1. 首先需要一个消息监听器类
[html] view plain copy package com.sogou.baike.testimport.testSubscribe; import redis.clients.jedis.JedisPubSub; /** * Created by denglinjie on 2016/6/29. */ public class RedisMsgPubSubListener extends JedisPubSub { @Override public void unsubscribe() { super.unsubscribe(); } @Override public void unsubscribe(String... channels) { super.unsubscribe(channels); } @Override public void subscribe(String... channels) { super.subscribe(channels); } @Override public void psubscribe(String... patterns) { super.psubscribe(patterns); } @Override public void punsubscribe() { super.punsubscribe(); } @Override public void punsubscribe(String... patterns) { super.punsubscribe(patterns); } @Override public void onMessage(String channel, String message) { System.out.println("channel:" + channel + "receives message :" + message); this.unsubscribe(); } @Override public void onPMessage(String pattern, String channel, String message) { } @Override public void onSubscribe(String channel, int subscribedChannels) { System.out.println("channel:" + channel + "is been subscribed:" + subscribedChannels); } @Override public void onPUnsubscribe(String pattern, int subscribedChannels) { } @Override public void onPSubscribe(String pattern, int subscribedChannels) { } @Override public void onUnsubscribe(String channel, int subscribedChannels) { System.out.println("channel:" + channel + "is been unsubscribed:" + subscribedChannels); } } 该类需要继承 JedisPubSub ，并实现其抽象方法，通过方法的名称很清楚的看出来，这个监听器是用来订阅一个频道，在订阅该频道，取消订阅，收到消息等状态会对应调用相关的方法
2. 订阅测试类
[html] view plain copy public class TestSubscribe { @Test public void testSubscribe() throws Exception{ Jedis jedis = new Jedis("localhost"); RedisMsgPubSubListener listener = new RedisMsgPubSubListener(); jedis.subscribe(listener, "redisChatTest"); //other code } } 该类实现对频道redisChatTest的订阅监听，频道的订阅，取消订阅，收到消息都会调用listener对象的对应方法
注意：subscribe是一个阻塞的方法，在取消订阅该频道前，会一直阻塞在这，只有当取消了订阅才会执行下面的other code，参考上面代码，我在onMessage里面收到消息后，调用了this.unsubscribe(); 来取消订阅，这样才会执行后面的other code
3. 发布消息测试类
[html] view plain copy Public class TestPublish { @Test public void testPublish() throws Exception{ Jedis jedis = new Jedis("localhost"); jedis.publish("redisChatTest", "我是天才"); Thread.sleep(5000); jedis.publish("redisChatTest", "我牛逼"); Thread.sleep(5000); jedis.publish("redisChatTest", "哈哈"); } }
这个类向频道redisChatTest发布消息，第二步因为订阅了该频道，所以会收到该消息。
