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;}@Overridepublic 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<String,Object> 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());}
