篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了第十五篇Flowable事件-信号事件相关的知识，希望对你有一定的参考价值。
Flowable中的信号事件
1.开始事件
然后设置相关的属性，并定义一个信号
然后在我们声明的信号开始引用我们上面创建的信号

部署流程：
/**
* Deploy
*/
@Test
void testDeploy() throws Exception
//RepositoryService repositoryService = processEngine.getRepositoryService();
Deployment deploy = repositoryService.createDeployment()
.addClasspathResource("信号启动事件.bpmn20.xml")
.name("信号启动事件")
.deploy();
System.out.println("deploy.getId() = " + deploy.getId());
System.out.println("deploy.getName() = " + deploy.getName());
System.out.println("部署开始的时间：" + new Date());
//TimeUnit.MINUTES.sleep(3);
流程是一个信息启动事件，所以我们需要释放对应的信号来触发流程的启动
/**
* 通过信号发送来触发信号启动事件的执行
* 全局的信息
*/
@Test
void signalReceived() throws Exception
runtimeService.signalEventReceived("firstSignal");
// 我们得保证容器的运行，所以需要阻塞
TimeUnit.MINUTES.sleep(1);
通过输出语句可以看到自定义任务触发了
我们可以把信息的作用域由原来的golbal全局的调整为processInstance，测试后发现还是执行了，说明在启动事件信息的作用域其实是不起作用的。
<signal id="signal01" name="firstSignal" flowable:scope="processInstance"></signal>
2.中间捕获事件
案例如下：当我们启动事件后，会阻塞在这个消息获取中间事件处，等待相关信号后才会继续流转。
