【websocet】这样写能握手成功吗？_html/css_WEB-ITnose

我的握手链接是ws = new WebSocket("ws://localhost:8080/websocket/web"); // 本地
xml配置：

WebSocketMessageServletwebsocket.WebSocketMessageServletWebSocketMessageServlet/webindex.jsp

但是我本地tomcat测试了还是不行，
tomcat项目lib文件夹下的jar包全都要删掉吗？

回复讨论(解决方案)

up..........................

木有人会吗？

public class WebSocketMessageServlet extends WebSocketServlet{     protected StreamInbound createWebSocketInbound(String arg0) {               System.out.println("$$$$$$$$");        return new WebSocketMessageInboundPool("1");      }

这样写就能握手，太奇怪了，明明要重载父类抽象方法才是正确的。

我在浏览器上F12看了一下，错误是这样说的

楼主你的xml配置有问题！
