后端需要三个类：注册类、握手类、处理类（终端类）

握手类：

import java.net.InetSocketAddress;import java.net.URI;import java.util.Map;import javax.servlet.http.HttpSession;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.http.server.ServerHttpRequest;import org.springframework.http.server.ServerHttpResponse;import org.springframework.http.server.ServletServerHttpRequest;import org.springframework.web.socket.WebSocketHandler;import org.springframework.web.socket.server.HandshakeInterceptor;public class WebSocketHandshakeInterceptor implements HandshakeInterceptor {    private static Logger logger = LoggerFactory            .getLogger(HandshakeInterceptor.class);    @Override    public boolean beforeHandshake(ServerHttpRequest request,            ServerHttpResponse response, WebSocketHandler wsHandler,            Map<String, Object> attributes) throws Exception {        if (request instanceof ServletServerHttpRequest) {//            ServletServerHttpRequest servletRequest = (ServletServerHttpRequest) request;//            HttpSession session = servletRequest.getServletRequest()//                    .getSession(true);            // 保存session中已登录的用户到websocket的上下文环境中。在推送消息的时候，需要根据当前登录用户获取点位权限            final IbmsUser user = IbmsUserHolder.getUser();            attributes.put(IBMSConstant.SESSION_WEBSOCKET_LOGINED_USER, user);            // if (session != null) {            // // 使用userName区分WebSocketHandler，以便定向发送消息            // String userName = (String) session            // .getAttribute(Constants.SESSION_USERNAME);            // if(userName==null){            // userName = "qianshihua";            // }            // attributes.put(Constants.WEBSOCKET_USERNAME, userName);            // }        }        return true;    }    @Override    public void afterHandshake(ServerHttpRequest request,            ServerHttpResponse response, WebSocketHandler wsHandler,            Exception exception) {        URI uri = request.getURI();        InetSocketAddress remoteAddress = request.getRemoteAddress();        String msg = "afterHandshake*******************\r\nuri:" + uri + ";\r\nremoteAddress;" + remoteAddress;        System.err.println(msg);        logger.debug(msg);    }}

websocket注册类，注册类依赖握手类，可以编码实现，也可以直接通过spring配置实现：

import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.EnableWebMvc;import org.springframework.web.socket.WebSocketHandler;import org.springframework.web.socket.config.annotation.EnableWebSocket;import org.springframework.web.socket.config.annotation.WebSocketConfigurer;import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;@Configuration@EnableWebMvc@EnableWebSocketpublic class WebSocketConfig  implements WebSocketConfigurer {    @Override    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {        registry.addHandler(systemWebSocketHandler(),"/point/webSocketServer.do").addInterceptors(new WebSocketHandshakeInterceptor())//        .setAllowedOrigins("http://localhost:8087","http://10.16.38.21:8087","http://localhost:63342")        ;        registry.addHandler(systemWebSocketHandler(), "/point/sockjs/webSocketServer.do").addInterceptors(new WebSocketHandshakeInterceptor())                .withSockJS();        registry.addHandler(indexConfigWebSocketHandler(),"/app/indexConfig/indexConfigWebSocket.do").addInterceptors(new WebSocketHandshakeInterceptor());    }    @Bean    public WebSocketHandler systemWebSocketHandler(){        return new IbmsWebSocketHandler();    }    @Bean    public WebSocketHandler indexConfigWebSocketHandler(){        return new IndexConfigWebSocketHandler();    }}

