flowable流程中心设计之网关(八)

简介

网关主要作用是根据条件控制,判断流向,主要分为连线，排他网关，并行网关，兼容网关，事件网关。

连线

说明

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。

排他网关

说明

排他网关好像一个人在分岔路口，只会选择一条线路前进，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

说明

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。

设计

发起人填表后,3条线上传附件，然后汇集一起提交

包含网关

说明

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。

设计

事件网关

说明

网关的每个外出顺序流都要连接到一个中间捕获事件
