使用sockjs使用Spring 4 WebSocket无法连接套接字 [英] Stomp over socket using sockjs can't connect with Spring 4 WebSocket

问题描述

尝试使用sockjs在套接字上使用带有STOMP的Spring 4 WebSocket。
我遇到了问题。

Trying to use Spring 4 WebSocket with STOMP over socket using sockjs. And i faced a problem.

我的配置：

websocket.xml - 春天的一部分上下文

websocket.xml - part of spring context

<websocket:message-broker application-destination-prefix="/app">  
    <websocket:stomp-endpoint path="/ws">                         
        <websocket:sockjs/>                                       
    </websocket:stomp-endpoint>                                   
    <websocket:simple-broker prefix="/topic"/>                    
</websocket:message-broker>       

控制器代码：

@MessageMapping("/ws")
@SendTo("/topic/ws")
public AjaxResponse hello() throws Exception {
    AjaxResponse ajaxResponse = new AjaxResponse();
    ajaxResponse.setSuccess(true);
    ajaxResponse.addSuccessMessage("WEB SOCKET!!! HELL YEAH!");
    return ajaxResponse;
}

客户端：

var socket = new SockJS("<c:url value='/ws'/>");               
var stompClient = Stomp.over(socket);                             
stompClient.connect({}, function(frame) {                         
    alert('Connected: ' + frame);                                 
    stompClient.send("/app/ws", {}, {});                       
    stompClient.subscribe('/topic/ws', function(response){ 
        alert(response.success);                                  
    });                                                           
});                                                               

输出：

Opening Web Socket... stomp.js:130
GET http://localhost:8080/ws/info 404 (Not Found) sockjs-0.3.js:807
Whoops! Lost connection to undefined stomp.js:130

我做错了什么？

我在google（TickerStocks或类似的东西，问候应用程序（Spring的例子））中找到了一些例子，所有这些都给了我同样的错误。我尝试使用WebSocket握手（没有sockjs） - 相同的结果）。

I've found examples in google (TickerStocks or something like that, greeting applications (example of Spring)) and all of them give me the same error. I trying use WebSocket with handshake (without sockjs) - same result).

附加信息：

方法 public AjaxResponse hello（）; 放在根上下文/的IndexController中。所以我可以提供完整路径： http：// localhost：8080 / ws 。
部署经过测试的tomcat7和tomcat8。

Method public AjaxResponse hello(); placed in IndexController on root context "/". So i can provide full path: http://localhost:8080/ws. To deploy tested tomcat7 and tomcat8.

推荐答案

我按照 Boris The Spider 建议我开始使用Java配置（AppConfig和WebInit文件）而不是XML配置文件。当我完成迁移 - 我尝试了websockets - 它是有效的！我认为主要的问题是WebSocket的XML配置。

I follow Boris The Spider advice and i started use Java Configuration (AppConfig and WebInit files) instead of XML configuration files. When i finished migration - i tried websockets - and it is works! I thought that the main problem was in XML configuration for WebSocket.
