spring 拦截器报错

[wk84190133]

我的spring配置拦截器的配置如下：
<bean id="formDuplicationInterceptor"
class="com.hundsun.pay.portal.web.interceptor.FormDuplicationInterceptor">
</bean>

<mvc:interceptors>
<bean class="com.hundsun.pay.portal.web.interceptor.FormDuplicationInterceptor" />
</mvc:interceptors>


其中formDuplicationInterceptor拦截器preHandle方法如下，
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {

System.out.println(1);
HandlerMethod handlerMethod = (HandlerMethod) handler;
System.out.println(handlerMethod);
return true;
}
但是执行到 HandlerMethod handlerMethod = (HandlerMethod) handler;就报错，错误如下：
java.lang.ClassCastException: com.hundsun.pay.portal.web.action.CommonAction cannot be cast to org.springframework.web.method.HandlerMethod

哪位大神可以帮忙解决下，多谢！

说明不是这么用 HandlerMethod handlerMethod = (HandlerMethod) handler; 再说handlermethod这里实际也没起到作用

com.hundsun.pay.portal.web.action.CommonAction implements HandlerMethod intface.
