问题
Is there any functionality built in to spring-amqp that would make it easy to requeue dead letter messages? I can write code to do it but it seems like such a common use case that would fit well into the framework.
回答1:
This is outside of Spring AMQP, but you can configure a TTL on the dead letter queue and configure that queue to dead-letter back to the original queue when expired.
You can check the x-death header if you want to give up completely after some number of retry cycles.
See this answer and its question for more information.
