创建两个队列QA和QB，两者队列TTL分别设置为10S和40S，然后在创建一个交换机X和死信交换机Y，它们的类型都是direct，创建一个死信队列QD，它们的绑定关系如下

监听
@Slf4j @Component public class Consumer { @RabbitListener(queues = "QD") public void receiveD(Message message, Channel channel) { System.out.println("*****************************"); String s = new String(message.getBody()); log.info("当前时间{}，死信队列接收到消息---->{}",new Date(),s); System.out.println("*****************************"); } }
