创建一个新的springboot工程，在其pom文件,加入spring-boot-starter-data-redis依赖：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>REcevier类，它是一个普通的类，需要注入到springboot中。

public class Receiver { private static final Logger LOGGER = LoggerFactory.getLogger(Receiver.class); private CountDownLatch latch; @Autowired public Receiver(CountDownLatch latch) { this.latch = latch; } public void receiveMessage(String message) { LOGGER.info("Received <" + message + ">"); latch.countDown(); }} |

@Bean Receiver receiver(CountDownLatch latch) { return new Receiver(latch); } @Bean CountDownLatch latch() { return new CountDownLatch(1); } @Bean StringRedisTemplate template(RedisConnectionFactory connectionFactory) { return new StringRedisTemplate(connectionFactory); } |
在spring data redis中，利用redis发送一条消息和接受一条消息，需要三样东西：
上述1、3步已经完成，所以只需注入消息监听容器即可：

@Bean RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory, MessageListenerAdapter listenerAdapter) { RedisMessageListenerContainer container = new RedisMessageListenerContainer(); container.setConnectionFactory(connectionFactory); container.addMessageListener(listenerAdapter, new PatternTopic("chat")); return container; } @Bean MessageListenerAdapter listenerAdapter(Receiver receiver) { return new MessageListenerAdapter(receiver, "receiveMessage"); } |
在springboot入口的main方法：

public static void main(String[] args) throws Exception{ ApplicationContext ctx = SpringApplication.run(SpringbootRedisApplication.class, args); StringRedisTemplate template = ctx.getBean(StringRedisTemplate.class); CountDownLatch latch = ctx.getBean(CountDownLatch.class); LOGGER.info("Sending message..."); template.convertAndSend("chat", "Hello from Redis!"); latch.await(); System.exit(0); } |
先用redisTemplate发送一条消息，接收者接收到后，打印出来。启动springboot程序，控制台打印：
