解决 WebSocketHandlerMapping#0': Cannot resolve reference to bean 'org.springframework.web.socket.se

在使用springmvc的websocket配置时 tomcat启动报错

spring xml配置

<websocket:handlers allowed-origins="*">
        <websocket:mapping path="/websocket" handler="systemWebSocketHandler"/>
        <websocket:handshake-interceptors>
            <ref bean="webSocketHandshakeInterceptor"/>
        </websocket:handshake-interceptors>
    </websocket:handlers>  

启动项目时报错如下：

原因是我使用的tomcat版本是tomcat-7.0.42 tomcat版本太老

升级到tomcat-7.0.77后 项目启动成功

I lost a lot of time digging out for the solution, what i found was that spring websocket will only run over Tomcat 7.0.47+, Jetty 9.1+, GlassFish 4.1+, WebLogic 12.1.3+, and Undertow 1.0+ (and WildFly 8.0+) according to spring's documentation shown here

http://docs.spring.io/spring/docs/current/spring-framework-reference/html/websocket.html, so try updating your app server

spring 官方说要使用Tomcat 7.0.47+以上的版本才支持websocket
