死信通道如何获取源路由？

Question

I define a DeadLetterChannel. There I change some Values and save the MessageHistory into the exchange. Now I want to insert into the Headers from the exchange the Name of the Route where the exception happend. But I don't find any way to get the name of the source route.

Did anybody can help me?

Answer 1

You can get the route id from the exchange property with the key Exchange.FAILURE_ROUTE_ID

String routeId = exchange.getProperty(Exchange.FAILURE_ROUTE_ID);
