BoundaryEvent组件

BoundaryEvent组件
- BoundaryEvent总述
  - MessageBoundaryEvent
  - SignalBoundaryEvent
- 关于补偿与取消边界事件在我的这篇帖子里面有相关demo讲解【https://blog.csdn.net/Pan1458689676/article/details/82711607#cancelendevent】
  - CancelBoundaryEvent
  - CompensationBoundaryEvent

BoundaryEvent总述

这里写图片描述

BoundaryEvent分为六种，第一种为时间Boundary事件，第二种为错误Boundary事件，第三种消息Boundary事件，第四种为取消Boundary事件，第五种为补偿Boundary事件，第六种为信号Boundary事件。边界事件依附于事件存在。

MessageBoundaryEvent

这里写图片描述

注意部分

这里写图片描述

ServiceTask

这里写图片描述

ServiceTask

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

@Test
public void MessageBoundary() throws InterruptedException{
    Deployment deployment = repositoryService.createDeployment()
                    .name("MessageBoundary")
                    .addClasspathResource("bpmn/MessageBoundary.bpmn")
                    .addClasspathResource("bpmn/MessageBoundary.png")
                    .deploy();
    System.out.println("部署ID："+deployment.getId());
    System.out.println("部署名称："+deployment.getName());

    ProcessInstance pi = runtimeService.startProcessInstanceByKey("MessageBoundary");
    Execution ex = runtimeService.createExecutionQuery().processDefinitionId(pi.getProcessDefinitionId()).activityId("boundarymessage1").singleResult();
    runtimeService.messageEventReceived("msgName", ex.getId());
    Thread.sleep(1000 *10);
}

这里写图片描述

SignalBoundaryEvent

如果有两个活动信号边界事件捕获相同的信号事件，则两个边界事件都会被触发，即使它们是不同流程实例的一部分。
