#### ExclusiveGateway 排它网关 ####

所谓网关就是条件分支语句if() else if () ，排它网关会执行所有条件找到一个为true的执行，如果有多个条件为true那么会执行优先定义的（Id较小的那个UserTask），如果条件都为false则抛出异常。  
排它网关和直接在连线上设置条件的区别：

*  条件分支不满条件抛异常，如果都满足都执行。
 *  排它网关不满足条件抛异常，如果都满足只执行Id较小的任务（即先绘制的任务）。

if(day < 3) {
        
    
    } else if (day > 3) {
        
    
    } else {
        
    	throw new Exception();
        //上一讲的if条件判断不满足的情况下和排它网关条件不满足的情况下报错信息是一样的
        //org.activiti.engine.ActivitiException: 
        //No outgoing sequence flow of element 'sid-A9E25324-46EC-443E-B561-E582BC24B159' 
        //could be selected for continuing the process
    }

*  day大于等于3天走部门经理审批，大于小于3天直接走人事审批。
 *  修改条件，分别改为day>=3和day>=2，传值day=3，抛异常ActivitiException。

#### ParallelGateway 并行网关 ####

并行网关没有条件，写了条件也会被忽略，【全部都会执行，这里可以通过在人事审批、CTO审批上添加监听器，看监听器会发现全部执行】，前面做fork分支，后面做join汇聚。

if(true){
        
    	// UserTask
    }
    
    if(true){
        
    	// UserTask
    }

![image.png][image.png 1]当【经理审批】完接下来就会同时插入两条任务(人事审批、CTO审批)，两个经理审核完后就进入【CEO审批】。

#### InclusiveGateway 包含网关 ####

包含网关：是同时包括ExclusiveGateway 排它网关和ParallelGateway 并行网关，如果你在连线上写条件就是排它网关，如果没写条件就是ParallelGateway 并行网关。
