1. Flow chart

2. Distribution of Personal Tasks 1 (Direct Assignment of Translators)

1. Configuration of Task Node in Flow Chart

2. Code

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
//Deploy process definitions and start process instances
	@Test
	public void testTask() throws Exception {
		
		// 1 Release process
		InputStream inputStreamBpmn = this.getClass().getResourceAsStream("taskProcess.bpmn");
		InputStream inputStreamPng = this.getClass().getResourceAsStream("taskProcess.png");
		processEngine.getRepositoryService()//
						.createDeployment()//
						.addInputStream("userTask.bpmn", inputStreamBpmn)//
						.addInputStream("userTask.png", inputStreamPng)//
						.deploy();
		
		// 2 Start-up process
		//Setting process variables while starting process instances
		ProcessInstance pi = processEngine.getRuntimeService()//
							.startProcessInstanceByKey("taskProcess");
		System.out.println("pid:" + pi.getId());
	}
	
//Query my personal task list
	@Test
	public void findMyTaskList(){
		String userId = "Zhang Sanfeng";
		List<Task> list = processEngine.getTaskService()//
		                .createTaskQuery()//
		                .taskAssignee(userId)//Designated Personal Task Query
		                .list();
		for(Task task:list ){
			System.out.println("id="+task.getId());
			System.out.println("name="+task.getName());
			System.out.println("assinee="+task.getAssignee());
			System.out.println("createTime="+task.getCreateTime());
			System.out.println("executionId="+task.getExecutionId());
			
		}
	}
	
//Complete tasks
	@Test
	public void completeTask(){
		String taskId = "3209";
		processEngine.getTaskService()//
					.complete(taskId);//
		System.out.println("Complete tasks");
	}

Analysis:

1. Zhang Sanfeng is a personal task manager
2. However, the managers who assign tasks in this way are not flexible enough, because the managers of tasks in project development should not place XML files.

3. Personal Task Assignment Mode 2 (Using Process Variables)

1. Configuration of Task Node in Flow Chart
2. Code

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
//Deploy process definitions and start process instances
	@Test
	public void testTask() throws Exception {
		
		// 1 Release process
		InputStream inputStreamBpmn = this.getClass().getResourceAsStream("taskProcess.bpmn");
		InputStream inputStreamPng = this.getClass().getResourceAsStream("taskProcess.png");
		processEngine.getRepositoryService()//
						.createDeployment()//
						.addInputStream("userTask.bpmn", inputStreamBpmn)//
						.addInputStream("userTask.png", inputStreamPng)//
						.deploy();
		
	// 2 Start-up process
	//Setting process variables while starting process instances
		Map<String, Object> variables = new HashMap<String, Object>();
		variables.put("userID", "Zhang Cuisan");
		ProcessInstance pi = processEngine.getRuntimeService()//
							.startProcessInstanceByKey("taskProcess",variables);
		System.out.println("pid:" + pi.getId());
	}
	
	//Query my personal task list
	@Test
	public void findMyTaskList(){
		String userId = "Zhang Cuisan";
		List<Task> list = processEngine.getTaskService()//
		                .createTaskQuery()//
		                .taskAssignee(userId)//Designated Personal Task Query
		                .list();
		for(Task task:list ){
			System.out.println("id="+task.getId());
			System.out.println("name="+task.getName());
			System.out.println("assinee="+task.getAssignee());
			System.out.println("createTime="+task.getCreateTime());
			System.out.println("executionId="+task.getExecutionId());
			
		}
	}
	
	//Complete tasks
	@Test
	public void completeTask(){
		String taskId = "3209";
		processEngine.getTaskService()//
					.complete(taskId);//
		System.out.println("Complete tasks");
	}

Analysis:

1. Zhang Cuishan is a personal task manager
2. In development, you can specify the next task handler in the page, and set the next task handler through process variables.

4. Personal Task Assignment Mode 3 (Use Class)

1. Configuration of Task Node in Flow Chart


At this point, the flow chart's XML file is shown as follows:

2.TaskListenerImpl class, used to set up task handlers

public class TaskListenerImpl implements TaskListener {

	/**Assignment of Personal Tasks and Group Tasks*/
	@Override
	public void notify(DelegateTask delegateTask) {
		String assignee = "Zhang Wuji";
		//Assignment of Personal Tasks
		delegateTask.setAssignee(assignee);
	}

}

3. Code

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
//Deploy process definitions and start process instances
	@Test
	public void testTask() throws Exception {
		
		// 1 Release process
		InputStream inputStreamBpmn = this.getClass().getResourceAsStream("taskProcess.bpmn");
		InputStream inputStreamPng = this.getClass().getResourceAsStream("taskProcess.png");
		processEngine.getRepositoryService()//
						.createDeployment()//
						.addInputStream("userTask.bpmn", inputStreamBpmn)//
						.addInputStream("userTask.png", inputStreamPng)//
						.deploy();
		
		// 2 Start-up process
		ProcessInstance pi = processEngine.getRuntimeService()//
							.startProcessInstanceByKey("taskProcess");
		System.out.println("pid:" + pi.getId());
	}
	
	//Query my personal task list
	@Test
	public void findMyTaskList(){
		String userId = "Zhang Wuji";
		List<Task> list = processEngine.getTaskService()//
		                .createTaskQuery()//
		                .taskAssignee(userId)//Designated Personal Task Query
		                .list();
		for(Task task:list ){
			System.out.println("id="+task.getId());
			System.out.println("name="+task.getName());
			System.out.println("assinee="+task.getAssignee());
			System.out.println("createTime="+task.getCreateTime());
			System.out.println("executionId="+task.getExecutionId());
			
		}
	}
	
	//Complete tasks
	@Test
	public void completeTask(){
		String taskId = "3408";
		processEngine.getTaskService()//
					.complete(taskId);//
		System.out.println("Complete tasks");
	}

	//Personal tasks can be assigned from one person to another (claim tasks)
	@Test
	public void setAssigneeTask(){
		//Task ID
		String taskId = "3408";
		//Designated Claim Agent
		String userId = "Zhou Zhiruo";
		processEngine.getTaskService()//
					.setAssignee(taskId, userId);
	}

Analysis:

1. delegateTask.setAssignee(assignee) is used in the class to assign a personal task to the administrator. At this time, Zhang Wuji is the administrator of the next task.

2. By processing Engine. getTaskService (). setAssignee (taskId, userId); assign personal tasks from one person to another, at this time Zhang Wuji is no longer the next task manager, but changed to Zhou Zhiruo.

3. In the process of development, the managers of each task can be stipulated. For example, the leader of Zhang San is Li Si, and the leader of Li Si is Wang Wu. If Zhang San submits a task, he can query that the leader of Zhang San is Li Si, and set up the manager of the next task by means of classes.

5. Summary

Personal tasks and three ways of assignment:

1. Write assignee = "Zhang Sanfeng" directly in taskProcess.bpmn“
2. Write assignee = "#{userID}" in taskProcess.bpmn, and the value of the variable is String. Use process variables to specify the dealer
3. Using the TaskListener interface, to implement the interface in the class, define in the class:

delegateTask.setAssignee(assignee);// Designated Personal Task Manager

Use task ID and reassignment of transactors by transactors:

     processEngine.getTaskService()//.setAssignee(taskId, userId);
