Java 弹簧4.2.4 WebSocket/Stomp和Tomcat失败诱饵

在tomcat上运行的spring（4.2.4）的帮助下，我一直在努力构建一个示例web应用程序，该应用程序使用stomp over websocket/sockjs。开发环境基于eclipse luna和嵌入式maven。在任何情况下，请遵循此处列出的spring指南： 最初，我使用的配置是dispatcher servlet.xml中的完整message broker（不是简单的内存代理）：

    <websocket:message-broker application-destination-prefix="/app">
       <websocket:stomp-endpoint path="/stomp">
          <websocket:sockjs/>
       </websocket:stomp-endpoint>
       <websocket:stomp-broker-relay prefix="/topic,/queue"
           relay-host="localhost" relay-port="61613"
           heartbeat-send-interval="20000" heartbeat-receive-interval="21000"
           client-login="my-client" client-passcode="aesdf"
           system-login="syslogin" system-passcode="qwrt"/>
       <websocket:client-inbound-channel>
            <websocket:executor core-pool-size="30" max-pool-size="60" keep-alive-seconds="300"/>
       </websocket:client-inbound-channel>
       <websocket:client-outbound-channel>
            <websocket:executor core-pool-size="31" max-pool-size="61" keep-alive-seconds="301"/>
       </websocket:client-outbound-channel>
       <websocket:broker-channel>
            <websocket:executor core-pool-size="32" max-pool-size="62" keep-alive-seconds="302"/>
        </websocket:broker-channel> 
</websocket:message-broker>  

并从上面的跟踪中截取一些以节省空间…

基本上，这次它无法创建beanorg.springframework.web.socket.server.support.WebSocketHandlerMapping#0'，因为类：javax/websocket/WebSocketContainer未找到，所以初始化错误。但是，该类位于项目的类路径中，因为我可以看到它正在被包含使用tomcat的库。我知道这有很多问题要问，但有人能解释一下spring、tomcat和websockets的情况吗？因为这个问题我似乎无法解决，所以我工作真的很晚了。
对于完整性，我还包括项目的pom：

您似乎缺少jar文件作为依赖项。选择使用Spring4.x版本时，始终建议使用相应版本的BOM表。请在您的POM文件中使用springframework 4.2.4发行版物料清单，这样您就不会错过应用程序类路径中的任何依赖jar文件。感谢您的回复，但我不确定这是否是问题所在……如果您查看随附的POM，javaee api中有一个注释掉的部分，如果未注释，并且范围更改为compile（而不是提供），则列出的异常将消失，但随后会抛出一个新异常，该异常抱怨spring Dispatcher servlet无法转换为javax.servlet。另外，正如我前面提到的，javax.websocket.WebSocketContainer包含在Eclipse中的Tomcats依赖项中，因为我可以看到它。我不明白问题是什么。
