異常增加攔截器

Question

當

你好，我有這樣的以下情況例外：

@Component 
public class ExternalLinkInterceptor extends HandlerInterceptorAdapter { 

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

編輯更新： 的applicationContext.xml

當我加入攔截這隻happended：

我不明白這是什麼異常意味着，我需要幫助。

Answer 1

由於某些其他原因，您可能有此xmlns:mvc="http://www.springframework.org/schema/web-services"。你會想將它更改爲：

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

用的schemaLocation（對於以上）

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

與Web服務的命名空間，你使用Spring WS <interceptors>標籤，它預計org.springframework.ws.server.EndpointInterceptor實例，而org.springframework.web.servlet.HandlerInterceptor。
