ActiveMQ代理关闭。 生产者异步发送消息。 如何对生产者发送的邮件执行重新传递？ 如何使用死信队列

Question

I have a scenario where my ActiveMQ broker is down. My producer is trying to send messages to this broker in an asynchronous manner ( connectionfactory.setUseAsyncSend(true) ). Since broker is down no messages reach the broker. I want to perform redelivery for this failed messages, and put them onto a deadletter queue if a fixed number of redelivery attempts are made. If possible send these messages from deadletter queue once the broker is up. I am using JMSTemplate to send messages and code is in Java.

Any help is really appreciated.

If your broker is down, you won't be able to write to the DLQ, because that's also located on the broker!

The best bet you have is to just handle this failure scenario properly, and do a proper stop until your health check deems the broker is back up. The docs aren't so clear about it, but it seems like async sending is ideal when you can tolerate some message loss; it may be async sends don't at first give you an Exception if something goes wrong, so you might need to use synchronous if you can't tolerate message loss.
