目录

一、Activiti环境

1、idea安装插件
* Bpmn图形其实是通过xml表示业务流程（.bpmn文件使用文本编辑器打开）
* File | Settings | Plugins
    - 搜索actiBPM（Activiti BPMN visualizer）
2、数据库支持
* 阿里云PolarDB
    - 集群白名单
        ~ 新增ip白名单分组（www.ip138.com）
        ~ 选择安全组
    - 账号管理
        ~ 创建账号
    - 基本信息
        ~ 链接地址（主地址申请公网）
        ~ 登录数据库
* 创建数据库（名字任意）
    - CREATE DATABASE activiti DEFAULT CHARACTER SET utf8;
3、创建maven工程

4、activiti入门
  • 流程符号
* 事件Event
    - 开始事件
    - 中间事件
    - 结束事件
* 活动Activity
    - 用户任务
    - 服务任务
    - 子流程
* 网关GateWay
    - 排他网关（x）
    - 并行网关（+）
    - 包容网关（+）
    - 综合网关
    - 事件网关（+）
* 流向Flow
    - 顺序流
    - 消息流
    - 关联
    - 数据关联
  • 流程设计器使用
* 右击目录 -> new -> New Activiti 6.x BPMN 2.0 file
* 右击xml编辑面板 -> View BPMN (Activiti) Diagram
* 右击画板
    - Connection：连接
    - Event：事件
    - Task：任务
    - Gateway：网关
    - Container：容器
    - Boundary event：边界事件
    - Intermediate event：中间事件
5、流程定义部署
  • src/test/java/com/linjincheng/test/ActivitiDemo.java
package com.linjincheng.test;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Deployment;
import org.junit.Test;

public class ActivitiDemo {
  @Test
  public void testDeployment() {
    // 改动四张表：act_re_deployment、act_re_procdef、act_ge_bytearray、act_ge_property
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RepositoryService repositoryService = processEngine.getRepositoryService();
    Deployment deploy = 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=" + deploy.getId());
    System.out.println("流程部署名字=" + deploy.getName());
  }
}
6、启动流程-任务查询-完成任务
  • src/test/java/com/linjincheng/test/ActivitiDemo.java
package com.linjincheng.test;

import org.activiti.engine.*;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.junit.Test;

import java.util.List;

public class ActivitiDemo {
  @Test
  public void testStartProcess() {
    // 启动流程
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    RuntimeService runtimeService = processEngine.getRuntimeService();
    ProcessInstance instance = runtimeService.startProcessInstanceByKey("evection");
    System.out.println("流程定义ID：" + instance.getProcessDefinitionId());
    System.out.println("流程实例ID：" + instance.getId());
    System.out.println("当前活动的ID：" + instance.getActivityId());
  }

  @Test
  public void testFindPersonalTaskList() {
    // 任务查询
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    List<Task> taskList = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("zhangsan").list();
    for (Task task : taskList) {
      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=" + task.getAssignee());
      System.out.println("任务名称=" + task.getName());
    }
  }

  @Test
  public void completTask() {
    // 完成任务
    ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
    TaskService taskService = processEngine.getTaskService();
    // taskService.complete("7505");
    // Task task = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("jerry").singleResult();
    // Task task = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("jack").singleResult();
    Task task = taskService.createTaskQuery().processDefinitionKey("evection").taskAssignee("rose").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=" + task.getAssignee());
    System.out.println("任务名称=" + task.getName());
    taskService.complete(task.getId());
  }
}
