websocket的EndPoint如何访问HttpSession

[想喝咖啡的貓]

RT，发现jsr356新规范中Endpoint的Session跟本就是一个独立的东西，如何在web项目中使用HttpSession?

package org.sl.action;

import org.apache.log4j.Logger;

import javax.websocket.*;
import javax.websocket.server.ServerEndpoint;

/**

@ServerEndpoint(value="/echoendpoint")
public class EchoEndpoint {
    static final Logger logger = Logger.getLogger(EchoEndpoint.class);

    @OnOpen
    public void start(Session session){
        System.out.println("session "+session.getId()+" open.");
    }

    @OnMessage
    public void process(Session session, String message){
        System.out.println("rece:" + message);
        RemoteEndpoint.Basic remote = session.getBasicRemote();
        int c = Integer.valueOf(message);

        try {
            for (int i=1; i<=c; i++){
                remote.sendText("response "+i);
                Thread.sleep(500);
            }
        } catch (Exception e) {
            logger.error(e.getMessage(), e);
        }
    }

    @OnClose
    public void end(Session session){
        System.out.println("session "+session.getId()+" close.");
    }

    @OnError
    public void error(Session session, java.lang.Throwable throwable){
        System.err.println("session "+session.getId()+" error:"+throwable);
    }
}
