spring-boot. 结合redis 实现消息队列

• 导入依赖jar包

          <!-- redis 配置信息-->
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-data-redis</artifactId>
          </dependency>

• 实现消息监听接口 MessageListener\重写 onMessage方法

  
  /**
   * @author haizhuangbu
   * @date 2024/3/31 11:30
   * @mark UserInfoRegisterTopicListen
   */
  @Component
  @Slf4j
  public class UserInfoRegisterTopicListen implements MessageListener {
  
      @Autowired
      private RedisTemplate<String, String> redisTemplate;
  
      @Override
      public void onMessage(Message message, byte[] bytes) {
          log.info("接收到redis消息队列消息 : {}", message.toString());
      }
  }

• 绑定 topic 与 监听器

  @Configuration
  public class RedisTopicQueueConfig {
  
      @Autowired
      private UserInfoRegisterTopicListen userInfoRegisterTopicListen;
  
  
      /**
       * @param connectionFactory 连接工厂
       * @return redis 监听容器
       */
      @Bean
      public RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory) {
          RedisMessageListenerContainer redisMessageListenerContainer = new RedisMessageListenerContainer();
          redisMessageListenerContainer.setConnectionFactory(connectionFactory); // 连接工厂
          redisMessageListenerContainer
                  // 配置适配器与对应消息队列信息
                  .addMessageListener(new MessageListenerAdapter(userInfoRegisterTopicListen, MessageListenerAdapter.ORIGINAL_DEFAULT_LISTENER_METHOD),
                          new ChannelTopic(RedisTopicQueueEnum.USER_REGISTER.getTopic()));
          return redisMessageListenerContainer;
      }
  
  }
  

• 测试

• 代码测试

  redisTemplate.convertAndSend("userRegister", String.format("用户 %s 注册失败", userDto.getUsername()));
  

• 消息消费成功
