無法運行彈簧web套接字演示

Question

我試圖運行彈簧web套接字的演示，但無法完全測試它。我使用的是Java 7和Tomcat 7.0.50。我在服務器啓動時沒有收到任何錯誤，但是當我用js打開連接到它的網頁時，我找不到404頁面。我不確定我是否缺少配置中的任何內容以使其運行，並且如何能夠從js端連接它。

我有以下XML文件：

<beans ....> 
    <context:annotation-config /> 

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

我的控制器類是：

@Controller 
public class SwsService { 
    @MessageMapping("/hello") 
    @SendTo("/topic/greetings") 
    public Greeting greeting(HelloMessage message) throws Exception { 
     return new Greeting("Hello, " + message.getName() + "!"); 
    } 

    public String getGreeting() { 
     return "Hello, you are in!"; 
    } 
} 

的JS從中我打電話是這樣的：

var sock = new SockJS("/hello"); 
sock.onopen = function() { 
    console.log("open"); 
}; 
sock.onclose = function() { 
    console.log("closed"); 
}; 
sock.onmessage = function (message) { 
    console.log("msg", message); 
}; 

控制檯輸出時我運行tomcat：

瀏覽器控制檯輸出：

GET http://localhost:8080/hello/info 404 (Not Found) sockjs-0.3.min.js:27 
closed 

我怎樣才能成功地測試了嗎？

更新

我還試圖從這裏運行的組合例如：https://github.com/rstoyanchev/spring-websocket-portfolio通過@jhadesdev

的建議，但也於事無補。當我運行mvn tomcat7:run，我看到瀏覽器下面的輸出，並打開URL告訴404

它卡在那裏，並沒有繼續。

Answer 1

This Chrome擴展可以幫助您測試Websockets。你

也可以看看使用Spring Boot使用WebSockets我simple-chat項目。

Answer 2

嘗試在webapp中添加資產文件夾，其中所有stomp和sockjs.js文件都可用。看一下running application的這個例子，可以用mvn clean install jetty:run運行。

的問題似乎是，要麼sockjs不在服務器上或一些道路是錯誤的。基於鏈路上的例子，一跺腳端點可以configured like this：

@EnableWebSocketMessageBroker 
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { 
    @Override 
    public void registerStompEndpoints(StompEndpointRegistry registry) { 
     registry.addEndpoint("/portfolio").withSockJS(); 
    } 

} 

然後在JavaScript中的終點可以這樣調用：

var socket = new SockJS('/spring-websocket-portfolio/portfolio') 
var stompClient = Stomp.over(socket); 

其中/spring-websocket-portfolio是根部署路徑的應用。

Answer 3

你的應用程序看起來不錯。

你絕對應該前綴你的應用程序的根上下文JavaScript的請求，爲jhadesdev mentioned。

您的應用程序是否註冊其他過濾器或自定義messageconverters？也許某些其他配置元素在此干擾。

最新的投資組合例子應該肯定的工作，這裏有一些問題：

1. 你能告訴我們更多關於您的客戶端安裝程序（瀏覽器版本）？
2. 您的瀏覽器是否支持websocket（測試它there）？
3. 你還可以嘗試在隱身模式下（也許第三方瀏覽器擴展出現故障）？
4. 您可以檢查您的瀏覽器是否使用本地主機請求的HTTP代理？
5. 你能檢查這個HTTP 404是否在Tomcat訪問日誌中？ （並看看你是否有這些或在catalina.out有趣的東西？）

Answer 4

我正面臨同樣的問題。這個線程給了我足夠的線索來解決這個問題。非常感謝。

SOLUTION： 如果你有一個Spring MVC調度的Servlet在web.xml配置並映射到URL模式如下圖所示

<servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/webui/*</url-pattern> 
</servlet-mapping> 

然後，你必須創建SockJS實例作爲下面

var socket = new SockJS('/contextPath/webui/hello'); 

注示：替換的contextPath其中y我們的應用上下文路徑

Answer 5

您的DispatcherServlet如何映射？ Here可能是你要找的東西
