**
 * ClassName: SysRoleService
 * Package: com.jerry.auth.service
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 9:12
 * @Version 1.0
 */


public interface SysRoleService extends IService<SysRole> {
}

SysRoleServiceImpl

package com.jerry.auth.service.impl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.jerry.auth.mapper.SysRoleMapper;
import com.jerry.auth.service.SysRoleService;
import com.jerry.model.system.SysRole;
import org.springframework.stereotype.Service;

/**
 * ClassName: SysRoleServiceImpl
 * Package: com.jerry.auth.service.impl
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 9:13
 * @Version 1.0
 */

@Service
public class SysRoleServiceImpl extends ServiceImpl<SysRoleMapper, SysRole> implements SysRoleService {
}

编写测试类

目的是：

• 测试数据源连接
• 复习下MyBatisPlus对数据库的CRUD

package com.jerry.auth;

import com.baomidou.mybatisplus.core.conditions.query.LambdaQueryWrapper;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.jerry.auth.mapper.SysRoleMapper;
import com.jerry.auth.service.SysRoleService;
import com.jerry.model.system.SysRole;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.Arrays;
import java.util.List;

/**
 * ClassName: TestMpDemo1
 * Package: com.jerry.auth
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-02-28 22:07
 * @Version 1.0
 */

@SpringBootTest
public class TestMpDemo1 {

    // MyBatisPlus 对 service 层和 dao 层都做了很好的封装，直接调对应的CRUD方法就行
    @Autowired
    private SysRoleMapper sysRoleMapper;

    @Autowired
    private SysRoleService sysRoleService;

    // 使用MP 封装的 service 来操作数据库，查询所有记录
    @Test
    public void getAllByService(){
        List<SysRole> list = sysRoleService.list();
        list.forEach(System.out::println);
    }

    // 使用MP 封装的 mapper查询所有记录
    @Test
    public void getAllByMapper(){
        List<SysRole> sysRoles = sysRoleMapper.selectList(null);
        sysRoles.forEach(System.out::println);
    }

    // 添加操作
    @Test
    public void insert(){
        SysRole sysRole = new SysRole();
        sysRole.setRoleName("角色管理员");
        sysRole.setRoleCode("role");
        sysRole.setDescription("角色管理员");
        int result = sysRoleMapper.insert(sysRole);

        System.out.println(result); //影响的行数
        System.out.println(sysRole.getId()); //id自动回填
    }

    // 修改操作
    @Test
    public void updateById(){
        // 根据id查询
        SysRole sysRole = sysRoleMapper.selectById(9);
        // 设置修改值
        sysRole.setRoleName("角色管理员1");
        // 调用方法实现最终修改
        int update = sysRoleMapper.updateById(sysRole);

        System.out.println("update = " + update); // 受影响的行数
    }

    // 根据id删除
    @Test
    public void deleteById(){
        int delete = sysRoleMapper.deleteById(9);

        System.out.println("delete = " + delete); // 受影响的行数
    }

    // 批量删除
    @Test
    public void deleteBatchByIds(){

//        int delete = sysRoleMapper.delete(null);

        // 或者下面这种写法
        int delete = sysRoleMapper.deleteBatchIds(Arrays.asList(1, 2));

        System.out.println("ids = " + delete); // 受影响的行数
    }

    // 条件查询
    @Test
    public void testQueryWrapper(){

//        QueryWrapper<SysRole> queryWrapper = new QueryWrapper<>();
//        queryWrapper.eq("role_name", "系统管理员");

        // 或者下面这种写法
        LambdaQueryWrapper<SysRole> queryWrapper = new LambdaQueryWrapper<>();
        queryWrapper.eq(SysRole::getRoleName,"系统管理员");

        List<SysRole> list = sysRoleMapper.selectList(queryWrapper);
        list.forEach(System.out::println);
    }
}

编写统一结果返回类

目的：定义好统一的返回状态码和返回结果信息

ResultCodeEnum

package com.jerry.common.result;

import lombok.Getter;

/**
 * ClassName: ResultCodeEnum
 * Package: com.jerry.common.result
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 9:50
 * @Version 1.0
 */

@Getter
public enum ResultCodeEnum {
    SUCCESS(200, "成功"),
    FAIL(201, "失败"),
    SERVICE_ERROR(2012, "服务异常"),
    DATA_ERROR(204, "数据异常"),

    LOGIN_AUTH(208, "未登陆"),
    PERMISSION(209, "没有权限");

    private Integer code;

    private String message;

    private ResultCodeEnum(Integer code, String message) {
        this.code = code;
        this.message = message;
    }
}

Result

package com.jerry.common.result;

import lombok.Data;

/**
 * ClassName: Result
 * Package: com.jerry.common.result
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 9:52
 * @Version 1.0
 */

@Data
public class Result<T> {
    private Integer code; // 状态码
    private String message; // 返回信息
    private T data; // 统一返回的结果数据

    /**
     * 封装返回数据
     * @param body
     * @param resultCodeEnum
     * @return
     * @param <T>
     */
    public static <T> Result<T> build(T body, ResultCodeEnum resultCodeEnum) {
        Result<T> result = new Result<>();

