配置类

生产者发送消息

import org.springframework.amqp.core.Message;
import org.springframework.amqp.core.MessagePostProcessor;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.text.SimpleDateFormat;
import java.util.Date;

@RestController
public class SendMessageController {
          
   

    @Autowired
    RabbitTemplate rabbitTemplate;

    //发送消息到正常队列
    @GetMapping("/sendDirectMessage")
    public String sendDirectMessage(@RequestParam String message) {
          
   
        
        SimpleDateFormat Dateformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println(Dateformat.format(new Date())+":发送消息");
        
        //将消息携带绑定键值：TestDirectRouting 发送到交换机TestDirectExchange
        rabbitTemplate.convertAndSend("TestDirectExchange", "TestDirectRouting", message);
        return "ok";
    }

    //发送消息到死信队列
    @GetMapping("/sendDelayMessage")
    public String sendDelayMessage(@RequestParam String message,@RequestParam(value = "delayTimes") long delayTimes) {
          
   
        
        SimpleDateFormat Dateformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println(Dateformat.format(new Date())+":发送消息");
        
        //将消息携带绑定键值：TestTtlDirectRouting 发送到交换机TestTtlDirectExchange
        rabbitTemplate.convertAndSend("TestTtlDirectExchange", "TestTtlDirectRouting", message, new MessagePostProcessor() {
          
   
            @Override
            public Message postProcessMessage(Message message) throws AmqpException {
          
   
                message.getMessageProperties().setExpiration(String.valueOf(delayTimes));
                return message;
            }
        });
        return "ok";
    }
}

消费者打印消息

import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.text.SimpleDateFormat;
import java.util.Date;


@Component
@RabbitListener(queues = "TestDirectQueue")//监听TestDirectQueue队列
public class AcceptMessageController {
          
   
    @Autowired
    RabbitTemplate rabbitTemplate;

    @RabbitHandler//执行方法
    public void cancelDirectMessage(String testMessage) {
          
   
        SimpleDateFormat Dateformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        System.out.println(Dateformat.format(new Date())+":消费者收到消息  : " + testMessage);
    }
