AmqpItemReader和死信队列

Question

I'm trying to implement a job that reads messages from a queue and move them to dead letter when an error occurs. I've tried to use a transacted channel but it always requeue the message.

Is there any automatic way to do that with Spring Batch when an exception is thrown?

Answer 1

Please, refer to Spring AMQP about Dead Lettering .

There is RejectAndDontRequeueRecoverer which you can inject into the RabbitTemplate for the AmqpItemReader . So, all those .receive() will be wrapped with the retry advice and in case of exhausting the message will be rejected to the configured DLX.