        // 封装数据
        if (body!=null){
            result.setData(body);
        }

        // 状态码
        result.setCode(resultCodeEnum.getCode());
        //返回信息
        result.setMessage(resultCodeEnum.getMessage());
        return result;
    }

    // 构造私有化 外部不能new
    private Result(){}

    // 成功 空结果
    public static <T>Result<T> ok(){
        return build(null,ResultCodeEnum.SUCCESS);
    }

    /**
     * 成功 返回有数据的结果
     * @param data
     * @return
     * @param <T>
     */
    public static <T>Result<T> ok(T data){
        return build(data,ResultCodeEnum.SUCCESS);
    }

    // 失败
    public static <T>Result<T> fail(){
        return build(null,ResultCodeEnum.FAIL);
    }

    /**
     * 失败  返回有数据的结果
     * @param data
     * @return
     * @param <T>
     */
    public static <T>Result<T> fail(T data){
        return build(data,ResultCodeEnum.FAIL);
    }

    public Result<T> message(String msg){
        this.setMessage(msg);
        return this;
    }

    public Result<T> code(Integer code){
        this.setCode(code);
        return this;
    }
}

SysRoleController

package com.jerry.auth.controller;

import com.jerry.auth.service.SysRoleService;
import com.jerry.common.result.Result;
import com.jerry.model.system.SysRole;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;

/**
 * ClassName: SysRoleController
 * Package: com.jerry.auth.controller
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 9:38
 * @Version 1.0
 */

@RestController
@RequestMapping("/admin/system/sysRole")
public class SysRoleController {
    @Autowired
    private SysRoleService sysRoleService;

    // http://localhost:8800/admin/system/sysRole/getAll
    // 测试查询所有的角色
//    @GetMapping("/getAll")
//    private List<SysRole> getAll(){
//        List<SysRole> list = sysRoleService.list();
//        return list;
//    }

    /**
     * 统一返回数据结果
     * @return
     */
    @GetMapping("/getAll")
    private Result getAll(){
        List<SysRole> list = sysRoleService.list();
        return Result.ok(list);
    }

}

测试

http://localhost:8800/admin/system/sysRole/getAll

3.2、集成knife4j

文档地址：https://doc.xiaominfo.com/

knife4j是为Java MVC框架集成Swagger生成Api文档的增强解决方案。

Swagger介绍

前后端分离开发模式中，api文档是最好的沟通方式。

Swagger 是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。

1、及时性 (接口变更后，能够及时准确地通知相关前后端开发人员)

2、规范性 (并且保证接口的规范性，如接口的地址，请求方式，参数及响应格式和错误信息)

3、一致性 (接口信息一致，不会出现因开发人员拿到的文档版本不一致，而出现分歧)

4、可测性 (直接在接口文档上进行测试，以方便理解业务)

目的

• 用来生成接口的API文档

• 方便后端Java程序员进行接口测试

使用步骤

添加依赖

service-uitl.pom

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
</dependency>

添加knife4j配置类

package com.jerry.common.config.knife4j;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.schema.ModelRef;

 */

/**
 * knife4j配置信息
 */
@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfig {

    @Bean
    public Docket adminApiConfig(){
        List<Parameter> pars = new ArrayList<>();
        ParameterBuilder tokenPar = new ParameterBuilder();
        tokenPar.name("token")
                .description("用户token")
                .defaultValue("")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                .required(false)
                .build();
        pars.add(tokenPar.build());
        //添加head参数end

        Docket adminApi = new Docket(DocumentationType.SWAGGER_2)
                .groupName("adminApi")
                .apiInfo(adminApiInfo())
                .select()
                //只显示admin路径下的页面
                .apis(RequestHandlerSelectors.basePackage("com.jerry"))
                .paths(PathSelectors.regex("/admin/.*"))
                .build()
                .globalOperationParameters(pars);
        return adminApi;
    }

    private ApiInfo adminApiInfo(){

        return new ApiInfoBuilder()
                .title("后台管理系统-API文档")
                .description("本文档描述了后台管理系统微服务接口定义")
                .version("1.0")
                .contact(new Contact("jerry", "https://jerry-jy.co", "jinyang9248@163.com"))
                .build();
    }

}

Controller层添加注解

• 类上加@Api(tags = "角色管理接口")
• 方法上加@ApiOperation("查询所有角色")

测试

http://localhost:8800/doc.html

3.3、分页查询所有角色

service-util模块下创建 MybatisPlusConfig

MybatisPlusConfig

package com.jerry.common.config.mp;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.autoconfigure.ConfigurationCustomizer;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * ClassName: MybatisPlusConfig
 * Package: com.jerry.common.config.mp
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 11:17
 * @Version 1.0
 */

@Configuration
@MapperScan("com.jerry.auth.mapper")
public class MybatisPlusConfig {

