1、目前我所了解到的activiti工作流想要在项目使用分为两种:

一、一种较为简单,只需要使用idea插件来画流程图。(我所使用的的插件是Activiti BPMN visualizer

二、另一种就是可以使用在线流程设计器)或者(页面设计部署自己项目中)来画流程图

本文是将流程设计页面部署到了项目

2、先来看看两种方式效果吧,是否满足您所需要结果

一、使用idea插件来画流程图

 二、流程设计页面流程图。 

3、那么现在开始实现上面两种流图以及部署启动流程

一、先来第一种方式比较简单)好入手,对于第一次接触的可以很好的去了解到这个Activiti流程引擎过程

首先你需要了解activiti的 25张表(这里就不多说了,网上很好找到

1)、先导入相关activiti依赖(一定要注意版本号

<dependencies>
        <dependency>
            &lt;groupId&gt;org.activiti</groupId&gt;
            <artifactId&gt;activiti-spring-boot-starter-basic</artifactId&gt;
            <version&gt;5.22.0</version&gt;
        </dependency&gt;
        <dependency&gt;
            <groupId>org.activiti</groupId>
            <artifactId>activiti-rest</artifactId>
            <version>5.22.0</version>
        </dependency>
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-diagram-rest</artifactId>
            <version>5.22.0</version>
        </dependency>
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-spring</artifactId>
            <version>5.22.0</version>
        </dependency>
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-json-converter</artifactId>
            <version>5.22.0</version>
        </dependency>
    </dependencies>

2)、配置相关 activiti.xml 文件连接数据库用来生成 25张表

        需要注意(xml文件名xmlid=”processEngineConfiguration”不要乱改)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/contex
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 这里可以使用 链接池 dbcp-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.cj.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/activiti?serverTimezone=Asia/Shanghai"/>
        <property name="username" value="*****" />
        <property name="password" value="*****" />
        <property name="maxActive" value="3" />
        <property name="maxIdle" value="1" />
    </bean>

    <bean id="processEngineConfiguration"
          class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
        <property name="dataSource" ref="dataSource" />
        <property name="databaseSchemaUpdate" value="true"/>
    </bean>

</beans>

3)、配置需要测试启动生成

package com.atxinxin;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.jupiter.api.Test;

/**
 * @author weixinxin 2023-06-28
 **/
public class TestCreateTable {

    @Test
    public void testCreat(){
        ProcessEngineConfiguration processEngineConfiguration =
                ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.xml","processEngineConfiguration");
        ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
        System.out.println("processEngine = " + processEngine);
    }
}

 4)、结构目录

 5)、生成的数据表

 6)、接下来需要画流程图插件开头已经提过,这里不说了,在resources包下创建一个bpmn包用来放流程图的xml文件bpmn文件右键新建一个文件例如(activiti.bpmn20.xml)

 7)、右键最下面打开Diagram界面

8)、再空白页面右键各个事件介绍三个必不可少的)启动节点结束

 

 

 

 10)、到这里会玩的大概也差不多了,怎么画就不详细说了,我这里把我的 evection.bpmn20.xml 放出来。对于png文件把后缀名改成png就可以

<?xml version="1.0" encoding="UTF-8"?>

 这里 创建申请-zhansa经理lisi  总经理wangwu  财务-zhaoliu

11)、部署流程图 部署完成查看act_re_deployment

@Test
    public void testDeployment(){
        // 1.创建processEngine
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        // 2.获取RepositoryService
        RepositoryService repositoryService = processEngine.getRepositoryService();
        // 3.使用service进行流程部署 ,定义流程名,把 bpmn 和 png 部署到数据库
        Deployment deployment = repositoryService.createDeployment()
                .name("出差申请流程")
                .addClasspathResource("bpmn/evection.bpmn20.xml")
                .addClasspathResource("bpmn/evection.png")
                .deploy();
        System.out.println("流程部署id = " + deployment.getId());
        System.out.println("流程部署name = " + deployment.getName());
    }

 12)、启动流程实例

/**
    *@Description 启动流程实例
    *@author weixinxin
    *@Date   17:17 2023/6/28
    **/
    @Test
    public void testStartProcess(){
        // 1. 创建ProcessEngine
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        // 2. 获取RuntimeService
        RuntimeService runtimeService = processEngine.getRuntimeService();
        // 3. 根据流程定义的id启动流程
        ProcessInstance myEvection = runtimeService.startProcessInstanceByKey("evection");
        System.out.println("流程定义id = " + myEvection.getProcessDefinitionId());
        System.out.println("流程实例id = " + myEvection.getId());
        System.out.println("当前活动id = " + myEvection.getActivityId());
    }

 13)、查询个人待办任务

/**
    *@Description 查询个人执行任务
    *@author weixinxin
    *@Date   17:33 2023/6/28
    **/
    @Test
    public void testFindPersonalTaskList(){
        // 1.获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        // 2.获取taskService
        TaskService taskService = processEngine.getTaskService();
        // 3.根据流程key任务负责查询任务
        List<Task> list = taskService.createTaskQuery()
                .processDefinitionKey("evection")
                .taskAssignee("zhangsan")
                .list();
        for (Task task : list) {
            System.out.println("流程实例id = " + task.getProcessInstanceId());
            System.out.println("任务id = " + task.getId());
            System.out.println("任务负责人id = " + task.getAssignee());
            System.out.println("任务名称 = " + task.getName());
        }
    }

 14)、完成个人任务,依次完成zhangsan、lisi、wangwu、zhaoliu的任务

/**
    *@Description 完成个人任务
    *@author weixinxin
    *@Date   17:45 2023/6/28
    **/
    @Test
    public void completTesk(){
        // 1.获取流程引擎
        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
        // 2.获取taskService
        TaskService taskService = processEngine.getTaskService();
        
      /*Task task = taskService.createTaskQuery() //完成zhangsan任务
                .processDefinitionKey("evection")
                .taskAssignee("zhangsan")
                .singleResult();*/

        /*Task task = taskService.createTaskQuery() //完成lisi任务
                .processDefinitionKey("evection")
                .taskAssignee("lisi")
                .singleResult();*/

        /*Task task = taskService.createTaskQuery() //完成wangwu任务
                .processDefinitionKey("evection")
                .taskAssignee("wangwu")
                .singleResult();*/

        Task task = taskService.createTaskQuery() //完成zhaoliu任务
                .processDefinitionKey("evection")
                .taskAssignee("zhaoliu")
                .singleResult();

        System.out.println("流程实例id = " + task.getProcessInstanceId());
        System.out.println("任务id = " + task.getId());
        System.out.println("任务负责人id = " + task.getAssignee());
        System.out.println("任务名称 = " + task.getName());

        taskService.complete(task.getId());
    }

 以上是idea插件简单的activiti工作引擎的使用过程
