IntermediateEvent组件

IntermediateEvent分为抛出事件与捕获事件。基本与边界事件用法类似。依然以信号，消息，错误，时间为载体。具体分为六种。功能的话基本上直接翻译就大致明白。

这里写图片描述

官网上也没有详细的描述，这里主要以两个demo做讲解。
这里写图片描述

Demo1【Timer+Signal+Message】

  • 并行网关前三行为测试信号抛出中间事件与信号捕获中间事件。

ServiceTask绑定如下【两个都绑定了如下委托执行类】
这里写图片描述

ServiceTask

public class ServiceTask implements JavaDelegate {
    @Override
    public void execute(DelegateExecution execution) {
        System.out.println("ServiceTask");
    }
}
  • 并行网关第四行为测试消息捕获中间事件。

ServiceTask绑定如下

这里写图片描述

ServiceTask

public class Message implements JavaDelegate {
    @Override
    public void execute(DelegateExecution execution) {
        System.out.println("Message");
    }
}
  • 并行网关之后为测试事件捕获中间事件。

ServiceTask绑定如下

这里写图片描述

ServiceTask

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

测试代码

@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("部署名称："+deployment.getName());
    ProcessInstance pi = runtimeService.startProcessInstanceByKey("intermediate");

    Task task = taskService.createTaskQuery().processInstanceId(pi.getId()).singleResult();
    System.out.println("当前流程任务：" + task.getName());
    taskService.complete(task.getId());

    //发送message事件
    Execution ex = runtimeService.createExecutionQuery()
            .processDefinitionId(pi.getProcessDefinitionId())
            .activityId("messageintermediatecatchevent1")
            .singleResult();
    runtimeService.messageEventReceived("msgName", ex.getId());
    Thread.sleep(1000 *15);
}

这里写图片描述

Demo2【Compensation+None】

流程图总览

这里写图片描述

NoneThrowingEvent绑定

该事件通常用于指示流程中实现的某些状态。一般用于做监听。
这里写图片描述

ListenTest 

public class ListenTest implements ExecutionListener {
    @Override
    public void notify(DelegateExecution execution) {
        System.out.println("执行监听");
    }
}

ServiceTask绑定
这里写图片描述

ServiceTask

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

ServiceTask2

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

测试代码

@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("部署名称："+deployment.getName());
    ProcessInstance pi = runtimeService.startProcessInstanceByKey("Middle");
}

这里写图片描述

CompensationThrowingEvent注意事项【详细可以参考官网】

CompensationThrowingEvent可用于触发补偿。

如果在包含子流程的范围内抛出补偿且子流程包含具有补偿处理程序的活动，则补偿仅在抛出补偿时成功完成后才传播到子流程。如果嵌套在子流程中的某些活动已完成并附加了补偿处理程序，则如果尚未完成包含这些活动的子流程，则不会执行补偿处理程序。

数据可视化 Java 关系型数据库
01-认识Activiti
类似如请假、离职、出差、报销这种有审批流程的业务，我们都可以称之为工作流（也叫流程引擎），它可以帮助用户实现一个审批流程的可视化，借助于工作流引擎可以搭建客户关系管理系统（CRM）、运输管理系统（TMS）、仓储管理系统（WMS）、财务费用系统等多种复杂业务系统。
