基于Web MVC系统架构实现的用户注册.doc

在本项目中再添加实现用户注册的功能1、添加userRegister.jsp base href= My JSP userRegister.jsp starting page !- 用户名 用户密码 确认密码 用户所属的部门 信息中心 开发部 办公室 宣传部 用户的类型 管理员 普通用户 超级版主 版主 论坛专家 超级会员 会员 用户是否具有对部门管理的权限 有 无 用户图像 Chang.gifLiuMing.gifWang.GIFYang.GIFzhang.GIF 2、修改UserInfoServlet以实现对用户注册表单的请求响应package com.px1987.j2eeweb.servlet;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.RequestDispatcher;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.px1987.j2eeweb.model.*;public class UserInfoServlet extends HttpServlet public UserInfoServlet() super();public void destroy() super.destroy(); / Just puts destroy string in log/ Put your code herepublic void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException response.setContentType(text/html;charset=gb2312);PrintWriter out = response.getWriter();out.println();out.println();out.println( A Servlet);out.println( );out.print( This is );out.print(this.getClass();out.println(, 按时广泛特色 );out.println( );out.println();out.flush();out.close();public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException request.setCharacterEncoding(gb2312); /Struts ?String menuID= request.getParameter(menuID);int menuIDDigit=Integer.parseInt(menuID);switch(menuIDDigit)case 1: /用户登录吗goUserLogin(request,response); break;case 2: /用户注册吗goUserRegister(request,response);break; case 3: /用户密码修改吗goUpdateUserPassWord(request,response);break;public void goUpdateUserPassWord(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException public void goUserRegister(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException String userName= request.getParameter(userName);String userPassWord= request.getParameter(userPassWord);String userDepartment= request.getParameter(userDepartment);String userAdminLevel= request.getParameter(userAdminLevel);String departAdminLevel= request.getParameter(departAdminLevel);String userImage= request.getParameter(userImage);UserInfoVO userInfoVOBean=new UserInfoVO();userInfoVOBean.setUserName(userName);userInfoVOBean.setUserPassWord(userPassWord);userInfoVOBean.setUserDepartment(userDepartment);userInfoVOBean.setUserAdminLevel(Integer.parseInt(userAdminLevel);userInfoVOBean.setDepartAdminLevel(Integer.parseInt(departAdminLevel);userInfoVOBean.setUserImage(userImage);UserInfoManage userInfoManageBean=new UserInfoManage();boolean okOrNot=userInfoManageBean.doUserRegister(userInfoVOBean);if(okOrNot) RequestDispatcher oneRequestDispatcher=request.getRequestDispatcher(index.jsp); oneRequestDispatcher.forward(request, response); else RequestDispatcher oneRequestDispatcher=request.getRequestDispatcher(loginFailure.jsp); oneRequestDispatcher.forward(request, response); public void goUserLogin(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException String userName= request.getParameter(userName);/重构/ userName=new String(userName.getBytes(ISO-8859-1),gb2312);String userPassWord= request.getParameter(userPassWord); / UserInfoManage userInfoManageBean=new UserInfoManage();UserInfoVO userInfoVOBean=new UserInfoVO();userInfoVOBean.setUserName(userName); /也可以采用来实现-自己完成吧！