二、application配置

1、application.yml

spring:
  profiles:
    active: @profiles.active@
  main:
    allow-circular-references: true
  web:
    resources:
      static-locations: classpath:/static/
  thymeleaf:
    cache: false
    prefix: classpath:/templates/
  security:
    user:
      name: jing
      password: 1234

2、application-dev.yml

server:
  port: 3001

spring:
  #数据源
  datasource:
    mysql:
      driverClassName: com.mysql.cj.jdbc.Driver
      jdbcUrl: jdbc:mysql://127.0.0.1:3306/wgz-security-auth?characterEncoding=utf8&amp;useSSL=false&amp;serverTimezone=UTC&amp;rewriteBatchedStatements=true&amp;allowPublicKeyRetrieval=true&amp;autoReconnect=true&amp;allowMultiQueries=true
      type: com.zaxxer.hikari.HikariDataSource

      maximumPoolSize: 20
      autoCommit: true
      poolName: HikariPool_mysql
      maxLifetime: 600000
      connectionTestQuery: SELECT 1

  # redis
  redis:
    database: 2
    host: 127.0.0.1
    port: 6379
    username:
    password: 123456
    timeout: -1
    lettuce:
      pool:
        max-active: 8  # 连接池最大连接数（使用负值表示没有限制） 默认 8
        max-wait: -1   # 连接池最大阻塞等待时间（使用负值表示没有限制） 默认 -1
        max-idle: 8    # 连接池中的最大空闲连接 默认 8
        min-idle: 0    # 连接池中的最小空闲连接 默认 0


#knife4j文档配置
knife4j:
  enable: true  #是否开启Swagger
  production: false #当前环境是否为生产环境
  basic:
    enable: true  #进入界面是否需要账号密码
    username: admin
    password: admin123131

        //私钥解密
        System.out.println("解密后字符串：" + decryptAes(encrypt, AES_SECRET_KEY));
    }
}

八、自定义密码处理组件

import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Component;

import static com.wgz.auth.constant.Common.AES_SECRET_KEY;

//一、自定义密码处理组件
@Component
public class CustomPwdEncoderUtil implements PasswordEncoder {

    @Override
    public String encode(CharSequence rawPassword) {
        //进行MD5加密
        //MD5.encrypt(rawPassword.toString());
        return AesUtil.encryptAes(String.valueOf(rawPassword), AES_SECRET_KEY);
    }

    @Override
    public boolean matches(CharSequence rawPassword, String encodePassword) {
        //判断是否相等
        //return encodePassword.equals(MD5.encrypt(rawPassword.toString()));
        return AesUtil.encryptAes(String.valueOf(rawPassword), AES_SECRET_KEY).equals(encodePassword);
    }
}

九、Response工具

import com.fasterxml.jackson.databind.ObjectMapper;
import com.wgz.auth.constant.Result;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class ResponseUtil {

    public static void out(HttpServletResponse response, Result r) {
        ObjectMapper mapper = new ObjectMapper();
        response.setStatus(HttpStatus.OK.value());
        response.setContentType(MediaType.APPLICATION_JSON_UTF8_VALUE);
        try {
            mapper.writeValue(response.getWriter(), r);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

十、common constant 常量

import java.time.Duration;

public interface Common {
    /**
     * spring security 继承过滤器(UsernamePasswordAuthenticationFilter)验证方式：TokenLoginFilter
     */
    String TOKEN_PREF_DEFAULT = "AUTH:TOKEN:DEFAULT:";
    /**
     * spring security 自定义接口验证方式：
     * com.wgz.auth.controller.LoginController#doLogin(com.wgz.auth.entity.UserLoginDto)
     */
    String TOKEN_PREF_INTERFACE = "AUTH:TOKEN:INTERFACE:";
    /**
     * 登录过期时间
     */
    Duration REDIS_TIME_OUT = Duration.ofHours(3);

    /**
     * AES密钥
     */
    String AES_SECRET_KEY = "a57e3db23f9c89e606abe9b9b5fc7f30";
}

十一、自定义UserDetail类

import com.wgz.auth.entity.user.UserVo;
import io.swagger.v3.oas.annotations.media.Schema;
import lombok.*;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.User;

import java.util.Collection;

/**
 * 自定义用户类（继承Security里的User类）
 */
@Getter
@Setter
@ToString
@Schema(description = "自定义用户类: 继承Security里的User类")
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
     */
    private UserVo userVo;

    public CustomUser(UserVo userVo, Collection<? extends GrantedAuthority> authorities) {
        //调用父类构造器初始化信息
        super(userVo.getUserName(), userVo.getPassword(), authorities);
        this.userVo = userVo;
    }
}

十二、登录过滤器配置

import com.alibaba.fastjson.JSONObject;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.wgz.auth.entity.user.UserLoginDto;
import com.wgz.auth.constant.ResponseEnum;
import com.wgz.auth.constant.Result;

        //返回目标认证对象

    }
    /**

     */
    @Override

                                            FilterChain chain,
                                            Authentication auth) {
        if (auth.getPrincipal() == null) {
            throw new CustomException(ResponseEnum.PARAM_ERROR.getCode(),

        ResponseUtil.out(response, new Result(ResponseEnum.PARAM_ERROR.getCode(),
        "用户名或密码错误！", null));
    }
}

十三、认证过滤器配置

import com.alibaba.fastjson.JSONObject;
import com.wgz.auth.constant.ResponseEnum;
import com.wgz.auth.constant.Result;
import com.wgz.auth.entity.user.UserVo;
import com.wgz.auth.util.ResponseUtil;

import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
@RequiredArgsConstructor
public class UserDetailServiceImpl implements UserDetailsService {

    private final UserMapper userMapper;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        LambdaQueryWrapper<UserVo> lambdaQueryUser = new LambdaQueryWrapper<>();
        lambdaQueryUser.eq(UserVo: :getUserName, username);
        lambdaQueryUser.eq(UserVo: :getIsDelete,
        0);
        lambdaQueryUser.last("limit 1");
        UserVo userVo = userMapper.selectOne(lambdaQueryUser);
        //判断用户是否为空
        if (null == userVo) {
            throw new UsernameNotFoundException("用户不存在");
        }
        //判断用户状态是否可用
        if (userVo.getStatus() == 0) {
            throw new RuntimeException("用户已禁用...");
        }
        //手动设置权限，也可以通过数据库查询获取
        List<GrantedAuthority> auths = AuthorityUtils.commaSeparatedStringToAuthorityList("addUser,findAll,ROLE_admin,ROLE_user");
        return new CustomUser(userVo, auths);
    }
}
