java - 如何使用 Activiti 将注释添加到工作流程

标签 java xml workflow activiti bpmn

我正在尝试使用 Java 和 Activiti 可视化现有工作流程。

我在后台使用自己的工作流引擎，但它确实不清楚，因为它只是以表格形式呈现工作流数据。这就是为什么我想将表中的数据转换为标准 BPMN 2.0 形式。因此使用包org.activiti.bpmn.model。不同的任务由UserTask类创建，SequenceFlows按预期生成，布局由Activiti的自动bpmn布局功能设计。我现在的问题是用户任务的不同先决条件和影响。在某些情况下，数量太多，以至于仅将它们添加为序列流的名称会导致文本过多。我的想法只是向用户任务添加一个节点，在其中我可以添加一个包含这些内容的字符串，但我没有找到解决此问题的合适对象。我已经尝试将 Message 对象与 MessageFlow 对象结合使用，但它没有像我希望的那样工作。

创建工作流程后，将其保存为 XML 文件，并检查转换后的工作流程的外观，将其上传到 bpmn.io(目前包括一个消息对象，如果 XML 文件上传到 bpmn.io，则不会显示该消息对象) ):

最佳答案

为什么不在 Activity 或序列流中使用文档字段。 在 XML 中，它看起来像这样:

<sequenceFlow id="flow4" sourceRef="usertask1" targetRef="exclusivegateway1">
  <documentation>This is some element documentation.</documentation>
</sequenceFlow>

然后在 BPMN 编辑器中它将显示为文档。 您正在进行的项目非常有趣。