    /**
     * 新的分页插件,一缓和二缓遵循mybatis的规则,需要设置 MybatisConfiguration#useDeprecatedExecutor = false 避免缓存出现问题(该属性会在旧插件移除后一同移除)
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
        return interceptor;
    }

    @Bean
    public ConfigurationCustomizer configurationCustomizer() {
        return configuration -> configuration.setUseDeprecatedExecutor(false);
    }
}

主启动类上添加包扫描

SysRoleController

    /**
     * 条件分页查询
     *
     * @param page           当前页
     * @param pageSize       分页大小
     * @param sysRoleQueryVo 条件查询对象
     * @return
     */
    @ApiOperation("条件分页查询")
    @GetMapping("{page}/{pageSize}")
    private Result page(@PathVariable int page, @PathVariable int pageSize, SysRoleQueryVo sysRoleQueryVo) {

        // 1、创建 page 对象， 传递分页查询的参数
        Page<SysRole> sysRolePage = new Page<>(page, pageSize);

        // 2、构造分页查询条件, 判断条件是否为空，不为空进行封装
        LambdaQueryWrapper<SysRole> lambdaQueryWrapper = new LambdaQueryWrapper<>();
        String roleName = sysRoleQueryVo.getRoleName();
        if (!StringUtils.isEmpty(roleName)) {
            // 封装
            lambdaQueryWrapper.like(SysRole::getRoleName,roleName);
        }

        // 3、调用方法实现分页查询
       sysRoleService.page(sysRolePage, lambdaQueryWrapper);
        return Result.ok(sysRolePage);
    }

测试

3.4、添加/修改/删除角色

    /**
     * 添加角色
     * @param sysRole
     * @return
     */
    @ApiOperation("添加角色")
    @PostMapping("/save")
    public Result save(@RequestBody SysRole sysRole) {
        // 调用 service 方法
        boolean is_success = sysRoleService.save(sysRole);
        if (is_success) {
            return Result.ok();
        } else {
            return Result.fail();
        }
    }

    /**
     * 根据 id 修改角色
     * @param id
     * @return
     */
    @ApiOperation("根据 id 查询角色")
    @GetMapping("/get/{id}")
    public Result get(@PathVariable long id){
        SysRole sysRole = sysRoleService.getById(id);
        return Result.ok(sysRole);
    }

    /**
     * 修改角色
     * @param sysRole
     * @return
     */
    @ApiOperation("修改角色")
    @PutMapping("/update")
    public Result update(@RequestBody SysRole sysRole) {
        // 调用 service 方法
        boolean is_success = sysRoleService.updateById(sysRole);
        if (is_success) {
            return Result.ok();
        } else {
            return Result.fail();
        }
    }

    /**
     * 根据 id 删除
     * @param id
     * @return
     */
    @ApiOperation("根据 id 删除")
    @DeleteMapping("delete/{id}")
    public Result deleteById(@PathVariable long id){
        boolean is_success = sysRoleService.removeById(id);

        if (is_success) {
            return Result.ok();
        } else {
            return Result.fail();
        }
    }

    /**
     * 批量删除
     * 说明：
     *      Java 中的对象会转化为Json对象
     *      Java 中的List集合会转化为数组
     * @param ids
     * @return
     */
    @ApiOperation("批量删除")
    @DeleteMapping("/ids")
    public Result deleteByIds(@RequestBody List<Long> ids){

        boolean is_success = sysRoleService.removeByIds(ids);

        if (is_success) {
            return Result.ok();
        } else {
            return Result.fail();
        }
    }

测试

配置日期时间格式

application-dev.yml添加以下内容

  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

4、统一异常处理

异常处理的思路流程

4.1、全局异常处理

4.2、特定异常处理

4.3、自定义异常处理

service-util 模块下

GlobalExceptionHandler

package com.jerry.common.config.exception;

import com.jerry.common.result.Result;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * ClassName: GlobalExceptionHandler
 * Package: com.jerry.common.config.exception
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 15:48
 * @Version 1.0
 */
@ControllerAdvice
public class GlobalExceptionHandler {

    /**
     * 全局异常处理 执行的方法
     * @return
     */
    @ExceptionHandler(Exception.class)
    @ResponseBody
    public Result error(Exception e){
        e.printStackTrace();
        return Result.fail().message("执行全局处理异常...");
    }

    /**
     * 特定异常处理
     * @param e
     * @return
     */
    @ExceptionHandler(ArithmeticException.class)
    @ResponseBody
    public Result error(ArithmeticException e){
        e.printStackTrace();
        return Result.fail().message("执行特定处理异常...");
    }

    /**
     * 自定义异常处理
     * @param e
     * @return
     */
    @ExceptionHandler(GuiguException.class)
    @ResponseBody
    public Result error(GuiguException e){
        e.printStackTrace();
        return Result.fail().code(e.getCode()).message(e.getMsg());
    }
}

GuiguException

package com.jerry.common.config.exception;

import com.jerry.common.result.ResultCodeEnum;
import lombok.Data;

/**
 * ClassName: GuiguException
 * Package: com.jerry.common.config.exception
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 15:59
 * @Version 1.0
 */
@Data
public class GuiguException extends RuntimeException {

    private Integer code;

    private String msg;

