如何使用Activiti將註釋添加到工作流程

我正在嘗試使用Java和Activiti可視化現有工作流程。如何使用Activiti將註釋添加到工作流程

我在後臺使用自己的工作流引擎，但它真的不清楚，因爲它只是以表格形式呈現工作流數據。這就是爲什麼我想將表格中的數據轉換爲標準BPMN 2.0表單的原因。因此使用包org.activiti.bpmn.model。不同的任務由UserTask類創建，SequenceFlows按預期生成，並且佈局由Activiti的自動bpmn佈局功能設計。我現在的問題是不同的前提條件和用戶任務的影響。在某些情況下，有太多的文本只是將它們添加爲序列流的名稱。我的想法只是添加一個節點到用戶任務，我可以添加一個包含這些東西的字符串，但我沒有找到解決此問題的適合對象。我已經嘗試了Message對象與MessageFlow對象的結合，但它並沒有像我希望的那樣工作。

創建工作流程後，它被保存爲XML文件，並檢查轉換後的工作流程是如何在bpmn.io上載的（此時包括如果XML文件以bpmn上傳時未顯示的Message對象。 io）：

爲什麼不在活動或順序流中使用文檔字段。 在XML，它看起來像這樣：

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

然後在BPMN編輯器將顯示爲文檔。 你真的很有趣的項目。

我曾嘗試這種方式和XML的處理部分包括描述但我已經設置爲文檔中的文本未在圖中示出。 我認爲最好使用的對象是TextAnnotation。但是我有同樣的問題。我通過addAtrifact（）將TextAnnotation附加到流程實例。但是提供佈局信息的XML的底部不包含關於該對象的任何信息，因此它也不會顯示在圖中。 – Sasa

因此，現在我知道我需要一個將UserTask與TextAnnotation鏈接起來的關聯，但是當執行BpmnAutoLayout時我會得到一個NPE。失敗的方法是generateAssociationDiagramInterchangeElements（）。在執行getState（Edge）時，該方法以某種方式接收空值。 – Sasa
