java - RabbitMQ Spring死信配置不起作用

以下是我正在使用的配置。消息没有错误，从交换到队列都可以正常工作，并且侦听器可以进行转换，这很棒。我希望与错误消息一起发生的原因是，当我抛出 AmqpRejectAndDontRequeueException 时，“rabbitQueue”会将消息转发到死信交换，并最终出现在“rabbitErrorQueue”中。死信交换或队列上没有任何 Activity 。有人可以在这里看到我在做什么吗？

最佳答案

尝试添加一个显式的x-dead-letter-routing-key-否则使用与原始路由相同的密钥-展开扇出交换不需要路由密钥。
