java - Camunda java相当于将所有变量传递给 Activity

Question

我有代码可以创建这样的虚拟模型

BpmnModelInstance modelInstance = Bpmn.createExecutableProcess("onelongmodel")
                .name("onelongmodel")
                .startEvent()               
                .camundaAsyncBefore()
                .callActivity("oneactivity").name("oneactivity").calledElement("oneactivity")
                .endEvent()
                .done();

我想将所有变量传入和传出 Activity ，我可以通过添加到 bpmn 文件来实现

  <extensionElements>
       <camunda:in variables="all" />
       <camunda:out variables="all" />
    </extensionElements>

我想用java来完成这一步。如何更改上面的 java 代码以添加此选项？

我想这就是你要找的

private void deployProcess(String eventName) {

 BpmnModelInstance modelInstance = Bpmn.createExecutableProcess(PROCESS_ID)
  .startEvent()
  .userTask(USER_TASK_ID)
  .endEvent()
  .done();

 ExtensionElements extensionElements = modelInstance.newInstance(ExtensionElements.class);

 ModelElementInstance taskListener = extensionElements.addExtensionElement(CAMUNDA_NS, "taskListener");

 taskListener.setAttributeValueNs(CAMUNDA_NS, "class", ModelExecutionContextTaskListener.class.getName());

 taskListener.setAttributeValueNs(CAMUNDA_NS, "event", eventName);

 UserTask userTask = modelInstance.getModelElementById(USER_TASK_ID);

 userTask.setExtensionElements(extensionElements);

 deploymentId = repositoryService.createDeployment().addModelInstance("process.bpmn", modelInstance).deploy().getId();
}
