DispatchAction 을 이용해서 인증하기

DispatchAction을 이용해서 회원접근을 관리하는 방법이다. 

급조한 거라 이런식으로 하면된다는 것이고 나머지는 응용해서 하면된다. 

GuestLoginAction 클래스로 만들고 GuestAction 에서 

이를 상속받으면 간단하게 해결된다.

public class GuestLoginAction extends DispatchAction{ 

   public ActionForward execute(ActionMapping mapping, 
           ActionForm form, 
           HttpServletRequest request, 
           HttpServletResponse response) 
    throws Exception{ 

       HttpSession session = request.getSession(); 

       String user = (String)session.getAttribute("user"); 

       if(user == null){ 

           return new ActionForward("/jsp/login.jsp", true); 

       }else{ 

        return dispatchMethod(mapping, 
               form, 
               request,
