SpringAMQP开启“可靠性”机制

延迟队列设计

在开发过程中涉及到延迟队列的应用，例如订单生成后有30分钟的付款时间，注册是有60秒的邮件或者短信的发送读取时间等。
常规使用rabbitmq设计延迟队列有两种方式

  1. 使用创建一个延迟队列阻塞消息
  2. 使用延迟队列插件

生产者发送信息

    @Override
    public void delaySendMessage() {
        String uuid = UUID.randomUUID().toString();
        CorrelationData data = new CorrelationData(uuid);
        String msg = "hello delay";
        int delayTime =5000;

        rabbitTemplate.convertAndSend("normal_exchange_test", "normal_routing_test", msg,

                    return p;
                });

        log.debug("发送一条消息{},当前时间:{},延迟{}秒", msg, new Date(), delayTime / 1000);
    }
}

消费者消费

   @RabbitListener(queues = "dlx_queue_test")
    public void delayConsume(Message message){
      log.debug("消费者消费信息:{},当前时间:{}",message.getBody(),new Date());
    }
