package com.org.struts;

import javax.servlet.http.*;
import org.apache.struts.action.RequestProcessor;

public class CustomRequestProcessor extends RequestProcessor {

    protected boolean processPreprocess(HttpServletRequest request,
            HttpServletResponse response) {

        boolean continueProcessing = true;

        HttpSession session = request.getSession();
        String uri =request.getRequestURI();
        if ( session == null || session.getAttribute("username") == null ) {
            continueProcessing = false;  

        if(uri.endsWith("login.do")) return true;    
        try{
            response.sendRedirect("/news/" );//有待改进。
          }catch( Exception ex ){
            log.error( "Problem sending redirect from processPreprocess()" );
          }
        }
        return continueProcessing;
    }
