我在bpmn.io中設計了一個不完整的bpmn過程（請參閱下面的xml，您可以將它加載到bpmn.io的建模器中）。Camunda BPMN驗證成功，但模型不完整
在下一步我寫了一個簡單的驗證功能according to this guide。該功能也在下面。
的問題
我的問題是，有沒有拋出錯誤，儘管該模型似乎是無效的（無ENDEVENT，只是一個sequenceFlow走出去的XOR網關）。來自BPMN類的validateModel方法只是從它的內部分析器中調用相同的方法。我錯過了像之前定義方案的東西，還是我完全誤解了一個有效的bpmn的外觀以及如何驗證它？
驗證法
public String validateModel(String modelString) {
String message = "";
try {
InputStream stream = new ByteArrayInputStream(modelString.getBytes(Charset.forName("UTF-8")));
BpmnParser parser = new BpmnParser();
BpmnModelInstance modelinstance = parser.parseModelFromStream(stream);
parser.validateModel(modelinstance.getDocument());
Bpmn.validateModel(modelinstance); //does the same as above, just added for completeness
message = "Model is conform!";
} catch (Exception e) {
message = e.getMessage();
}
return message;
}
