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
