参考:http://spring.io/guides/gs/messaging-redis/

非常典型而简单的一个Message-Driven风格.

1.主要依赖pom.xml

<dependency><groupId>redis.clients</groupId><artifactId>jedis</artifactId><version>2.5.2</version></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId><version>2.2</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-redis</artifactId><version>1.4.1.RELEASE</version></dependency>

2.Bean配置AppConfig

@Configurationpublic class AppConfig {    @Bean    public RedisConnectionFactory redisConnectionFactory(){        JedisConnectionFactory redisConnectionFactory=new JedisConnectionFactory();        redisConnectionFactory.setHostName("192.168.1.118");        redisConnectionFactory.setUsePool(true);        return redisConnectionFactory;    }    @Bean    StringRedisTemplate template(RedisConnectionFactory connectionFactory) {        return new StringRedisTemplate(connectionFactory);    }        @Bean    public CountDownLatch latch() {        return new CountDownLatch(1);    }    @Bean    public Receiver receiver(CountDownLatch latch) {        return new Receiver(latch);    }    @Bean    public MessageListenerAdapter listenerAdapter(Receiver receiver) {        return new MessageListenerAdapter(receiver, "receiveMessage");    }    @Bean    public RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory,MessageListenerAdapter listenerAdapter) {        RedisMessageListenerContainer container = new RedisMessageListenerContainer();        container.setConnectionFactory(connectionFactory);        container.addMessageListener(listenerAdapter, new PatternTopic("chat"));        return container;    }}

3.消息接收端Receiver

public class Receiver {    private CountDownLatch latch;    @Autowired    public Receiver(CountDownLatch latch) {        this.latch = latch;    }    public void receiveMessage(String message) {        System.out.println("Received <" + message + ">");        latch.countDown();    }}

4.消息发送端Main

public class Main {    public static void main(String[] args) throws InterruptedException {        ApplicationContext ctx = new AnnotationConfigApplicationContext(AppConfig.class);        StringRedisTemplate template = ctx.getBean(StringRedisTemplate.class);        CountDownLatch latch = ctx.getBean(CountDownLatch.class);        System.out.println("Sending message...");        template.convertAndSend("chat", "Hello from Redis!");        latch.await();        System.exit(0);    }}
