Java 添加拦截器时发生异常

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

只有当我添加了拦截器时，才会发生这种情况：

@Component
public class ExternalLinkInterceptor extends HandlerInterceptorAdapter {

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

我不明白这个异常意味着什么，我需要帮助。

您可能有这个

xmlns:mvc=”http://www.springframework.org/schema/web-services“

出于其他原因。您需要将其更改为：

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

带schemaLocation（针对上述内容）

---

使用web服务命名空间，您使用的是Spring WS

标记，该标记期望

org.springframework.WS.server.EndpointInterceptor

实例，而不是

org.springframework.web.servlet.HandlerInterceptor

，您使用的是

MessageDispatcherServlet

？@SotiriosDelimanolis我不知道，所以我会回答，没有。你能检查一下你的

web.xml

吗。您正在使用哪个servlet？我认为对于SpringWS，您需要使用

EndpointInterceptor

而不是

HandlerInterceptorAdapter

。DispatcherServlet是我使用的唯一一个servlet

appServlet org.springframework.web.servlet.DispatcherServlet contextConfigLocation web-INF/Spring/servlet-context.xml1

试试我在下面发布的内容。我认为这是一个xml名称空间问题。我认为你是对的，我交换了这两个名称空间，不幸的是，我遇到了另一个例外，但这远远不是这个问题：-）谢谢
