前言：

本文基于jedis 2.9.0.jar、commons-pool2-2.4.2.jar以及json-20160810.jar

其中jedis连接池需要依赖commons-pool2包，json包用于对象实例和json字符串的相互转换

1、jedis的消息队列方法简述

1.1、发布消息方法

（其中，channel是对应消息通道，message是对应消息体）

jedis.publish(channel, message);

1.2、监听消息方法

（其中，jedisPubSub用于处理监听到的消息，channels是对应的通道）

jedis.subscribe(jedisPubSub, channels);

2、发布消息

/**	 * 从jedis连接池获取jedis操作实例	 * @return	 */	public static Jedis getJedis() {		return RedisPoolManager.getJedis();	}	/**	 * 推入消息到redis消息通道	 * 	 * @param String	 *            channel	 * @param String	 *            message	 */	public static void publish(String channel, String message) {		Jedis jedis = null;		try {			jedis = getJedis();			jedis.publish(channel, message);		} finally {			jedis.close();		}	}	/**	 * 推入消息到redis消息通道	 * 	 * @param byte[]	 *            channel	 * @param byte[]	 *            message	 */	public void publish(byte[] channel, byte[] message) {		Jedis jedis = null;		try {			jedis = getJedis();			jedis.publish(channel, message);		} finally {			jedis.close();		}	}

3、监听消息

3.1、监听消息主体方法

/**	 * 监听消息通道	 * @param jedisPubSub - 监听任务	 * @param channels - 要监听的消息通道	 */	public static void subscribe(BinaryJedisPubSub jedisPubSub, byte[]... channels) {		Jedis jedis = null;		try {			jedis = getJedis();			jedis.subscribe(jedisPubSub, channels);		} finally {			jedis.close();		}	}	/**	 * 监听消息通道	 * @param jedisPubSub - 监听任务	 * @param channels - 要监听的消息通道	 */	public static void subscribe(JedisPubSub jedisPubSub, String... channels) {		Jedis jedis = null;		try {			jedis = getJedis();			jedis.subscribe(jedisPubSub, channels);		} finally {			jedis.close();		}	}

3.2、处理监听到的消息任务

class Tasker implements Runnable {	private String[] channel = null;//监听的消息通道	private JedisPubSub jedisPubSub = null;//消息处理任务	public Tasker(JedisPubSub jedisPubSub, String ...channel) {		this.jedisPubSub = jedisPubSub;		this.channel = channel;	}	@Override	public void run() {		// 监听channel通道的消息		RedisMQ.subscribe(jedisPubSub, channel);	}}

3.3、处理监听到的消息主体类实现

package cn.eguid.livePushServer.redisManager;import java.util.Map;import org.json.JSONObject;import cc.eguid.livepush.PushManager;import redis.clients.jedis.JedisPubSub;public class RedisMQHandler extends JedisPubSub{	PushManager pushManager = null;	public RedisMQHandler(PushManager pushManager) {		super();		this.pushManager = pushManager;	}	@Override	// 接收到消息后进行分发执行	public void onMessage(String channel, String message) {		JSONObject jsonObj = new JSONObject(message);		System.out.println(channel+","+message);		if ("push".equals(channel)) {			Map
    
      map=jsonObj.toMap();			System.out.println("接收到一条推流消息，准备推流："+map);//			String appName=pushManager.push(map);			//推流完成后还需要发布一个成功消息到返回队列					} else if ("close".equals(channel)) {			String appName=jsonObj.getString("appName");			System.out.println("接收到一条关闭消息，准备关闭应用："+appName);//			pushManager.closePush(appName);		}	}}
    

4、测试消息队列发布和监听

public static void main(String[] args) throws InterruptedException {				PushManager pushManager= new PushManagerImpl();		Thread t1 = new Thread(new Tasker(new RedisMQHandler (pushManager), "push"));		Thread t2 = new Thread(new Tasker(new RedisMQHandler (pushManager), "close"));		t1.start();		t2.start();				LivePushEntity livePushInfo=new LivePushEntity();		livePushInfo.setAppName("test1");		JSONObject json=new JSONObject(livePushInfo);		publish("push",json.toString());		publish("close", json.toString());		Thread.sleep(2000);		publish("push", json.toString());		publish("close",json.toString());		Thread.sleep(2000);		publish("push", json.toString());		publish("close",json.toString());	}
