activiti 7 + springboot2（六） SpringBoot2 整合 Activiti7

（一）首先 pom.xml 文件中引入相关的依赖，具体依赖如下所示： 

xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

（二）springboot 的配置文件 application.yml中添加相关的配置：

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/platform_activiti?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&useSSL=false
    username: root
    password: pass
    hikari:
      minimum-idle: 5
      maximum-pool-size: 20
      connection-test-query: SELECT 1
  activiti:
    # 开启历史库
    db-history-used: true
    history-level: audit

（三）流程资源

  资源文件放在  resources/processes 目录下，activiti程序启动会自动发布流程

  

（四）编写Applocation主程序

package com.activiti.example;

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

@SpringBootApplication
public class ActivitiApplication {

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

}

运行程序，从控制台输出中可以看到，自动创建了数据库，并且发布了"请假申请"的流程

（五）编写基于SpringBootTest的测试程序

 

package com.activiti.example;

import org.activiti.api.process.runtime.ProcessRuntime;
import org.activiti.api.task.runtime.TaskRuntime;
import org.activiti.engine.*;
import org.activiti.engine.history.HistoricTaskInstance;
import org.activiti.engine.task.Task;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;
import java.util.Map;

@RunWith(SpringRunner.class)
@SpringBootTest
public class ActivitiTest {
    @Autowired
    private RepositoryService repositoryService;
    @Autowired
    private TaskService taskService;
    @Autowired
    private RuntimeService runtimeService;
    @Autowired
    private HistoryService historyService;
/**
     * 启动一个实例
     */
    @Test
    public void startProcessInstance() {
        System.out.println("Number of process definitions : "+ repositoryService.createProcessDefinitionQuery().count());
        System.out.println("Number of tasks : " + taskService.createTaskQuery().count());
        runtimeService.startProcessInstanceByKey("myProcess_1");
    }

    /**
     * 查询用户的任务列表
     */
    @Test
    public void taskQuery() {
        //根据流程定义的key,负责人assignee来实现当前用户的任务列表查询
        List list = taskService.createTaskQuery()
                .processDefinitionKey("myProcess_1")
                .taskAssignee("john")
                .list();

        if(list!=null && list.size()>0){
            for(Task task:list){
                System.out.println("任务ID:"+task.getId());
                System.out.println("任务名称:"+task.getName());
                System.out.println("任务的创建时间:"+task.getCreateTime());
                System.out.println("任务的办理人:"+task.getAssignee());
                System.out.println("流程实例ID："+task.getProcessInstanceId());
                System.out.println("执行对象ID:"+task.getExecutionId());
                System.out.println("流程定义ID:"+task.getProcessDefinitionId());
                System.out.println("getOwner:"+task.getOwner());
                System.out.println("getCategory:"+task.getCategory());
                System.out.println("getDescription:"+task.getDescription());
                System.out.println("getFormKey:"+task.getFormKey());
                Map map = task.getProcessVariables();
                for (Map.Entry m : map.entrySet()) {
                    System.out.println("key:" + m.getKey() + " value:" + m.getValue());
                }
                for (Map.Entry m : task.getTaskLocalVariables().entrySet()) {
                    System.out.println("key:" + m.getKey() + " value:" + m.getValue());
                }

            }
        }
    }

    /**
     * 完成任务
     */
    @Test
    public void completeTask(){
        //任务ID
        String taskId = "967465fe-3367-11ea-a057-30b49ec7161f";
        taskService.complete(taskId);
        System.out.println("完成任务：任务ID："+taskId);
    }

    /**
     * 历史活动实例查询
     */
    @Test
    public void queryHistoryTask() {
        List list = historyService.createHistoricTaskInstanceQuery() // 创建历史活动实例查询
                .processInstanceId("9671cdea-3367-11ea-a057-30b49ec7161f") // 执行流程实例id
                .orderByTaskCreateTime()
                .asc()
                .list();
        for (HistoricTaskInstance hai : list) {
            System.out.println("活动ID:" + hai.getId());
            System.out.println("流程实例ID:" + hai.getProcessInstanceId());
            System.out.println("活动名称：" + hai.getName());
            System.out.println("办理人：" + hai.getAssignee());
            System.out.println("开始时间：" + hai.getStartTime());
            System.out.println("结束时间：" + hai.getEndTime());
        }
    }
}
