在本项目中再添加实现用户注册的功能

1、添加userRegister.jsp

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

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 here

}

public 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 here

}

 

}

3、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;

}

else

{

okOrNot=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();

try

{

java.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;

    select_SqlStatement="select * from userInfo where userName='"+

                               userName+"' and userPassWord='"+userPassWord+"'";

con=connectDBBean.getConnection();

try

{

java.sql.PreparedStatement pstmt = con.prepareStatement(select_SqlStatement,

ResultSet.TYPE_SCROLL_SENSITIVE,

ResultSet.CONCUR_UPDATABLE);

rs = pstmt.executeQuery();

if(rs.next())

{

oneUserInfo=new UserInfoPO();   //目前只转换下面的几个属性

oneUserInfo.setUserName(rs.getString("userName"));

oneUserInfo.setUserPassWord(rs.getString("userPassWord"));

oneUserInfo.setUserDepartment(rs.getString("userDepartment"));

}

else

{

oneUserInfo=null;

}

}

catch(SQLException e)

{

System.out.println("在查询数据库表时出现错误!");

}

return oneUserInfo;

}

public ArrayList SelectSomeUserInfoData(Map whereMap) {

// TODO 自动生成方法存根

return null;

}

public boolean UpdateOneUserInfo(UserInfoPO oneUserInfoPO) {

// TODO 自动生成方法存根

return false;

}

}

5、部署并执行本系统
