简单mpush长连接实现

1.mpush服务搭建，根据官网http://mpush.mydoc.io/?t=134336服务部署搭建redis服务，zk服务

2.服务端sdk接入，根据文档配置，发送send实现如下

public class MpushUtils {

    private static MpushUtils mpushUtils;

    static Logger log = LoggerFactory.getLogger(MpushUtils.class);
    private final static PushSender sender = PushSender.create();

    public static void send(String userId, PushMsg msg, String msgId) throws Exception {
        FutureTask future = null;

        if (!sender.isRunning()) {
            sender.start();
        }

        msg.setMsgId("msgId" + msgId);
        PushContext context = PushContext.build(msg)
                .setAckModel(AckModel.AUTO_ACK)
                .setUserId(userId)
                //.setUserIds(userIds)
                .setBroadcast(false)
                .setTimeout(2000)
                .setCallback(new PushCallback() {
                    //推送成功后的回调
                    @Override
                    public void onResult(PushResult result) {
                        log.info("\n\n" + result);
                    }
                });
        future = sender.send(context);
        log.info("推送结果===========>" + future.toString());

    }

3.MPushClient(Java)是一个java写的客户端具体接入mpush服务如下

public class MpushUtil {

    private static final Logger logger = LogManager.getLogger(MpushUtil.class);
    private static final String publicKey = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCghPCWCobG8nTD24juwSVataW7iViRxcTkey/B792VZEhuHjQvA3cAJgx2Lv8GnX8NIoShZtoCg3Cx6ecs+VEPD2fBcg2L4JK7xldGpOJ3ONEAyVsLOttXZtNXvyDZRijiErQALMTorcgi79M5uVX9/jMv2Ggb2XAeZhlLD28fHwIDAQAB";

    public static Client client;

    public static void connectAndbind(String userId) {
            String serverHost = "192.168.80.182";//部署好的mpush服务ip
   
        String cacheDir = MpushUtil.class.getResource("/").getFile();
        ScheduledExecutorService scheduledExecutor = Executors.newSingleThreadScheduledExecutor();
        ClientListener listener = new L(scheduledExecutor);
        client = ClientConfig
                .build()
                .setPublicKey(publicKey)
                //.setAllotServer(allocServer) //未使用alloc服务
                .setServerHost(serverHost)
                .setServerPort(3000) //mpush服务端口号默认是3000
                .setDeviceId("deviceId")
                .setUserId(userId)
                .setSessionStorageDir(cacheDir)
                .setLogger(new DefaultLogger())
                .setLogEnabled(true)
                .setEnableHttpProxy(true)
                .setClientListener(listener)
                .create();
        client.start();

    }

    public static class L implements ClientListener {
        private final ScheduledExecutorService scheduledExecutor;
        boolean flag = true;

        public L(ScheduledExecutorService scheduledExecutor) {
            this.scheduledExecutor = scheduledExecutor;
        }

        @Override
        public void onConnected(Client client) {
            System.out.println("================>connected");
            flag = true;
        }

        @Override
        public void onDisConnected(Client client) {
            System.out.println("================>disconnected");
            flag = false;
        }

        @Override
        public void onHandshakeOk(final Client client, final int heartbeat) {

            System.out.println("=================>handshakeOk");

            System.out.println();
            scheduledExecutor.scheduleAtFixedRate(new Runnable() {
                @Override
                public void run() {
                    client.healthCheck();
                }
            }, 10, 10, TimeUnit.SECONDS);

            //client.push(PushContext.build("test"));

        }

        @Override
        public void onKickUser(String deviceId, String userId) {
            System.out.println("==============================>onkickUser");
        }

        /**
         * 方法名称：

         * 概要说明：推送消息监听

         * 
         * @see com.mpush.api.ClientListener#onReceivePush(com.mpush.api.Client, byte[])
         */
        @Override
        public void onReceivePush(Client client, byte[] content) {
            System.out.println("======================>onReceivePush");
           //用于监听后台服务推送信息
          
        }

    }

    public static void main(String[] args) {
        connectAndbind("12345");
      //client.stop();//关闭进程后要将长连接关闭不然可能导致心跳重连的时候出错
    }

}

注意：在客户端启动连接的时候本人是报错
PushSender推送建立连接超时
错误如下:io.netty.channel.ConnectionTimeOutException:connection timed out: /xxx.xxx.xxx.xxx:3001

解决方式:
a.) 首先检查ip是否正确 telnet xxx.xxx.xxx.xxx 3001是否通
b.) 如果ip不正确增加配置mp.net.local-ip="指定具体的ip"
解决方法是在搭建的mpush服务中修改
mp.net.local-ip="192.168.80.182" //本地ip, 默认取第一个网卡的本地IP
