JBPM (四) 服务和实例介绍

• 服务的使用--流程例子

	public void testDeploy()
	{
		//得到服务引擎，管理服务的创建
		ProcessEngine processEngine=Configuration.getProcessEngine();
		//创建repositoryService服务，可以实现部署、删除流程等
		RepositoryService repositoryService=processEngine.getRepositoryService();
		//部署流程
		repositoryService.createDeployment().addResourceFromClasspath("test.jpdl.xml").deploy();
	}

	//创建流程实例
	public void testCreateInstance()
	{
		ProcessEngine processEngine=Configuration.getProcessEngine();
		ExecutionService executionService=processEngine.getExecutionService();
		//通过已经存在的实例的key值，获得实例
		ProcessInstance processInstance=executionService.startProcessInstanceByKey("test");
		System.out.println("流程实例ID===="+processInstance.getId());
	}

	public void testGetTask()
	{
		ProcessEngine processEngine=Configuration.getProcessEngine();
		TaskService taskService=processEngine.getTaskService();
		List<Task> tasks=taskService.findPersonalTasks("李四");
		
		Task task=tasks.get(0);
		
		System.out.println("任务数量："+tasks.size());
		System.out.println("任务名称："+task.getActivityName());
		System.out.println("任务人员："+task.getAssignee()+"任务ID"+task.getId());
		
	}

	public void testCompeleteTask()
	{
		ProcessEngine processEngine=Configuration.getProcessEngine();
		TaskService taskService=processEngine.getTaskService();
		
		taskService.completeTask("8");
		
	}
