之前使用做项目使用到实时推送的技术，websocket需要ie9，tomcat7，jdk7以上，兼容性不够好，因此转而使用了netty-socketio，在git上的项目地址。使用maven添加netty的jar包

<dependency>     <groupId>com.corundumstudio.socketio</groupId>     <artifactId>netty-socketio</artifactId>     <version>1.7.7</version></dependency>

客户端使用socket.io，首先启动server，推送消息时服务端获取客户端，向客户端发送消息。客户端接收消息后刷新页面数据。

import com.corundumstudio.socketio.Configuration;import com.corundumstudio.socketio.SocketIOClient;import com.corundumstudio.socketio.SocketIOServer;import com.corundumstudio.socketio.listener.ConnectListener;import com.yinhai.jiankong.util.MonitorConfigUtil;import org.springframework.stereotype.Service;import java.util.Collection;import java.util.HashMap;import java.util.List;import java.util.Map;/** * Created by Administrator on 2017/5/18. */@Service("socketIoService")public class SocketIoService {    static SocketIOServer server;    static Map<String,SocketIOClient> clientsMap  = new HashMap<String, SocketIOClient>();    public void startServer()throws InterruptedException{        Configuration config = new Configuration();        //服务器主机ip        String hostName = MonitorConfigUtil.getProperties("socketHostName");        config.setHostname(hostName);        //端口        int socketPort = Integer.parseInt(MonitorConfigUtil.getProperties("socketPort"));        config.setPort(socketPort);        config.setMaxFramePayloadLength(1024 * 1024);        config.setMaxHttpContentLength(1024 * 1024);        server = new SocketIOServer(config);        //添加客户端连接事件        server.addConnectListener(new ConnectListener() {            @Override            public void onConnect(SocketIOClient client) {                String sa = client.getRemoteAddress().toString();                String clientIp = sa.substring(1,sa.indexOf(":"));//获取设备ip                /*System.out.println(clientIp+"-------------------------"+"客户端已连接");*/                Map params = client.getHandshakeData().getUrlParams();                //获取客户端连接的uuid参数                Object object = params.get("uuid");                String uuid = "";                if(object != null){                    uuid = ((List<String>)object).get(0);                    //将uuid和连接客户端对象进行绑定                    clientsMap.put(uuid,client);                }                //给客户端发送消息                client.sendEvent("connect_msg",clientIp+"客户端你好，我是服务端，能帮助你吗？");            }        });        server.start();        Thread.sleep(Integer.MAX_VALUE);        server.stop();    }    /**     *  给所有连接客户端推送消息     * @param eventType 推送的事件类型     * @param message  推送的内容     */    public void sendMessageToAllClient(String eventType,String message){        Collection<SocketIOClient> clients = server.getAllClients();        for(SocketIOClient client: clients){            client.sendEvent(eventType,message);        }    }    /**     * 停止服务     */    public void stopServer(){        if(server != null){            server.stop();            server = null;        }    }    public static SocketIOServer getServer() {        return server;    }}

客户端启动服务

var socketUrl = "<%=path%>/startServer.do";        $.ajax({            url:socketUrl,            type:'get',            success:function(){            }        })

//启动socket 服务    @RequestMapping(value = "startServer.do")    public void startServer(HttpServletResponse response) {        response.setHeader("Access-Control-Allow-Credentials", "true");        response.setHeader("Access-Control-Allow-Origin", "*");        try {            if (serviceIo.getServer() == null) {                new Thread(new Runnable() {                    @Override                    public void run() {                        try {                            serviceIo.startServer();                        } catch (InterruptedException e) {                            logger.error(e);                        }                    }                }).start();            }        } catch (Exception e) {            logger.error(e);        }    }

服务端推送数据

serviceIo.sendMessageToAllClient("advert_data", JSonFactory.bean2json(data));

客户端接收推送数据，socket.io.js在git上可下载

<script type="text/javascript" src="<%=basePath%>/resources/js/socketio/socket.io.js"></script>var socket = io.connect('http://192.168.31.141:9092');socket.on('advert_data',function(data){    var personInfo = JSON.parse(data);    console.log(personInfo);});