    /**
     * 通过状态码和错误消息创建异常对象
     * @param code
     * @param msg
     */
    public GuiguException(Integer code, String msg) {
        super(msg);
        this.code = code;
        this.msg = msg;
    }

    /**
     * 接收枚举类型对象
     * @param resultCodeEnum
     */
    public GuiguException(ResultCodeEnum resultCodeEnum) {
        super(resultCodeEnum.getMessage());
        this.code = resultCodeEnum.getCode();
        this.msg = resultCodeEnum.getMessage();
    }

    @Override
    public String toString() {
        return "GuiguException{" +
                "code=" + code +
                ", msg='" + msg + ''' +
                '}';
    }
}

5、前端环境搭建

安装脚手架工程

前端用的脚手架工程是：vue-element-admin

https://panjiachen.github.io/vue-element-admin-site/#/

# clone the project
git clone https://github.com/PanJiaChen/vue-element-admin.git

# install dependency
npm install

# develop
npm run dev

http://localhost:9528/#/dashboard

前后联调的流程

修改前端的IP地址

    // before: require('./mock/mock-server.js')
    proxy: {
      '/dev-api': { // 匹配所有以 '/dev-api'开头的请求路径
        target: 'http://localhost:8800',
        changeOrigin: true, // 支持跨域
        pathRewrite: { // 重写路径: 去掉路径中开头的'/dev-api'
          '^/dev-api': ''
        }
      }
    }

编写后台登录/登出的请求

IndexController

package com.jerry.auth.controller;

import com.jerry.common.result.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;
import java.util.Objects;

/**
 * ClassName: IndexController
 * Package: com.jerry.auth.controller
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-01 18:15
 * @Version 1.0
 */
@Api(tags = "后台登录管理")
@RestController
@RequestMapping("/admin/system/index")
public class IndexController {

    /**
     * login
     * @return
     */
    @ApiOperation("登录")
    @PostMapping("/login")
    public Result login(){
        // {"code":200,"data":{"token":"admin-token"}}
        HashMap<String, Object> map = new HashMap<>();
        map.put("token","admin-token");
        return Result.ok(map);
    }

    /**
     * info
     * @return
     */
    @GetMapping("/info")
    public Result info(){
        Map<String, Object> map = new HashMap<>();
        map.put("roles","[admin]");
        map.put("name","admin");
        map.put("avatar","https://oss.aliyuncs.com/aliyun_id_photo_bucket/default_handsome.jpg");
        return Result.ok(map);
    }

    /**
     * logout
     * @return
     */
    @ApiOperation("登出")
    @PostMapping("/logout")
    public Result logout(){
        return Result.ok();
    }
}

修改前端的跳转地址

修改响应状态码

测试

重启前端、后端项目，可以发现请求头信息已经做了跳转、转发

6、前端角色管理

6.1、角色列表

修改路由

重新定义constantRoutes

  {
    path: '/system',
    component: Layout,
    meta: {
      title: '系统管理',
      icon: 'el-icon-s-tools'
    },
    alwaysShow: true,
    children: [
      {
        path: 'sysRole',
        component: () => import('@/views/system/sysRole/list'),
        meta: {
          title: '角色管理',
          icon: 'el-icon-s-help'
        },
      }
    ]
  },

创建角色页面

<template>
<div class="app-container">

    <!--查询表单-->
    <div class="search-div">
      <el-form label-width="70px" size="small">
        <el-row>
          <el-col :span="24">
            <el-form-item label="角色名称">
              <el-input style="width: 100%" v-model="searchObj.roleName" placeholder="角色名称"></el-input>
            </el-form-item>
          </el-col>
        </el-row>
        <el-row style="display:flex">
          <el-button type="primary" icon="el-icon-search" size="mini" :loading="loading" @click="fetchData()">搜索</el-button>
          <el-button icon="el-icon-refresh" size="mini" @click="resetData">重置</el-button>
        </el-row>
      </el-form>
    </div>

    <!-- 表格 -->
    <el-table
      v-loading="listLoading"
      :data="list"
      stripe
      border
      style="width: 100%;margin-top: 10px;"
      @selection-change="handleSelectionChange">

      <el-table-column type="selection"/>

      <el-table-column
        label="序号"
        width="70"
        align="center">
        <template slot-scope="scope">
          {{ (page - 1) * limit + scope.$index + 1 }}
        </template>
      </el-table-column>

      <el-table-column prop="roleName" label="角色名称" />
      <el-table-column prop="roleCode" label="角色编码" />
      <el-table-column prop="createTime" label="创建时间" width="160"/>
      <el-table-column label="操作" width="200" align="center">
        <template slot-scope="scope">
          <el-button type="primary" icon="el-icon-edit" size="mini" @click="edit(scope.row.id)" title="修改"/>
          <el-button type="danger" icon="el-icon-delete" size="mini" @click="removeDataById(scope.row.id)" title="删除"/>
        </template>
      </el-table-column>
    </el-table>

