openshift + spring websocket

Question

我是openshift的新手，目前嘗試在那裏設置我的websocket應用程序，但有一些問題。當我試圖連接到

WS：//app-domain.rhcloud.com：8000 /路徑

我得到以下異常：

Caused by: java.lang.IllegalArgumentException: No 'javax.websocket.server.Server Container' ServletContext attribute. Are you running in a Servlet container that 
supports JSR-356? 
    at org.springframework.util.Assert.notNull(Assert.java:112) 
    at org.springframework.web.socket.server.standard.AbstractStandardUpgradeStrategy.getContainer(AbstractStandardUpgradeStrategy.java:68)

    at org.springframework.web.socket.server.support.WebSocketHttpRequestHandler.handleRequest(WebSocketHttpRequestHandler.java:127) 
    ... 25 more 

當我運行的應用程序當地一切正常與下列網址：

WS：//本地主機：8090 /路徑

對於這兩種情況下，我使用Tomcat 7 Spring配置：

<websocket:handlers allowed-origins="*"> 
    <websocket:mapping path="/fight-core" handler="webSocketHandler"/> 
    <websocket:handshake-interceptors> 
     <ref bean="webSocketHandshakeInterceptor"/> 
    </websocket:handshake-interceptors> 
</websocket:handlers> 

而且我已經在我的pom.xml和W與WebSocket的-API的依賴嘗試/ O它

顯然這不是關於Spring和Tomcat，而是關於Openshift的路由層;它看起來像WebSocket的支持仍處於試驗階段，請參閱： * a blog post from 2012 explaining the situation * Openshift official documentation

對於純WebSocket連接（WS：//），請求定向到端口 8000，而的WebSocket安全連接（WSS：/ /）使用下面的示例示出端口8443，作爲 ：http://example.example.com:8000 https://example.example.com:8443
