Spring MVC: got “ambiguous mapping found” error when extending annotated base controller with @Controller

问题

I am using Spring MVC 3.2.4. I want to extend an existing annotated base controller to override some existing methods. Here is what I want to do,

/**Base Controller**/
 @controller
 public class BaseController {

  @RequestMapping(value="/process")
  public String doStuff(){
   //do something
  }
 }

/**Child Controller**/
@controller
public class ChildController extends BaseController {

  @RequestMapping(value="/specicalProcess")
  public String doStuff(){
  //do special thing
  super.doStuff();
 }
}

But I got "ambiguous mapping found" error. I wonder if Spring MVC doesn't support overriding a super method with @RequestMapping annotation and how I can extend annotated base controller. In my case, I don't want to remove all annotation from base controller to make it work. Any thoughts? Many thanks in advance.