    <!-- 分页组件 -->
    <el-pagination
        :current-page="page"
        :total="total"
        :page-size="limit"
        style="padding: 30px 0; text-align: center;"
        layout="total, prev, pager, next, jumper"
        @current-change="fetchData"
    />
  </div>
</template>

<script>
import api from '@/api/system/sysRole'
export default {
  // 定义数据模型
  // 定义数据模型
  data() {
    return {
      list: [], // 列表
      total: 0, // 总记录数
      page: 1, // 页码
      limit: 2, // 每页记录数
      searchObj: {}, // 查询条件
      multipleSelection: []// 批量删除选中的记录列表
    }
  },
  // 页面渲染成功后获取数据
  created() {
    this.fetchData()
  },
  // 定义方法
  methods: {
    fetchData(current=1) {
      this.page = current
      // 调用api
      api.getPageList(this.page, this.limit, this.searchObj).then(response => {
        this.list = response.data.records
        this.total = response.data.total
      })
    },
  }
}
</script>

定义角色管理相关的API请求函数

/*
角色管理相关的API请求函数
*/
import request from '@/utils/request'

const api_name = '/admin/system/sysRole'

export default {

  /*
  获取角色分页列表(带搜索)
  */
  getPageList(page, limit, searchObj) {
    return request({
      url: `${api_name}/${page}/${limit}`,
      method: 'get',
      // 如果是普通对象参数写法，params:对象参数名
      // 如果是使用json格式传递，data:对象参数名
      params: searchObj
    })
  }
}

测试

重新启动前端工程

http://localhost:9528/?#/system/sysRole

6.2、角色删除

sysRole.js

  /**
   * 角色删除
   * @param {*} id 
   * @returns 
   */
  removeById(id) {
    return request({
      url: `${api_name}/delete/${id}`,
      method: 'delete'
    })
  }

list.vue

    // 根据id删除数据
    removeDataById(id) {
        // debugger
        this.$confirm('此操作将永久删除该记录, 是否继续?', '提示', {
            confirmButtonText: '确定',
            cancelButtonText: '取消',
            type: 'warning'
        }).then(() => { // promise
            // 点击确定，远程调用ajax
            return api.removeById(id)
        }).then((response) => {
            // 刷新页面
            this.fetchData(this.page)
            // 提示信息
            this.$message.success(response.message || '删除成功')
        })
    }

6.3、角色添加

6.4、角色修改与数据回显

6.5、批量删除

前端CRUD完整代码

注意点：

前端中的url请求路径要和后端的@DeleteMapping，@PutMapping，@PostMapping，@GetMapping路径一致

sysRole.js

/*
角色管理相关的API请求函数
*/
import request from '@/utils/request'

const api_name = '/admin/system/sysRole'

export default {

 /**
  * 获取角色分页列表(带搜索)
  * @param {*} page 
  * @param {*} limit 
  * @param {*} searchObj 
  * @returns 
  */
  getPageList(page, limit, searchObj) {
    return request({
      url: `${api_name}/${page}/${limit}`,
      method: 'get',
      // 如果是普通对象参数写法，params:对象参数名
      // 如果是使用json格式传递，data:对象参数名
      params: searchObj
    })
  },

  /**
   * 角色删除
   * @param {*} id 
   * @returns 
   */
  removeById(id) {
    return request({
      url: `${api_name}/delete/${id}`,
      method: 'delete'
    })
  },

  /**
   * 角色添加
   * @param {*} role 
   * @returns 
   */
  save(role) {
    return request({
      url: `${api_name}/save`,
      method: 'post',
      data: role
    })
  },

  // 回显要修改的id信息
  getById(id) {
    return request({
      url: `${api_name}/get/${id}`,
      method: 'get'
    })
  },
  
  // 修改
  updateById(role) {
    return request({
      url: `${api_name}/update`,
      method: 'put',
      data: role
    })
  },

  // 批量删除
  batchRemove(idList) {
    return request({
      url: `${api_name}/ids`,
      method: `delete`,
      data: idList
    })
  }


}

添加路由

      {

          title: '用户管理',
          icon: 'el-icon-s-custom'
        },
      },

定义API接口

import request from '@/utils/request'

const api_name = '/admin/system/sysUser'

export default {

  getPageList(page, limit, searchObj) {
    return request({
      url: `${api_name}/${page}/${limit}`,

7.2、用户管理分配角色

需求分析

• 一个用户对应多个角色

• 一个角色可以有多个用户

多对多的关系

接口分析

• 1、进入分配页面：获取已分配角色与全部角色，进行页面展示

• 2、保存分配角色：删除之前分配的角色和保存现在分配的角色

编写代码

代码是写在service-oa类中的

SysUserRoleMapper

public interface SysUserRoleMapper extends BaseMapper<SysUserRole> {
}

SysUserRoleService

public interface SysUserRoleService extends IService<SysUserRole> {
}

SysUserRoleServiceImpl

@Service
public class SysUserRoleServiceImpl extends ServiceImpl<SysUserRoleMapper, SysUserRole> implements SysUserRoleService {

