Activiti6 示例1--部署流程、启动流程、查询第一个流程节点、查询第二个流程节点等信息

一、项目代码框架

该eclipse 版本为2017年版本的，配置工作流插件请参考《Eclipse 下 Activiti Designer 插件安装教程》

二：项目代码：

package com.alan.activiti6Demo.fristAct;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;

public class FirstAct {


	public static void main(String[] args) throws Exception {
		//创建引擎,这步骤会进行数据库表的创建或者更新操作
		ProcessEngine engine=ProcessEngines.getDefaultProcessEngine();
		//部署流程文件至 数据库表中。
		RepositoryService rs=engine.getRepositoryService();//资源服务
		RuntimeService  rts = engine.getRuntimeService();//运行时服务
		TaskService ts=engine.getTaskService();//流程任务处理服务
		/*
		 * 一次部署，可以包含多个文件：流程图、流程定义文件
		 * 部署的文件信息放入在act_ge_bytearray 中
		 * 部署记录信息 放入在act_re_deployment 中
		 */
		rs.createDeployment().addClasspathResource("first.bpmn").deploy();
		ProcessInstance pi=rts.startProcessInstanceByKey("myProcess");//每启动流程一次,则可以获取一个流程实例对象。流程定义文件可以启动多次

		// 查询第一个任务
		Task task = ts.createTaskQuery().singleResult();
		System.out.println("第一个任务完成前，当前任务名称：" + task.getName());
		// 完成第一个任务
		ts.complete(task.getId());
		// 查询第二个任务
		task = ts.createTaskQuery().singleResult();
		System.out.println("第二个任务完成前，当前任务名称：" + task.getName());
		// 完成第二个任务（流程结束）
		ts.complete(task.getId());
		task = ts.createTaskQuery().singleResult();
		engine.close();//关闭引擎
		System.exit(0);//退出
	}



}
