我创建了流程引擎、存储库服务、运行时服务并部署了 BPMN 工作流程。我还创建了一个 Process 实例并能够启动它。问题是，当我尝试使用“deleteProcessInstance”方法挂起或删除流程实例时，我收到一条错误消息，指出找不到 ProcessInstanceId！PS：我在某处了解到BPMN中的processId在Activiti中被视为processKey。
代码：
public void startProcess(String processDefinitionKey)
{
ListenerClass.processInstance=ListenerClass.runtimeService.startProcessInstanceByKey(processDefinitionKey);
}
public void deleteProcess(String processInstanceId)
{
System.out.println("Stopping Process instance id " +processInstanceId);
ListenerClass.runtimeService.deleteProcessInstance(processInstanceId, "Ok");
}
在上面的代码中，在启动流程实例时，我传递了BPMN.xml文件的“Process Id”。（这意味着BPMN.xml的processId = Activiti的processInstanceKey）
我的 BPMN.xml：
