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。

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。

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)。

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)。

6.2 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
