定时器事件

可以用在开始事件、中间事件、边界事件上边界事件可以是中断和非中断边界事件

需要开启异步任务配置全局配置类中

config.setAsyncExecutorActivate(true);

触发时间后会在

P10DT5M表示每10天5分钟为一个周期PM10M每10分钟为一个周期PT1M一分钟后执行一次PT20S20秒后执行一次

timerEventDefinitiontimeDurationP10DT5M/timeDuration

R3/PT10H表示重复3次每次间隔10小时R3/PT3S循环3次间隔3秒R/PT1H每隔1小时执行一次

timerEventDefinitiontimeCycleR3/PT10H/timeCycle

使用场景流程只需要启动一次、流程需要在特定的时间间隔重复启动。

子流程不能有定时开始事件流程部署后马上开始定时事件不需要手动启动流程如果手动启动后会额外启动一个流程当部署带有定时器启动事件的流程的更新版本时上一版本的定时器作业会被移除

/startEvent2.中间事件

使用场景定时器中间事件是一个Catching事件当执行到达捕获事件节点

就会启动一个定时器并一直等待触发只有到达指定时间定时器才被触发。

定时20秒后执行

--timeDurationPT20S/timeDuration/timerEventDefinition

使用场景当某个用户任务或者子流程在规定的时间后还没有执行。

那么我们就可以通过定时器边界事件来触发执行特定的处理流程。

其中cancelActivity属性用于说明该事件是否为中断事件。

cancelActivity属性值默认为true表示它是边界中断事件当该边界事件触发时它所依附的活动实例被终止原有的执行流会被中断流程将沿边界事件的外出顺序流继续流转。

如果将其设置为false表示它是边界非中断事件当边界事件触发时则原来的执行流仍然存在所依附的活动实例继续执行同时也执行边界事件的外出顺序流。
