           Activiti结束事件（End Event）

    曾经，黑夜多么漫长，八月雨扰眠，缘何？

    1       前言：

    Activiti工作流始于开始任务，止于结束任务。结束事件标志着（子）流程的（分支的）结束。结束事件总是抛出（型）事件。这意味着当流程执行到达结束事件时，会抛出一个结果。结果的类型由事件内部的黑色图标描绘。在XML表示中，类型由子元素声明给出。流程终结又可以分为4种情况：空结束任务、错误结束任务、取消结束任务、终结任务，其中空结束任务是最常见的结束任务。

    2       结束任务的类型：

    1）空结束任务（none end event）

    2）错误结束事件（error end event）

    3）取消结束任务（terminate end event）

    4）终结任务（Cancel end event）

    3       空结束任务（none end event）

    空结束任务是最常见的一种结束任务，也是最简单的一种结束任务，只要把结束任务置于流程的最后节点，流程实例运行到该节点的时候，流程引擎就会结束该流程实例。并没有太多复杂的技术。所以不作太多的介绍。空事件的XML表示格式，为普通结束事件声明，没有任何子元素（其它种类的结束事件都有子元素，用于声明其类型）。

    3.1   流程实例图标：

    图3-1 空结束事件图标

    3.2   代码：

    1 <endEvent id="end" name="my end event" />

    4       错误结束事件（error end event）

    错误结束事件会在流程到达错误结束事件的时候抛出错误，并结束当前的流程分支。错误可以使用使用匹配的错误边界中间事件 intermediate boundary error event 捕获。如果找不到匹配的错误边界事件，将会抛出异常。

    4.1   流程实例图标：

    错误结束事件就是自流程或者流程实例的错误结束事件抛出一个bpmn错误。然后被工作流的错误边界事件获取。

    图4-1 错误结束事件图标

    错误结束事件，表示为结束事件，加上errorEventDefinition子元素：

    1 <endEvent id="myErrorEndEvent">
2 <errorEventDefinition errorRef="myError" />
3 </endEvent>

    errorRef属性可以引用在流程外定义的error元素：

    1 <error id="myError" errorCode="123" />
2 ...
3 <process id="myProcess">
4 ...

    error的errorCode用于查找匹配的错误捕获边界事件。如果errorRef不匹配任何已定义的error，则该errorRef会用做errorCode的快捷方式。这个快捷方式是Activiti特有的。下面的代码片段在功能上是相同的。

    1 <error id="myError" errorCode="error123" />
2 ...
3 <process id="myProcess">
4 ...
5 <endEvent id="myErrorEndEvent">
6 <errorEventDefinition errorRef="myError" />
7 </endEvent>
8 ...

    与下面的功能相同

    1 <endEvent id="myErrorEndEvent">
2 <errorEventDefinition errorRef="error123" />
3 </endEvent>

    请注意errorRef必须遵从BPMN 2.0概要（schema），且必须是合法的QName。

     

    4.2   流程图设计

    流程图设计一个子流程，然后子流程里面有一个错误结束事件。外面的错误捕获边界任务就会捕获异常。捕获了异常后，由于是错误边界先去捕获异常，所以捕获错误事件分支会先执行，然后结束。正常结束事件节点所在的分支不会执行。

    4.5.4     扩展1

    下面我们改动一下流程，更清晰的看看这个工作的原理是怎么样的。

    这一次我们是把错误事件的指向正常结束事件后面去了，可以看到，后面是正常执行的。

    图4-4 错误结束事件运行结果

    4.5.5     扩展2

    再来改一下流程，可以看出，错误捕获边界是达到了终止主流程的效果的。主流程被中断了。不过错误捕获边界是否有终止事件，主流程都不会被继续往下执行。

    图4-6 错误结束事件运行结果

     

    5       取消结束任务（terminate end event）

    当到达终止结束事件时，当前的流程实例或子流程会被终止。概念上说，当执行到达终止结束事件时，会判断第一个范围 scope（流程或子流程）并终止它。请注意在BPMN 2.0中，子流程可以是嵌入式子流程，调用活动，事件子流程，或事务子流程。有一条通用规则：当存在多实例的调用过程或嵌入式子流程时，只会终止一个实例，其他的实例与流程实例不会受影响。可以添加一个可选属性terminateAll。当其为true时，无论该终止结束事件在流程定义中的位置，也无论它是否在子流程（甚至是嵌套子流程）中，都会终止（根）流程实例。

    5.1   流程实例图标：

     

    图5-1 取消结束事件图标

    终止结束事件，表示为结束事件，加上terminateEventDefinition子元素。
    请注意terminateAll属性是可选的（默认为false）。

    1 <endEvent id="myEndEvent >
2 <terminateEventDefinition activiti:terminateAll="true"></terminateEventDefinition>
3 </endEvent>

    5.2   流程图设计

    注意，这个流程的终止事件并没有设置成终止全部，可以看到，全部任务节点都被执行了。

    6       终结任务（Cancel end event）

    取消结束事件，只能与bpmn事务子流程（bpmn transaction subprocess）一起使用。当到达取消结束事件时，会抛出取消事件，且必须由取消边界事件（cancel boundary event）捕获。之后这个取消边界事件将取消事务，并触发补偿（compensation）。

    6.1   流程实例图标：

    图6-1 终结事件图标

    6.2   流程图设计

    注意，子流程必须是事务子流程，否则会抛异常。在这里可以看到，主流程是被终止的
