您好我有以下异常：

ERROR 13 May 2013 15:20:17,471 http-9090-1 org.springframework.web.servlet.DispatcherServlet - Context initialization failed

这只在我添加拦截器时发生了：

@Component
public class ExternalLinkInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
            throws Exception {
//code
}

编辑 更新： 的applicationContext.xml：

我不明白这个例外意味着什么，我需要帮助。

答案 0 :(得分：2)

由于某些其他原因，您可能会拥有此xmlns:mvc="http://www.springframework.org/schema/web-services"。您需要将其更改为：

xmlns:mvc="http://www.springframework.org/schema/mvc"

with schemaLocation（对于上面的内容）

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"

使用Web服务命名空间，您使用的是Spring WS <interceptors>标记，该标记期望org.springframework.ws.server.EndpointInterceptor个实例而不是org.springframework.web.servlet.HandlerInterceptor。