后端可以注册多个handler，如上图配置。

handler：

import com.alibaba.fastjson.JSON;import com.alibaba.fastjson.JSONObject;import org.apache.commons.lang3.StringUtils;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.web.socket.CloseStatus;import org.springframework.web.socket.WebSocketHandler;import org.springframework.web.socket.WebSocketMessage;import org.springframework.web.socket.WebSocketSession;import java.util.List;/** * 数据订阅处理类 */public class IndexConfigWebSocketHandler implements WebSocketHandler {    private static final Logger logger = LoggerFactory.getLogger(IndexConfigWebSocketHandler.class);

       logger.info("收到统计项订阅:::" + jsontext);        Object objUser = session.getAttributes().get(                IBMSConstant.SESSION_WEBSOCKET_LOGINED_USER);        if (objUser == null) {            // 取不到session中的用户信息            throw new RuntimeException("会话中无用户信息");        }        JSONObject jsonObject = JSONObject.parseObject(jsontext);        Object optType = jsonObject.get("optType");//状态字段        String data = jsonObject.getString("data");//数据字段        //将数据字段解析成SubscribeBO列表        List<SubscribeBO> subscribeBOs = JSON.parseArray(data, SubscribeBO.class);

           }            return;        }        if (optType != null && "hb".equals(optType)) {            //心跳            return;        }        if (optType != null && "pausePush".equals(optType)) {            //暂时关闭推送            ignoreSession = true;        }        for (int i = 0; i < subscribeBOs.size(); i++) {            SubscribeBO item = subscribeBOs.get(i);            String id = item.getSubscribeId();            String type = item.getSubscribeTypeId();            if (StringUtils.isBlank(id) || StringUtils.isBlank(type)) {                continue;            }            /*if(SubscribeType.WEATHER.getCode().equals(type)){                //如果是天气预报,构造唯一的天气订阅                item.setSubscribeData(JOBDATA_KEY_WEATHER);

               }            }            String msg = "关注";            if (ignoreSession == true) {                msg = "取消关注";            }            logger.info("websocket会话：" + session + msg + "了："                    + SubscribeType.getDes(item.getSubscribeTypeId()) + "  " + item.getSubscribeData());

订阅的信息存储在内存中，形式为<session,List<data>>的键值对

存储工具类：

订阅工具类（subscribeBO）：主要就是将接收到的websocket信息转成java对象

import com.alibaba.fastjson.annotation.JSONField;/** * 订阅的对象 */public class SubscribeBO {    @JSONField(name="statisticsId")    private String subscribeId;    @JSONField(name="statisticsTypeId")    private String subscribeTypeId;    @JSONField(name="statisticsData")    private String subscribeData;    @JSONField(name="statisticsValue")    private String subscribeValue;    public SubscribeBO() {    }    public SubscribeBO(String subscribeTypeId, String subscribeData) {        this.subscribeTypeId = subscribeTypeId;        this.subscribeData = subscribeData;    }    public SubscribeBO(String subscribeId, String subscribeTypeId, String subscribeData) {        this.subscribeId = subscribeId;        this.subscribeTypeId = subscribeTypeId;        this.subscribeData = subscribeData;    }    public String getSubscribeId() {        return subscribeId;    }    public void setSubscribeId(String subscribeId) {        this.subscribeId = subscribeId;    }    public String getSubscribeTypeId() {        return subscribeTypeId;    }    public void setSubscribeTypeId(String subscribeTypeId) {        this.subscribeTypeId = subscribeTypeId;    }    public String getSubscribeData() {        return subscribeData;    }    public void setSubscribeData(String subscribeData) {        this.subscribeData = subscribeData;    }    public String getSubscribeValue() {        return subscribeValue;    }    public void setSubscribeValue(String subscribeValue) {        this.subscribeValue = subscribeValue;    }    @Override    public boolean equals(Object o) {        if (this == o) return true;        if (o == null || getClass() != o.getClass()) return false;        SubscribeBO bo = (SubscribeBO) o;        if (!subscribeTypeId.equals(bo.subscribeTypeId)) return false;        return subscribeData != null ? subscribeData.equals(bo.subscribeData) : bo.subscribeData == null;    }    @Override    public int hashCode() {        int result = subscribeTypeId.hashCode();        result = 31 * result + (subscribeData != null ? subscribeData.hashCode() : 0);        return result;    }}

推送代码太多，主要是通过spring+Quartz进行后台运算，运算完毕之后将值按照订阅（DeviceWSSHolder）反查session，发送到客户端
