**\#1.部署流程定义涉及到的表**

/**
    	 * 部署流程定义
    	 */
    	@Test
    	public void deploy() {
    		Deployment deployment = processEngine.getRepositoryService()//获取部署相关Service
    				.createDeployment()//创建部署
    				.addClasspathResource("diagrams/HelloWorld.bpmn")//加载资源文件
    				.addClasspathResource("diagrams/HelloWorld.png")//加载资源文件
    				.name("HelloWorld")
    				.deploy();//部署
    		System.out.println("部署ID："+deployment.getId());
    		System.out.println("部署Name："+deployment.getName());
    	}

\#流程部署表

select \* from act\_re\_deployment

\#流程定义表

select \* from act\_re\_procdef

\#资源文件表

select \* from act\_ge\_bytearray

\#系统配置表

select \* from act\_ge\_property

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

/**
    	 * 启动流程实例
    	 */
    	@Test
    	public void start() {
    		ProcessInstance pi = processEngine.getRuntimeService()//运行时Service
    			.startProcessInstanceByKey("myProcess");//流程定义表的Key字段
    		System.out.println("流程实例ID："+pi.getId());
    		System.out.println("流程实例ID："+pi.getProcessDefinitionId());
    	}

**\#2.启动流程实例涉及到的表**

\# 流程实例运行时   执行对象表

select \* from act\_ru\_execution

\# 流程实例运行时  身份联系表

select \* from act\_ru\_identitylink

\# 流程实例运行时  用户任务表

select \* from act\_ru\_task

\# 活动节点历史表

select \* from act\_hi\_actinst

\# 身份联系表  历史

select \* from act\_hi\_identitylink

\# 流程实例表  历史

select \* from act\_hi\_procinst

\# 历史任务表

select \* from act\_hi\_taskinst

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#

/**
    	 * 完成任务
    	 */
    	@Test
    	public void completeTask() {
    		processEngine.getTaskService()//任务相关Service
    			.complete("2504");
    	}

**\#3.结束流程实例涉及到的表**

\#运行时  表数据全部清空

\#历史表  表数据修改  或者增加了数据表

**\#4.设置流程变量涉及到的表**

\#运行时流程变量表

select \* from act\_ru\_variable

\#历史流程变量表

select \* from act\_hi\_varinst