SysRoleController

    // 1、查询所有角色 和 当前用户所属角色

前端展示

7.3、修改用户状态

需求分析

用户状态：状态（1：正常 0：停用），当用户状态为正常时，可以访问后台系统，当用户状态停用后，不可以登录后台系统

编写代码

SysRoleController

    @ApiOperation(value = "更新状态")
    @GetMapping("/updateStatus/{id}/{status}")
    public Result updateStatus(@PathVariable Long id, @PathVariable Integer status){
        sysUserService.updateStatus(id, status);
        return Result.ok();
    }

SysUserService

public interface SysUserService extends IService<SysUser> {

    // 更新状态
    void updateStatus(Long id, Integer status);
}

SysUserServiceImpl

@Service
@Slf4j
public class SysUserServiceImpl extends ServiceImpl<SysUserMapper, SysUser> implements SysUserService {

    // 更新状态
    @Override
    @Transactional
    public void updateStatus(Long id, Integer status) {
        // 根据用户 userid 查询用户对象
        SysUser sysUser = baseMapper.selectById(id);

        // 设置修改状态
        if (status == 0 || status == 1) {
            sysUser.setStatus(status);
        } else {
            log.info("数值不合法");
        }

        // 调用方法进行修改
        baseMapper.updateById(sysUser);
    }
}

整合前端

定义前端路由

src/api/system/sysUser.js

updateStatus(id, status) {
  return request({
    url: `${api_name}/updateStatus/${id}/${status}`,
    method: 'get'
  })
}

src/api/system/sysRole.js

getRoles(adminId) {
  return request({
    url: `${api_name}/toAssign/${adminId}`,
    method: 'get'
  })
},

assignRoles(assginRoleVo) {
  return request({
    url: `${api_name}/doAssign`,
    method: 'post',
    data: assginRoleVo
  })
}

修改前端页面

9、权限管理（重难点）

9.1、用户登录权限管理

需求分析

引入JWT

• JWT是JSON Web Token的缩写

• 一般被用来在身份提供者和服务提供者间传递被认证的用户身份信息，以便于从资源服务器获取资源。比如用在用户登录上

• 官网：https://jwt.io/

• 最重要的作用就是对 token信息的防伪作用。

• 由三个部分组成：JWT头、有效载荷、签名哈希

• base64url算法编码得到JWT

common-util

        <dependency>
            <groupId>io.jsonwebtoken</groupId>

                .setExpiration(new Date(System.currentTimeMillis() + tokenExpiration))
                .claim("userId", userId)
                .claim("username", username)

                    '9', 'a', 'b', 'c', 'd', 'e', 'f' };
            byte[] bytes = strSrc.getBytes();
            MessageDigest md = MessageDigest.getInstance("MD5");
            md.update(bytes);
            bytes = md.digest();
            int j = bytes.length;
            char[] chars = new char[j * 2];
            int k = 0;
            for (int i = 0; i < bytes.length; i++) {
                byte b = bytes[i];
                chars[k++] = hexChars[b >>> 4 & 0xf];
                chars[k++] = hexChars[b & 0xf];
            }
            return new String(chars);
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
            throw new RuntimeException("MD5加密出错！！+" + e);
        }
    }

    public static void main(String[] args) {
        System.out.println(MD5.encrypt("111111"));
    }
}

接口测试

登录接口测试

info接口测试

我这里没有报错，如果出现以下的报错信息

解决思路是：

1、在pom.xml添加

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.yml</include>
                    <include>**/*.properties</include>
                    <include>**/*.xml</include>
                </includes>
                <filtering>false</filtering>
            </resource>
            <resource>

                <filtering>false</filtering>
            </resource>
        </resources>
    </build>

2、application-dev.yml添加

mybatis-plus:
  mapper-locations: classpath:com/atguigu/auth/mapper/xml/*.xml

整合前端

从这部分开始，整合前端不在写了，比较麻烦，直接复用现有的

给李四分配没有添加的权限

9.2、用户认证

整合SpringSecurity

本项目采用 Spring-Security 来做用户认证和权限控制，也可以采用 Shiro

新建一个spring-security的module

引入依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        <groupId>com.jerry</groupId>
        <artifactId>common</artifactId>
        <version>1.0</version>
    </parent>
    <artifactId>spring-security</artifactId>

    <dependencies>
        <dependency>
            <groupId>com.jerry</groupId>
            <artifactId>common-util</artifactId>
            <version>1.0</version>
        </dependency>
        <!-- Spring Security依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>

            <scope>provided </scope>
        </dependency>
    </dependencies>

</project>

添加配置类

package com.jerry.security.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

/**
 * ClassName: WebSecurityConfig
 * Package: com.jerry.security.config
 * Description:
 *
 * @Author jerry_jy
 * @Create 2023-03-03 13:44
 * @Version 1.0
 */

@Configuration
@EnableWebSecurity  //@EnableWebSecurity是开启SpringSecurity的默认行为
public class WebSecurityConfig {
}

