sockjs信息404错误

Question

我用的是tomcat 7.0.77，spring，现在sockjs不能打开信息。web.xml

       <servlet>
                <servlet-name>mvc-dispatcher</servlet-name>
                <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                <load-on-startup>1</load-on-startup>
                <async-supported>true</async-supported>
        </servlet>

        <servlet-mapping>
                <servlet-name>mvc-dispatcher</servlet-name>
                <url-pattern>/cmd/*</url-pattern>
                <url-pattern>/webSocketServer</url-pattern>
                <url-pattern>/sockjs/webSocketServer/*</url-pattern>
                <url-pattern>/sockjs/webSocketServer/info</url-pattern>
                <url-pattern>/webSocketServerLogout</url-pattern>
                <url-pattern>/webSocketServerSpAlarm</url-pattern>

java

public class WebSocketConfig extends WebMvcConfigurerAdapter implements WebSocketConfigurer {
    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
//        registry.addHandler(systemWebSocketHandler(),"/webSocketServer").addInterceptors(new WebSocketHandshakeInterceptor());

        registry.addHandler(systemWebSocketHandler(), "/sockjsWebSocketServer").addInterceptors(new WebSocketHandshakeInterceptor())
.withSockJS();

服务器信息:已将URL path /sockjs/webSocketServer/**映射到org.springframework.web.socket.sockjs.support.SockJsHttpRequestHandler类处理程序2017年7月17日下午1:01:46 PM org.springframework.web.servlet.handler.SimpleUrlHandlerMapping catalina.out

html

websocket = new SockJS("http://"+local+"/sockjs/webSocketServer");

当我像上面那样将/sockjs/webSocketServer/info添加到web.xml中时，首先无法打开/sockjs/webSocketServer/info，报告http://172.24.170.178/sockjs/webSocketServer/093/vl3vnd0p/websocket 404错误

谢谢

将servlet-mapping /sockjs/*添加到web.xml，并将html更改为websocket = new SockJS("http://"+local+"/sockjs/sockjsWebSocketServer")；

好了。因为对于sockjs，在webConfig中的java map url不能直接把它放到web.xml中。需要添加前缀sockjs(示例)。
