信号边界事件

一、定义

接收到信号触发事件

1. 图形标记

在这里插入图片描述

2. 设置信号选择信号

在这里插入图片描述

3. XML标记

定时边界事件的XML

   <signal id="changeContract" name="修改合同" flowable:scope="global" />
    <boundaryEvent id="Event_04efcjz" attachedToRef="Activity_1fdbk68">
      <signalEventDefinition signalRef="changeContract" />
    </boundaryEvent>

二、测试用例

2.2 信号边界事件测试用例

 ProcessDefinition processDefinition = this.deployByModelKey("SignalBoundaryInterrputingEventProcess");

        //启动两个流程实例
        ProcessInstance processInstance1 = runtimeService.startProcessInstanceById(processDefinition.getId());
        log.info("第1个流程实例的编号为：{}", processInstance1.getId());
        ProcessInstance processInstance2 = runtimeService.startProcessInstanceById(processDefinition.getId());
        log.info("第2个流程实例的编号为：{}", processInstance2.getId());

        //将实例一进行到确认合同
        Task processInstance1Task = taskService.createTaskQuery().processInstanceId(processInstance1.getId()).singleResult();
        taskService.complete(processInstance1Task.getId());
        processInstance1Task = taskService.createTaskQuery().processInstanceId(processInstance1.getId()).singleResult();
        log.info("第1个流程实例当前所在用户任务为：{}", processInstance1Task.getName());

        //将实例二进行到确认合同
        Task processInstance2Task = taskService.createTaskQuery().processInstanceId(processInstance2.getId()).singleResult();
        taskService.complete(processInstance2Task.getId());
        processInstance2Task = taskService.createTaskQuery().processInstanceId(processInstance2.getId()).singleResult();
        log.info("第2个流程实例当前所在用户任务为：{}", processInstance2Task.getName());

        //发送合同变更信号
        runtimeService.signalEventReceived("修改合同");
        log.info("发送合同变更信号完成");

        //根据流程定义查询任务
        List<Task> tasks = taskService.createTaskQuery().processDefinitionId(processDefinition.getId()).list();
        for (Task task : tasks) {
            log.info("编号为{}的流程实例当前所在用户任务为：{}", task.getProcessInstanceId(), task.getName());
        }
