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