在 service-oa 中引入spring-security的module

测试

在浏览器访问：http://localhost:8800/admin/system/sysRole/getAll

这时候想绕过登录页是不能的，后台服务经过会spring-security做了用户认证，提示用户需要先登录

默认的登录名是：user

密码是IDEA中生成的一串随机字符，每次都不一样

用户认证

流程分析

自定义组件的编写

操作spring-securitymodule

自定义加密器PasswordEncoder

@Component
public class CustomMd5PasswordEncoder implements PasswordEncoder {
    public String encode(CharSequence rawPassword) {
        return MD5.encrypt(rawPassword.toString());
    }

    public boolean matches(CharSequence rawPassword, String encodedPassword) {
        return encodedPassword.equals(MD5.encrypt(rawPassword.toString()));
    }
}

自定义用户对象UserDetails

public class CustomUser extends User {
    /**
     * 我们自己的用户实体对象，要调取用户信息时直接获取这个实体对象。（这里我就不写get/set方法了）
     */
    private SysUser sysUser;

    public CustomUser(SysUser sysUser, Collection<? extends GrantedAuthority> authorities) {
        super(sysUser.getUsername(), sysUser.getPassword(), authorities);
        this.sysUser = sysUser;
    }

    public SysUser getSysUser() {
        return sysUser;
    }

    public void setSysUser(SysUser sysUser) {
        this.sysUser = sysUser;
    }
}

UserDetailsService

public interface UserDetailsService {
    /**
     * 根据用户名获取用户对象（获取不到直接抛异常）
     */
    UserDetails loadUserByUsername(String username) throws UsernameNotFoundException;
}

操作service-oamodule

UserDetailsServiceImpl

@Service
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private SysUserService sysUserService;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

        // 根据用户名查询
        SysUser sysUser = sysUserService.getUserByUserName(username);
        if(null == sysUser) {
            throw new UsernameNotFoundException("用户名不存在！");
        }

        if(sysUser.getStatus().intValue() == 0) {
            throw new RuntimeException("账号已停用");
        }
        return new CustomUser(sysUser, Collections.emptyList());
    }
}

SysUserService

    SysUser getUserByUserName(String username);

SysUserServiceImpl

    // 根据用户名查询
    @Override
    public SysUser getUserByUserName(String username) {
        LambdaQueryWrapper<SysUser> queryWrapper = new LambdaQueryWrapper<>();
        queryWrapper.eq(SysUser::getUsername,username);

        SysUser sysUser = baseMapper.selectOne(queryWrapper);
        return sysUser;
    }

自定义用户认证接口

        CustomUser customUser = (CustomUser) auth.getPrincipal();

        // 生成token
        String token = JwtHelper.createToken(customUser.getSysUser().getId(), customUser.getSysUser().getUsername());

        // 返回
        Map<String, Object> map = new HashMap<>();

        ResponseUtil.out(response, Result.ok(map));
    }

    // 认证失败调用的方法

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

认证解析token

因为用户登录状态在token中存储在客户端，所以每次请求接口请求头携带token， 后台通过自定义token过滤器拦截解析token完成认证并填充用户信息实体

package com.jerry.security.filter;

import com.jerry.common.jwt.JwtHelper;
import com.jerry.common.result.ResponseUtil;
import com.jerry.common.result.Result;
import com.jerry.common.result.ResultCodeEnum;

public class TokenAuthenticationFilter extends OncePerRequestFilter {
    public TokenAuthenticationFilter() {
    }
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException, IOException {

        logger.info("uri:"+request.getRequestURI());
        //如果是登录接口，直接放行
        if("/admin/system/index/login".equals(request.getRequestURI())) {
            chain.doFilter(request, response);
            return;
        }

        UsernamePasswordAuthenticationToken authentication = getAuthentication(request);
        if(null != authentication) {
            SecurityContextHolder.getContext().setAuthentication(authentication);
            chain.doFilter(request, response);
        } else {
            ResponseUtil.out(response, Result.build(null, ResultCodeEnum.PERMISSION));
        }
    }

    private UsernamePasswordAuthenticationToken getAuthentication(HttpServletRequest request) {
        // token置于header里
        String token = request.getHeader("token");
        logger.info("token:"+token);
        if (!StringUtils.isEmpty(token)) {
            String username = JwtHelper.getUsername(token);

            }
        }
        return null;
    }
}

@Configuration
@EnableWebSecurity  //@EnableWebSecurity是开启SpringSecurity的默认行为

    @Autowired
    private UserDetailsService userDetailsService; // 装载的是 org.springframework.security.core.userdetails.UserDetailsService;

}

测试

说明：

1、我们是前后端分离项目，使用jwt生成token ，即用户状态保存在客户端中，前后端交互通过api接口 无session生成，所以我们不需要配置formLogin，session禁用

