一：bpmn

二：java

如果没有收到信号，超过等待时间，流程进入总经理审批，如果在等待时间内收到信号，流程进入副总经理审批。

示例1：发送信号事件，流程进入副总经理审批。

repositoryService.createDeployment().name("基于事件的网关流程").addClasspathResource("bpmn/envent-base-gateway.bpmn").deploy();
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("EventBasedGatwayProcess");Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
taskService.setAssignee(task.getId(), "huihui");
taskService.complete(task.getId());Thread.sleep(1000 * 60 * 1);runtimeService.createSignalEvent("signal_vgm").send();
task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
System.out.println(task.getTaskDefinitionKey());

示例1：等待3分钟，流程进入总经理审批。

repositoryService.createDeployment().name("基于事件的网关流程").addClasspathResource("bpmn/envent-base-gateway.bpmn").deploy();
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("EventBasedGatwayProcess");Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
taskService.setAssignee(task.getId(), "huihui");
taskService.complete(task.getId());Thread.sleep(1000 * 60 * 3);task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
System.out.println(task.getTaskDefinitionKey());
