flowable-流程中心设计之中间事件(六)

作者：互联网

简介 

中间捕获事件，是可以作为一个流程节点存在，可以是抛出型,也可以是捕获型的 抛出型:抛出事件等待其他捕获型捕获比如开始事件、中间捕获事件、边界事件 捕获型:则是接收抛出型抛出的事件

中间定时事件

说明

中间定时事件是一个捕获事件，当执行到达捕获事件节点， 就会启动一个定时器。 当定时器触发（一段时间之后），流程就会沿着定时中间事件的外出节点继续执行。 可观察select * from act_ru_timer_job 此表

设计

用户下单节点完成后,会到达中间定时事件节点,同时select * from act_ru_timer_job 在这个表生成一条job记录 到达指定事件则完成此节点

相关参数设置

timeDate

在指定时间点执行 使用 ISO 8601

如：2011-03-11T12:13:14

<timerEventDefinition>
    <timeDate>2011-03-11T12:13:14</timeDate>
</timerEventDefinition>

 

timeDuration

指定定时器之前要等待多长时间， timeDuration可以设置为timerEventDefinition的子元素。 使用ISO 8601规定的格式 （由BPMN 2.0规定）。示例（等待10天）。

<timerEventDefinition>
    <timeDuration>P10D</timeDuration>
</timerEventDefinition>

 

timeCycle

指定重复执行的间隔， 可以用来定期启动流程实例，或为超时时间发送多个提醒。 timeCycle元素可以使用两种格式。第一种是 ISO 8601 标准的格式。示例（重复3次，每次间隔10小时）

<timerEventDefinition>
    <timeCycle>R3/PT10H</timeCycle>
</timerEventDefinition>

cron格式

如每月月初启动一个任务

0 0 2 1 * ?
