Websocket停止在tomcat上工作7.0.50

Question

我最近在tomcat 7.0.50上实现了websocket。我的tomcat运行在apache 2.4后面。 我使用了Strtus 2和Spring Security。它已停止工作。

问题： Websocket连接已成功打开。 JavaScript事件处理程序成功启动。 Apache日志显示，请求被接受为具有101码的协议升级请求 Tomcat的访问日志也显示出相同的代码101，用于协议升级

然而在服务器端的OnOpen消息不被烧制。 我试图在javascript的事件处理程序中打开连接后立即发送消息。 JavaScript中没有错误，但服务器端endPoint的onmessage永远不会调用，就像onOpen从不调用。

下面是我所做的更改后，它已停止工作：

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

wesocket网址：

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

添加的虚拟主机设置为Apache：

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

JkMount /jkweb/* localtomcat 
JkUnMount /jkweb/project/content/* localtomcat 
JkUnMount /jkweb/angle/content/* localtomcat 
JkUnMount /jkweb/index.jsp localtomcat 
JkUnMount /jkweb/ localtomcat 

ProxyRequests Off 
ProxyPreserveHost On 

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/ 

的Struts 2：

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/.*"/> 

一切似乎工作正常，因为我在Apache，Tomcat，Spring安全和Struts2日志中的任何地方gettting没有错误。

但是在服务器端没有处理程序被调用？

早些时候我遇到了类似的问题，但这是因为我已经将websocket-api jar放入了我的WEB-INF/lib中，这阻止了websocket连接被打开。现在打开连接，但之后没有处理程序被调用，并经过一段时间的连接显然是因为我猜想timout。

这里是我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); 
      }; 

     }, 

Answer 1

与其他所有我的WebSocket的问题，我找到了答案，我conffiguration（配置错误）本身

再次。

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/ 

我改变的ProxyPass指令的顺序如下图所示：

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/ 

对于WebSocket的ProxyPass指令之前把它造成每个请求开始jkweb /是导致它绕过代理。
