Websocket停止在tomcat 7.0.50上工作

Question

 Windows Host file : I use dummy host name through Windows host file:
127.0.0.1    phasingapp.com
127.0.0.1    pricer.com

old  :  ws://localhost:86/websocket/filuploadtrackerendpoint
new : ws://phasingapp.com:86/websocket/filuploadtrackerendpoint

 <Location /jkweb/websocket/>
    Require host phasingapp.com granted
</Location>

 changed url pattern for Struts 2 filter from ".action to " /* ". Also added exclusion   filters
 to strtus2  for webscoket urls :

<constant name="struts.action.excludePattern" value=".*websocket/.*"/>

下面是我的ServerEndPoint类：

      package com.jkweb.websocket;

        import java.io.IOException;
        import java.util.HashMap;
        import java.util.List;
        import java.util.Map;

        import javax.websocket.EndpointConfig;
        import javax.websocket.OnMessage;
        import javax.websocket.OnOpen;
        import javax.websocket.Session;
        import javax.websocket.server.PathParam;
        import javax.websocket.server.ServerEndpoint;

        import org.slf4j.Logger;
        import org.slf4j.LoggerFactory;

        @ServerEndpoint(value="/websocket/fileuploadtracker")
       public class FileUploadTrackerEndPoint{
       private static final Logger logger = LoggerFactory
            .getLogger(FileUploadTrackerEndPoint.class);
       private static HashMap<String,Session> socketConnectionMap = new    HashMap<String,Session>();

    @OnOpen 
    public void open(Session session) {
        Map<String,List<String>> paramMap = session.getRequestParameterMap();
        List<String> uniqueTockenValues = paramMap.get("uniqueTocken");
        if(uniqueTockenValues != null && uniqueTockenValues.size() > 0){
            socketConnectionMap.put(uniqueTockenValues.get(0),session); 
        }
    }
    @OnMessage
    public void onMessage(Session session, String msg) {
        try {
            session.getBasicRemote().sendText(msg);
        } catch (IOException e) {
            logger.error(e.getMessage());
        }
    }

    public static void sendMessage(String uniqueTocken,String msg){
        try {
            Session wsSession = socketConnectionMap.get(uniqueTocken);
            wsSession.getBasicRemote().sendText(msg);
        } catch (IOException e) {
            logger.error(e.getMessage());
        }
    }
}

和我的javascript代码：

createFileUploadWebSocket : function(){
            var that = this;
            var uniqueTocken = $("#uniqueTocken").val(),
            wsurl =  "ws://phasingapp.com:86/jkweb/websocket/fileuploadtracker?uniqueTocken="+uniqueTocken,
            ws;
            ws = new WebSocket(wsurl);
             ws.onopen = function()
             {
                 alert("opened..") //I get this aler sothis is called
                 ws.send("test");//however this has not effect ...no error but server end point is not called
             };
             ws.onmessage = function (evt) 
             { 
                 message = evt.data;
                 if(message == "Done."){
                     alert("closing..");
                     ws.close();
                     $('#progressbar').progressbar('option','value',100);
             }
                 var currentVal = $('#progressbar').progressbar('option','value');
                 $('#progressbar').progressbar('option','value',currentVal <= 80 ?currentVal+1 : currentVal);
             };
             ws.onclose = function(evt)
             { 
                // websocket is closed.
                alert("Connection is closed..."+evt.code + ":"+evt.reason ); 
             };

             ws.onerror = function(evt){
                 alert("Connection is closed..."+evt.code + ":"+evt.reason );
             };

        },

同样，对于所有其他websocket问题，我在配置错误本身找到了答案。

 ProxyPass /jkweb  !
 ProxyPass /jkweb/  !
 ProxyPass /jkweb/websocket/  ws://localhost:8080/jkweb/websocket/
 ProxyPassReverse /jkweb/websocket/  ws://localhost:8080/jkweb/websocket/
 ProxyPass /  http://localhost:8080/jkweb/
 ProxyPassReverse /  http://localhost:8080/jkweb/

我更改了proxypass指令的顺序，如下所示：

 ProxyPass /jkweb/websocket/  ws://localhost:8080/jkweb/websocket/
 ProxyPassReverse /jkweb/websocket/  ws://localhost:8080/jkweb/websocket/
 ProxyPass /jkweb  !
 ProxyPass /jkweb/  !
 ProxyPass /  http://localhost:8080/jkweb/
 ProxyPassReverse /  http://localhost:8080/jkweb/

在websocket的proxypass指令导致以jkweb/开头的每个请求绕过代理之前放置它。
