Payload of the ErrorMessage in ErrorChannel does not contain Kafka Topic

Question

Following on from this question Messages DO NOT appear in the Spring Integration (Kafka) ErrorChannel when Broker is unavailable

I now have it working nicely and the spring integration Kafka default ErrorChannel is being called when there is an error state, with the associated ErrorMessage. My problem now, is that I need to determine the Topic of the message and there is no way to do this, other than including it in the Message Header .

What is the best approach for doing this - shall I create a special errorChannel that is associated with one and only one Topic?

Answer 1

The payload.failedMessage property of the error message is the original message that arrived at the adapter.

You could use a <header-enricher /> upstream of the adapter, to set header kafka_topic to the topic. That is the default mechanism used if no topic or topic-expression is configured on the adapter.
