排他网关(也叫异或(XOR)网关,或叫基于数据的排他网关),用来在流程中实现决策。 当流程执行到这个网关,所有分支都会判断条件是否为true,如果为 true 则执行该分支,
注意,排他网关只会选择一个为 true 的分支执行。(即使有两个分支条件都为 true,排他网关也会只选择一条分支去执行)
不使用排他网关也可以实现分支:
上图中,在连线的condition条件上设置分支条件;
缺点:如果条件都不满足,不使用排他网关,流程就结束了(是异常结束);
如果使用排他网关决定分支的走向:
如果从网关出去的线所有条件都不满足则系统抛出org.activiti.engine.ActivitiException异常;
说明:经过排他网关必须要有一条且只有一条分支走;
