Activiti中网关分为连线,排他网关,并行网关,兼容网关,事件网关,接下来我们分别介绍他们的使用方式。
*后台服务基于Springboot2 + Activiti6,整合文章请参考:https://blog.csdn.net/yy756127197/article/details/101211510 不需要流程设计器就排除3,4步骤 *
连线就是可以设置多条线路,如果有多条连线符合条件,那就选择第一条在流程文件中出现的连线,如果没有符合条件的,就是用默认线路。

并行网关用于表述流程的并发,并行网关可以让一个执行流变成多个同时进行的并发执行流,也可以让多个执行流合并为一个执行流,因此并行网关会有两种行为,分岔和合并。

兼容网关就好像排他网关和并行网关的结合体,与排他网关不同的是,兼容网关可以创建多条执行流,换言之,如果多个条件成立,那么此时可以将它看做并行网关,而排他网关,多个条件成立时,只会选择第一个定义的顺序流。

运行deploy(), start()
运行queryTask()
运行completeTask2(),设置参数days==7
当流程经过事件网关时,如果某一事件先触发,流程就往这一事件所处方向执行。
不太常用,感兴趣的额外看下。
