一个非常简单的mvc留言板MVC框架是STRUTS框架的基础

package com.aptech.servlet;

import java.io.IOException;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.aptech.dao.SayingDAO;

public class SayinglistServlet extends HttpServlet {

	
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		String curpage = request.getParameter("curpage");
		curpage = (curpage == null ? "1" : curpage);
		String pagesize = request.getParameter("pagesize");
		pagesize = (pagesize == null ? "5" : pagesize);
		
		SayingDAO ds = new SayingDAO();
		List list = ds.getSayingsByPage(Integer.parseInt(curpage), 
				Integer.parseInt(pagesize));
		request.setAttribute("list", list);
		request.setAttribute("curpage", curpage);
		request.setAttribute("pagesize", pagesize);
		request.setAttribute("maxpage", 
				ds.getPageCount(Integer.parseInt(pagesize)));
		request.setAttribute("totalItems", ds.getSize());
		
		request.getRequestDispatcher("sayinglist.jsp").forward(request, response);
