Websocket在tomcat 7.0.50上停止工作

Question

我最近在tomcat 7.0.50上实现了websocket。我的tomcat运行在apache2.4之后。我使用Strtus 2和Spring Security。它已停止工作。

问题：Websocket连接已成功打开。Javascript事件处理程序成功获取激发。Apache日志显示，该请求被接受为协议升级请求，代码为101Tomcat访问日志还显示了用于协议升级的相同代码101

但是，在服务器端，onOpen消息未被激发。我尝试在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从未被调用，就像onOpen从未被调用一样。

以下是我在它停止工作后所做的更改：

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:的URL

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

为apache:添加了虚拟主机配置

<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/

Struts2:

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/.*"/>

一切似乎都很好，因为我在apache、tomcat、spring-security和Struts2日志中没有任何错误。

但是在服务器端没有调用任何处理程序？

早些时候我也遇到过类似的问题，但这是因为我在我的WEB-INF/lib中放了websocket api jar，这阻止了打开websocket连接。现在连接打开了，但之后没有调用任何处理程序，过了一段时间后，连接关闭了，我想这显然是因为超时。

这是我的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 );
};
},

对于所有其他websocket问题，我在配置(错误配置)本身中找到了答案。

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/

将它放在websocket的proxypass指令之前会导致每个以jkweb/开头的请求绕过代理。
