java - Mule: knowing what component/endpoint threw an exception with default catch exception

Question

I have a default catch exception strategy for my entire flow/subflows. However, I'd like to be able to tell what component/endpoint threw an exception so I can try to restart the flow at that point (I have yet to figure out how to do that as well.)

Is there any easy way to tell what component/endpoint threw the exception, and be able to tell if it was in a foreach, and at what point (by looking at the "counter" variable.)

Thanks!

您可以在流程开始时设置一个变量，如下所示：

<set-variable variableName="flowName" value="Your_flow_name"/>

#[flowName]并像在您的异常策略中一样获取流名称。

编辑：

要触发一个流，创建一个 java 组件实现Callable接口，从contextgetMuleClient和使用sendordispatch方法将有效负载发送到流。Send导致 MuleClient 等待响应而dispatch没有。
