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

import com.aptech.dao.UserDAO;

public class UpdateServlet extends HttpServlet {

	
	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
		String uname = request.getParameter("uname");
		String oldPassword = request.getParameter("oldPassword");
		String newPassword = request.getParameter("newPassword");
		String newPassword2 = request.getParameter("newPassword2");
		
		if(newPassword.equals(newPassword2) == false){
			request.setAttribute("tip", "两次密码输入不一致");
			request.setAttribute("r", "updatepassword.jsp");
			request.getRequestDispatcher("tip.jsp").forward(request, response);
			return;
		}
		
		UserDAO ud = new UserDAO();
		boolean b = ud.update(uname, oldPassword, newPassword);
		if(b){
			request.setAttribute("tip", "恭喜，密码修改成功");
		}else{
			request.setAttribute("tip", "对不起，密码修改失败，<br>可能原因：1.旧密码不正确；2.发生未知错误！");
