本文详细介绍了如何使用RabbitMQ实现不同模式的消息传递，包括Direct、Topic、Fanout和Header模式。通过代码示例，展示了消息发送、接收的具体实现，以及如何配置交换机、队列和绑定。

1、交换及和队列的封装：

@Configuration
public class MQConfig {
   
   public static final String MIAOSHA_QUEUE = "miaosha.queue";
   public static final String QUEUE = "queue";
   public static final String TOPIC_QUEUE1 = "topic.queue1";
   public static final String TOPIC_QUEUE2 = "topic.queue2";
   public static final String HEADER_QUEUE = "header.queue";
   public static final String TOPIC_EXCHANGE = "topicExchage";
   public static final String FANOUT_EXCHANGE = "fanoutxchage";
   public static final String HEADERS_EXCHANGE = "headersExchage";
   
   /**
    * Direct模式 交换机Exchange
    * */
   @Bean
   public Queue queue() {
      return new Queue(QUEUE, true);
   }
   
   /**
    * Topic模式 交换机Exchange
    * */
   @Bean
   public Queue topicQueue1() {
      return new Queue(TOPIC_QUEUE1, true);
   }
   @Bean
   public Queue topicQueue2() {
      return new Queue(TOPIC_QUEUE2, true);
   }
   @Bean
   public TopicExchange topicExchage(){
      return new TopicExchange(TOPIC_EXCHANGE);
   }
   @Bean
   public Binding topicBinding1() {
      return BindingBuilder.bind(topicQueue1()).to(topicExchage()).with("topic.key1");
   }
   @Bean
   public Binding topicBinding2() {
      return BindingBuilder.bind(topicQueue2()).to(topicExchage()).with("topic.#");
   }
   /**
    * Fanout模式 交换机Exchange
    * */
   @Bean
   public FanoutExchange fanoutExchage(){
      return new FanoutExchange(FANOUT_EXCHANGE);
   }
   @Bean
   public Binding FanoutBinding1() {
      return BindingBuilder.bind(topicQueue1()).to(fanoutExchage());
   }
   @Bean
   public Binding FanoutBinding2() {
      return BindingBuilder.bind(topicQueue2()).to(fanoutExchage());
   }
   /**
    * Header模式 交换机Exchange
    * */
   @Bean
   public HeadersExchange headersExchage(){
      return new HeadersExchange(HEADERS_EXCHANGE);
   }
   @Bean
   public Queue headerQueue1() {
      return new Queue(HEADER_QUEUE, true);
   }
   @Bean
   public Binding headerBinding() {
      Map<String, Object> map = new HashMap<String, Object>();
      map.put("header1", "value1");
      map.put("header2", "value2");
      return BindingBuilder.bind(headerQueue1()).to(headersExchage()).whereAll(map).match();
   }
   
   
}

2、发送

@Service
public class MQSender {

   private static Logger log = LoggerFactory.getLogger(MQSender.class);
   
   @Autowired
   AmqpTemplate amqpTemplate ;
   
   public void sendMiaoshaMessage(MiaoshaMessage mm) {
      String msg = RedisService.beanToString(mm);
      log.info("send message:"+msg);
      amqpTemplate.convertAndSend(MQConfig.MIAOSHA_QUEUE, msg);
   }
   
   public void send(Object message) {
      String msg = RedisService.beanToString(message);
      log.info("send message:"+msg);
      amqpTemplate.convertAndSend(MQConfig.QUEUE, msg);
   }

   public void sendTopic(Object message) {
      String msg = RedisService.beanToString(message);
      log.info("send topic message:"+msg);
      amqpTemplate.convertAndSend(MQConfig.TOPIC_EXCHANGE, "topic.key1", msg+"1");
      amqpTemplate.convertAndSend(MQConfig.TOPIC_EXCHANGE, "topic.key2", msg+"2");
   }

   public void sendFanout(Object message) {
      String msg = RedisService.beanToString(message);
      log.info("send fanout message:"+msg);
      amqpTemplate.convertAndSend(MQConfig.FANOUT_EXCHANGE, "", msg);
   }

   public void sendHeader(Object message) {
      String msg = RedisService.beanToString(message);
      log.info("send fanout message:"+msg);
      MessageProperties properties = new MessageProperties();
      properties.setHeader("header1", "value1");
      properties.setHeader("header2", "value2");
      Message obj = new Message(msg.getBytes(), properties);
      amqpTemplate.convertAndSend(MQConfig.HEADERS_EXCHANGE, "", obj);
   }
   
}

3、接收

@Service
public class MQReceiver {

      private static Logger log = LoggerFactory.getLogger(MQReceiver.class);
      
      @Autowired
      RedisService redisService;
      
      @Autowired
      GoodsService goodsService;
      
      @Autowired
      OrderService orderService;
      
      @Autowired
      MiaoshaService miaoshaService;
      
      @RabbitListener(queues=MQConfig.MIAOSHA_QUEUE)
      public void receive(String message) {
         log.info("receive message:"+message);
         MiaoshaMessage mm  = RedisService.stringToBean(message, MiaoshaMessage.class);
         MiaoshaUser user = mm.getUser();
         long goodsId = mm.getGoodsId();
         
         GoodsVo goods = goodsService.getGoodsVoByGoodsId(goodsId);
          int stock = goods.getStockCount();
          if(stock <= 0) {
             return;
          }
          //判断是否已经秒杀到了
          MiaoshaOrder order = orderService.getMiaoshaOrderByUserIdGoodsId(user.getId(), goodsId);
          if(order != null) {
             return;
          }
          //减库存 下订单 写入秒杀订单
          miaoshaService.miaosha(user, goods);
      }
   
      @RabbitListener(queues=MQConfig.QUEUE)
      public void receive(String message) {
         log.info("receive message:"+message);
      }

      @RabbitListener(queues=MQConfig.TOPIC_QUEUE1)
      public void receiveTopic1(String message) {
         log.info(" topic  queue1 message:"+message);
      }

      @RabbitListener(queues=MQConfig.TOPIC_QUEUE2)
      public void receiveTopic2(String message) {
         log.info(" topic  queue2 message:"+message);
      }

      @RabbitListener(queues=MQConfig.HEADER_QUEUE)
      public void receiveHeaderQueue(byte[] message) {
         log.info(" header  queue message:"+new String(message));
      }

      
}
