package per.zww.web;

import javax.servlet.http.HttpSession;
import javax.websocket.HandshakeResponse;
import javax.websocket.server.HandshakeRequest;
import javax.websocket.server.ServerEndpointConfig;
import javax.websocket.server.ServerEndpointConfig.Configurator;
/*
 * 获取HttpSession
 * 
 */

public class GetHttpSessionConfigurator extends Configurator {

    @Override
    public void modifyHandshake(ServerEndpointConfig sec,
            HandshakeRequest request, HandshakeResponse response) {
        // TODO Auto-generated method stub
        HttpSession httpSession=(HttpSession) request.getHttpSession();
        sec.getUserProperties().put(HttpSession.class.getName(),httpSession);
    }
    
}

第一步：新建一个GetHttpSessionConfigurator类并继承Configurator类

@ServerEndpoint(value="/socketTest",configurator=GetHttpSessionConfigurator.class)

第二步：然后在@ServerEndpoint注解里面添加configurator属性

@OnOpen
    public void onOpen(Session session,EndpointConfig config) {
        HttpSession httpSession= (HttpSession) config.getUserProperties().get(HttpSession.class.getName());
        System.out.println( httpSession.getAttribute("name"));
        sessionMap.put(session.getId(), session);
    }

第三步：在onOpen方法里加入参数EndpointConfig config即可获取HttpSession