userInfoVOBean.setUserPassWord(userPassWord); boolean okOrNot=userInfoManageBean.doUserLogin(userInfoVOBean); request.setAttribute(userNameString, userName); if(okOrNot) / response.sendRedirect(/J2EEWebApp/loginSuccess.jsp);/转发 RequestDispatcher oneRequestDispatcher=request.getRequestDispatcher(loginSuccess.jsp); oneRequestDispatcher.forward(request, response); else RequestDispatcher oneRequestDispatcher=request.getRequestDispatcher(loginFailure.jsp); oneRequestDispatcher.forward(request, response); /* * Initialization of the servlet. * * throws ServletException if an error occure */public void init() throws ServletException / Put your code here3、修改前面的UserInfoManage 业务组件类以实现用户注册功能的处理package com.px1987.j2eeweb.model;import com.px1987.j2eeweb.dao.*;import java.util.*;public class UserInfoManage public UserInfoManage() / TODO 自动生成构造函数存根public boolean doUserLogin(UserInfoVO oneUserInfoVO)String userName=oneUserInfoVO.getUserName();String userPassWord=oneUserInfoVO.getUserPassWord();boolean okOrNot=false;UserManageDAOInterface oneUserManageDAOJDBCImple=new UserManageDAOJDBCImple();UserInfoPO oneUserInfoPO= oneUserManageDAOJDBCImple.SelectOneUserInfoData(userName, userPassWord);if(oneUserInfoPO=null)okOrNot=false;elseokOrNot=true;/boolean okOrNot=userName.equals(admin)&userPassWord.equals(1234);return okOrNot;public boolean doUserRegister(UserInfoVO oneUserInfoVO) UserManageDAOInterface oneUserManageDAOJDBCImple=new UserManageDAOJDBCImple();UserInfoPO oneUserInfoPO=new UserInfoPO();oneUserInfoPO.setUserName(oneUserInfoVO.getUserName();oneUserInfoPO.setUserPassWord(oneUserInfoVO.getUserPassWord();oneUserInfoPO.setUserAdminLevel(oneUserInfoVO.getUserAdminLevel();oneUserInfoPO.setUserDepartment(oneUserInfoVO.getUserDepartment();oneUserInfoPO.setUserImage(oneUserInfoVO.getUserImage();oneUserInfoPO.setDepartAdminLevel(oneUserInfoVO.getDepartAdminLevel();oneUserInfoPO.setRegisterTime(new Date().toLocaleString(); oneUserInfoPO.setId(int) new Date().getTime() );boolean okOrNot=false;okOrNot=oneUserManageDAOJDBCImple.InsertOneUserInfo(oneUserInfoPO);return okOrNot;4、修改前面的UserManageDAOJDBCImple类以完成用户注册功能的数据访问操作package com.px1987.j2eeweb.dao;import java.util.ArrayList;import java.util.Map;import java.sql.*;public class UserManageDAOJDBCImple implements UserManageDAOInterface private java.sql.Connection con=null;ConnectDBInterface connectDBBean=null;public UserManageDAOJDBCImple() connectDBBean=new ConnectDBBean();public boolean BatchDeleteUserInfo(ArrayList deletedUserIDs) / TODO 自动生成方法存根return false;public boolean DeleteOneUserInfo(int deletedUserID) / TODO 自动生成方法存根return false;public boolean InsertOneUserInfo(UserInfoPO oneUserInfoPO) String insert_SqlStatement=null;insert_SqlStatement=insert into userInfo values(?,?,?,?,?,?,?,?);con=connectDBBean.getConnection();tryjava.sql.PreparedStatement pstmt = con.prepareStatement(insert_SqlStatement,ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);pstmt.setString(1, oneUserInfoPO.getUserName();pstmt.setString(2, oneUserInfoPO.getUserPassWord();pstmt.setString(3, oneUserInfoPO.getUserDepartment();pstmt.setInt(4, oneUserInfoPO.getUserAdminLevel();pstmt.setInt(5, oneUserInfoPO.getDepartAdminLevel();pstmt.setString(6, oneUserInfoPO.getUserImage();pstmt.setString(7, oneUserInfoPO.getRegisterTime();pstmt.setInt(8, oneUserInfoPO.getId();pstmt.executeUpdate();catch(SQLException e)System.out.println(在查询数据库表时出现错误！);return false;return true;public ArrayList SelectAllUserInfoData() / TODO 自动生成方法存根return null;public UserInfoPO SelectOneUserInfoData(String userName, String userPassWord) ResultSet rs=null;UserInfoPO oneUserInfo=null;String select_SqlStatement=null;
