Question

我想创建一个自定义工作流，以便由包含两个用户的组审阅文档，这两个用户应该能够并行审阅该文档。我该怎么办？

我要做的就是由一个用户审阅文档（请参阅附件代码），为了将审阅任务分配给一个组，我需要更改什么？

Answer 1

您不能将任务分配给组。但是您可以有一个任务的多个实例。

将您的审核任务定义为多实例任务。

<userTask id="reviewTask" name="Review Task" activiti:formKey="wfa:activitiReviewTaskk">
<multiInstanceLoopCharacteristics isSequential="false">
<loopDataInputRef>assigneeList</loopDataInputRef>
<inputDataItem name="assignee" />
</multiInstanceLoopCharacteristics>
...
</userTask>

要为审阅者组的每个用户创建一个实例，可以在工作流程启动时将assigneeList设置为该组中的用户列表。

您还应该定义任务在何时完成。完成了两个或更多审阅任务的实例？

<completionCondition>${nrOfCompletedInstances >= 2 }</completionCondition>

还是全部？

<completionCondition>${nrOfCompletedInstances==nrOfInstances}</completionCondition>

最后，您还应该考虑总体审查结果应该是什么。是否所有用户都必须批准该文档才能将其视为已批准？两个或更多？至少50％？一种实现上述目的的方法是，只要审阅任务的实例以批准结束就增加计数器的值，并在任务完成后检查该值。

另请参阅Multi-instance tasks和Xml representation of multi-instance tasks。

Answer 2

您可以在userTask标记内使用此属性将任务分配给组：

activiti:candidateGroups="GROUP_development"

您可以用逗号分隔的值格式添加多个组，并且每个组名必须以“ GROUP_”为前缀。

请记住，通过这种方式可以将任务转换为共享任务，这意味着完成任务的第一个用户可以完成任务。

通过激活将工作流程分配给Alfresco中的组
