标签: spring tomcat sockjs

我使用tomcat 7.0.77,spring,现在sockjs无法打开信息。 的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>

的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();

catalina.out中 信息:映射的URL路径[/ sockjs / webSocketServer / **]到[class org.springframework.web.socket.sockjs.support.SockJsHttpRequestHandler]类型的处理程序 2017年7月17日下午1:01:46 org.springframework.web.servlet.handler.SimpleUrlHandlerMapping registerHandler

HTML

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

当我将/ 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

感谢

将servlet-mapping / sockjs / *添加到web.xml 并将html更改为 websocket = new SockJS(&#34; http://&#34; + local +&#34; / sockjs / sockjsWebSocketServer&#34;);

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