带websockets的弹簧PATCH

当我们在Tomcat 7.0.56上部署我们的站点时，我在使用websockets的弹簧应用程序时出错。我尝试访问的WebSocket端点路径是application/wsconnection/ws它显示nosuchfielderror：PATCH带websockets的弹簧PATCH

exception 

javax.servlet.ServletException: Servlet execution threw an exception 
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) 
    org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter.doFilter(StrutsPrepareAndExecuteFilter.java:96) 
    org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:88) 
    org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76) 
root cause 

java.lang.NoSuchFieldError: PATCH 
    org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:833)

    org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:88) 
    org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:76)

，但是当我尝试在本地运行它

Can "Upgrade" only to "WebSocket".

确实错误发生的原因与Tomcat的罐子冲突？我检查了tomcat.websocket和其他人的har的源文件，但没有PATCH字段。 websocket与服务器端点握手时发送了什么？

servlet的路径是/wsconnection/*，端点路径是'/ ws`。

servlet的context.xml中/调度程序-servlet.xml中

它仅包含包括其他XML上下文。

能否请你分享一下pom.xml – 2014-11-25 10:04:21

我不认为这是一个tomcat问题。这种例外表明版本不匹配。确保您在所有弹簧依赖关系中使用相同的版本。

与你分享你的pom.xml，web.xml和servlet上下文也会有所帮助。
