Springboot 整合Redis 发布订阅消息

Redis不仅可作为缓存服务器，还可用作消息队列。它的列表类型天生支持用作消息队列。如下图所示：

    implementation group: 'redis.clients', name: 'jedis', version: '2.9.0'

spring:
	  redis:
	    host: xxx
	    port: xxx
	    password: xxx
	    timeout: 10000

@Configuration
public class RedisConfig {


    @Bean
    RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,
                                            MessageListenerAdapter listenerAdapter) {
        RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        //订阅通道
        //这个container 可以添加多个 messageListener 监听多个通道
        container.addMessageListener(listenerAdapter, new PatternTopic("Notice"));
        return container;
    }

    @Bean
    MessageListenerAdapter listenerAdapter(RedisService redisSendService) {
        return new MessageListenerAdapter(redisSendService, "onMessage");
    }

}

@Service
public class RedisService implements MessageListener {

   @Override
    public void onMessage(Message message, byte[] pattern) {
        try {
             System.out.println("收到消息:"+message.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class RedisServiceTest {

    @Autowired
    private StringRedisTemplate redisTemplate;


    @Test
    public void redisSend() {
        redisTemplate.convertAndSend("Notice", "在知识的海洋里狗刨!!!");
    }

}
