java - RabbitMQ Spring 死信配置不起作用

Question

下面是我正在使用的配置。没有错误的消息，从交换到队列工作正常，转换由监听器接收，非常棒。我希望发生错误消息的是，当我抛出一个AmqpRejectAndDontRequeueException时，“rabbitQueue”会将消息转发到它的死信交换并最终出现在“rabbitErrorQueue”中”不过，死信交换或队列上没有任何 Activity 。任何人都可以看到我在这里做错了什么吗？

尝试添加显式 x-dead-letter-routing-key - 否则使用与原始路由相同的 key - 扇出交换不需要路由 key 。