2、在浏览器访问：http://localhost:8800/admin/system/sysRole/getAll

9.3、用户权限控制

流程分析

修改代码

修改UserDetailsServiceImpl中的loadUserByUsername

        // 根据 user_id 查询用户操作权限数据
        List<String> userPermsList = sysMenuService.findUserPermsByUserId(sysUser.getId());
        // 创建list集合，封装最终权限数据
        List<SimpleGrantedAuthority> authList =  new ArrayList<>();
        // 遍历 authList
        for (String perms : userPermsList) {
            authList.add(new SimpleGrantedAuthority(perms.trim()));
        }

        return new CustomUser(sysUser, authList);

spring-security模块配置redis

添加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

修改TokenLoginFilter

修改TokenAuthenticationFilter

修改WebSecurityConfig类

配置类添加注解：

开启基于方法的安全认证机制，也就是说在web层的controller启用注解机制的安全确认

service-oa模块添加redis配置

application-dev.yml配文件

spring:
  redis:
    host: localhost
    port: 6379
    database: 0
    timeout: 1800000
    password:
    jedis:
      pool:
        max-active: 20 #最大连接数
        max-wait: -1    #最大阻塞等待时间(负数表示没限制)
        max-idle: 5    #最大空闲
        min-idle: 0     #最小空闲

控制controller层接口权限

Spring Security默认是禁用注解的，要想开启注解，需要在继承WebSecurityConfigurerAdapter的类上加@EnableGlobalMethodSecurity注解，来判断用户对某个控制层的方法是否具有访问权限

    @PreAuthorize("hasAuthority('bnt.sysRole.list')")

    @PreAuthorize("hasAuthority('bnt.sysRole.add')")

    @PreAuthorize("hasAuthority('bnt.sysRole.list')")

    @PreAuthorize("hasAuthority('bnt.sysRole.update')")

    @PreAuthorize("hasAuthority('bnt.sysRole.remove')")

异常处理

在service-util模块引入依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
            <scope>provided</scope>
        </dependency>

AccessDeniedException需要引入依赖，Spring Security对应的异常

    /**
     * spring security异常
     * @param e
     * @return
     */
    @ExceptionHandler(AccessDeniedException.class)
    @ResponseBody
    public Result error(AccessDeniedException e) throws AccessDeniedException {
        return Result.build(null, ResultCodeEnum.PERMISSION);
    }

10、Activiti

10.1、Activiti流程操作

配置Activiti

引入Activiti依赖

在service-oa中

<!--引入activiti的springboot启动器 -->
<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-spring-boot-starter</artifactId>
    <version>7.1.0.M6</version>
    <exclusions>
        <exclusion>
            <artifactId>mybatis</artifactId>
            <groupId>org.mybatis</groupId>
        </exclusion>
    </exclusions>
</dependency>

添加配置

在application-dev.yml中添加如下配置

spring:    
	activiti:
      #    false:默认，数据库表不变，但是如果版本不对或者缺失表会抛出异常（生产使用）
      #    true:表不存在，自动创建（开发使用）
      #    create_drop: 启动时创建，关闭时删除表（测试使用）
      #    drop_create: 启动时删除表,在创建表 （不需要手动关闭引擎）
      database-schema-update: true
      #监测历史表是否存在，activities7默认不开启历史表
      db-history-used: true
      #none：不保存任何历史数据，流程中这是最高效的
      #activity：只保存流程实例和流程行为
      #audit：除了activity，还保存全部的流程任务以及其属性，audit为history默认值
      #full：除了audit、还保存其他全部流程相关的细节数据，包括一些流程参数
      history-level: full
      #校验流程文件，默认校验resources下的process 文件夹的流程文件
      check-process-definitions: true

重启项目

会自己创建数据表

使用activiti插件

下载activiti-explorer

官网下载：https://www.activiti.org/get-started

解压部署

把解压出来的activiti-explorer.war放在Tomcat的webapps下

启动Tomcat服务器

10.3、网关

网关用来控制流程的流向，通常会和流程变量一起使用。

排他网关

• 排他网关：只有一条路径会被选择

当你的流程出现这样的场景：请假申请，两天以内，部门经理审批流程就结束了，两天以上需要总经理直接审批，这个时候就需要排他网关

并行网关

• 并（平）行网关：所有路径会被同时选择

当出现这样的场景：请假申请开始，需要部门经理和总经理都审批，两者没有前后需要两个人全部审批才能进入下个节点人事审批。这个时候就需要并行网关

与排他网关的主要区别是，并行网关不会解析条件。 即使顺序流中定义了条件，也会被忽略。

包含网关

包容网关：可以同时执行多条线路，也可以在网关上设置条件，可以看做是排他网关和并行网关的结合体。
当出现这样的场景：请假申请大于等于2天需要由部门总经理审批，小于2天由部门经理审批，请假申请必须经过人事经理审批。这个时候就需要包含网关

        }

        Map<String, Object> map = new HashMap<>();
        //根据上传地址后续部署流程定义，文件名称为流程定义的默认key
        map.put("processDefinitionPath", "processes/" + filename);
        map.put("processDefinitionKey", filename.substring(0, filename.lastIndexOf(".")));
        return Result.ok(map);
    }


    public static void main(String[] args) {
