Activiti 6.x【11】IntermediateEvent

發布時間：2025/7/25 编程问答 9 豆豆

生活随笔收集整理的這篇文章主要介紹了 Activiti 6.x【11】IntermediateEvent 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

IntermediateEvent組件

IntermediateEvent組件
- - Demo1【Timer+Signal+Message】
  - Demo2【Compensation+None】
  - CompensationThrowingEvent注意事項【詳細可以參考官網】

IntermediateEvent分為拋出事件與捕獲事件。基本與邊界事件用法類似。依然以信號，消息，錯誤，時間為載體。具體分為六種。功能的話基本上直接翻譯就大致明白。

官網上也沒有詳細的描述，這里主要以兩個demo做講解。

Demo1【Timer+Signal+Message】

并行網關前三行為測試信號拋出中間事件與信號捕獲中間事件。

ServiceTask綁定如下【兩個都綁定了如下委托執行類】

ServiceTask

public class ServiceTask implements JavaDelegate {@Overridepublic void execute(DelegateExecution execution) {System.out.println("ServiceTask");} }

并行網關第四行為測試消息捕獲中間事件。

ServiceTask綁定如下

ServiceTask

public class Message implements JavaDelegate {@Overridepublic void execute(DelegateExecution execution) {System.out.println("Message");} }

并行網關之后為測試事件捕獲中間事件。

ServiceTask綁定如下

ServiceTask

public class Over implements JavaDelegate {@Overridepublic void execute(DelegateExecution execution) {System.out.println("Over");} }

測試代碼

@Test public void Intermediate() throws InterruptedException{Deployment deployment = repositoryService.createDeployment().name("intermediate").addClasspathResource("bpmn/intermediate.bpmn").addClasspathResource("bpmn/intermediate.png").deploy();System.out.println("部署ID："+deployment.getId());System.out.println("部署名稱："+deployment.getName());ProcessInstance pi = runtimeService.startProcessInstanceByKey("intermediate");Task task = taskService.createTaskQuery().processInstanceId(pi.getId()).singleResult();System.out.println("當前流程任務：" + task.getName());taskService.complete(task.getId());//發送message事件Execution ex = runtimeService.createExecutionQuery().processDefinitionId(pi.getProcessDefinitionId()).activityId("messageintermediatecatchevent1").singleResult();runtimeService.messageEventReceived("msgName", ex.getId());Thread.sleep(1000 *15); }

Demo2【Compensation+None】

流程圖總覽

NoneThrowingEvent綁定

該事件通常用于指示流程中實現的某些狀態。一般用于做監聽。

ListenTest

public class ListenTest implements ExecutionListener {@Overridepublic void notify(DelegateExecution execution) {System.out.println("執行監聽");} }

ServiceTask綁定

ServiceTask

public class ServiceTask implements JavaDelegate {@Overridepublic void execute(DelegateExecution execution) {System.out.println("ServiceTask");} }

ServiceTask2

public class ServiceTask2 implements JavaDelegate {@Overridepublic void execute(DelegateExecution execution) {System.out.println("ServiceTask2");} }

XML代碼

測試代碼

@Test public void Middle() throws InterruptedException{Deployment deployment = repositoryService.createDeployment().name("Middle").addClasspathResource("bpmn/Middle.bpmn").addClasspathResource("bpmn/Middle.png").deploy();System.out.println("部署ID："+deployment.getId());System.out.println("部署名稱："+deployment.getName());ProcessInstance pi = runtimeService.startProcessInstanceByKey("Middle"); }

CompensationThrowingEvent注意事項【詳細可以參考官網】

CompensationThrowingEvent可用于觸發補償。

如果在包含子流程的范圍內拋出補償且子流程包含具有補償處理程序的活動，則補償僅在拋出補償時成功完成后才傳播到子流程。如果嵌套在子流程中的某些活動已完成并附加了補償處理程序，則如果尚未完成包含這些活動的子流程，則不會執行補償處理程序。
