HTML5WebSocket点对点谈天实现办法-

本文主要和大家介绍HTML5WebSocket实现点对点谈天的示例代码的相干材料,小编觉得挺不错的，此刻分享给大家，也给大家做个参照 。一起追随小编过来看看吧，但愿能帮忙到大家。 昨天运用HTML5的websocket与Tomcat实现了多人谈天，那是最简略也是最根本的，其中注意的就是开发环境，要知足jdk1.7和tomcat8，固然了tom7 的7.063也行！

本文主要和大家介绍HTML5 WebSocket实现点对点谈天的示例代码的相干材料,小编觉得挺不错的，此刻分享给大家，也给大家做个参照 。一起追随小编过来看看吧，但愿能帮忙到大家。

public class InitServlet extends HttpServlet {
    private static final long serialVersionUID = -3163557381361759907L;  
    private static HashMap socketList;    
    public void init(ServletConfig config) throws ServletException {    
        InitServlet.socketList = new HashMap();    
        super.init(config);    
        System.out.println("初始化谈天容器");    
    }    

    public static HashMap getSocketList() {    
        return InitServlet.socketList;    
    }    
}

这里你可以跟本人的系统联合，对应的web配置代码如下：

    
        websocket
        socket.MyWebSocketServlet
    
    
        websocket
        *.do
    

    
        initServlet
        socket.InitServlet
        1
    
    
        index.jsp
    

这就是最普通的前台像后台发送要求的历程，也是很容易嵌入到本人的系统里

MyWebSocketServlet：

public class MyWebSocketServlet extends WebSocketServlet {
    public String getUser(HttpServletRequest request){
        String userName = (String) request.getSession().getAttribute("user");
        if(userName==null){
            return null;
        }
        return userName;  
    }  
    protected StreamInbound createWebSocketInbound(String arg0,
            HttpServletRequest request) {
        System.out.println("会员" + request.getSession().getAttribute("user") + "登录");
        return new MyMessageInbound(this.getUser(request)); 
    }
}

MyMessageInbound继承MessageInbound

package socket;
import java.io.IOException;
import java.nio.ByteBuffer;
import java.nio.CharBuffer;
import java.util.HashMap;
import org.apache.catalina.websocket.MessageInbound;
import org.apache.catalina.websocket.WsOutbound;
import util.MessageUtil;
public class MyMessageInbound extends MessageInbound {
    private String name;
    public MyMessageInbound() {
        super();
    }

    public MyMessageInbound(String name) {
        super();
        this.name = name;
    }

    @Override  
    protected void onBinaryMessage(ByteBuffer arg0) throws IOException {  

    }  

    @Override  
    protected void onTextMessage(CharBuffer msg) throws IOException { 
        //会员所发新闻处置后的map
        HashMap messageMap = MessageUtil.getMessage(msg);    //处置新闻类
        //上线会员汇合类map
        HashMap userMsgMap = InitServlet.getSocketList();
        String fromName = messageMap.get("fromName");    //新闻来自人 的userId
        String toName = messageMap.get("toName");         //新闻发往人的 userId
        //猎取该会员
        MessageInbound messageInbound = userMsgMap.get(toName);    //在仓库中掏出发往人的MessageInbound
        MessageInbound messageFromInbound = userMsgMap.get(fromName);
        if(messageInbound!=null && messageFromInbound!=null){     //要是发往人 存在进行操纵
            WsOutbound outbound = messageInbound.getWsOutbound(); 
            WsOutbound outFromBound = messageFromInbound.getWsOutbound();
            String content = messageMap.get("content");  //猎取新闻内容
            String msgContentString = fromName + "说: " + content;   //结构发送的新闻
            //发出去内容
            CharBuffer toMsg =  CharBuffer.wrap(msgContentString.toCharArray());
            CharBuffer fromMsg =  CharBuffer.wrap(msgContentString.toCharArray());
            outFromBound.writeTextMessage(fromMsg);
            outbound.writeTextMessage(toMsg);  //
            outFromBound.flush();
            outbound.flush();
        }
    }  

    @Override  
    protected void onClose(int status) {  
        InitServlet.getSocketList().remove(this);  
        super.onClose(status);  
    }  

    @Override
    protected void onOpen(WsOutbound outbound) {  
        super.onOpen(outbound);  
        //登录的会员注册进去
        if(name!=null){
            InitServlet.getSocketList().put(name, this);//寄存客服ID与会员
        }
    }

    @Override
    public int getReadTimeout() {
        return 0;
    }  
}

在onTextMessage中处置前台发出的信息，并封装信息传给指标

还有一个messageutil

package util;
import java.nio.CharBuffer;
import java.util.HashMap;
public class MessageUtil {
    public static HashMap getMessage(CharBuffer msg) {
        HashMap map = new HashMap();
        String msgString  = msg.toString();
        String m[] = msgString.split(",");
        map.put("fromName", m[0]);
        map.put("toName", m[1]);
        map.put("content", m[2]);
        return map;
    }
}

固然了，前台也要按照规定的格局传信息

    pageEncoding="UTF-8"%>
