项目架构如下：

dao包如下：

dao实现包如下:

实体包如下：

servlet服务层如下：

实现分页包如下：

举一个案例实现网页中的用户管理模块：

首先创建用户的实体类

package cn.happy.easybuy.entity;

import java.util.Date;

//存放用户基本信息
public class User {
    private String id;//用户名 
    private String name;//用户真实姓名
    private String password;//密码
    private String sex;//性别
    private String birthday;//出生日期
    private String identityCode;//身份证号
    private String email;//email
    private String mobile;//手机
    private String address;//收货地址
    private String login;//是否登录
    private int status;//类型  1位普通用户  2位管理员
    
    
    
    
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public String getBirthday() {
        return birthday;
    }
    public void setBirthday(String birthday) {
        this.birthday = birthday;
    }
    public String getIdentityCode() {
        return identityCode;
    }
    public void setIdentityCode(String identityCode) {
        this.identityCode = identityCode;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getMobile() {
        return mobile;
    }
    public void setMobile(String mobile) {
        this.mobile = mobile;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public String getLogin() {
        return login;
    }
    public void setLogin(String login) {
        this.login = login;
    }
    public int getStatus() {
        return status;
    }
    public void setStatus(int status) {
        this.status = status;
    }
    
    
    
    
}

其次我们要做的就是为用户定制专有的方法进行操作也就是Dao包（代码如下）

package cn.happy.easybuy.dao;

import java.util.List;

import cn.happy.easybuy.entity.User;

public interface UserDao {
    //查询所有的用户信息
    public List<User> getAllUserInfo() throws Exception;
    //添加用户信息
    public boolean add(User user) throws Exception;
    
    //验证该用户名是否存在
    public boolean useridOrNot(User user) throws Exception;
    //验证是否登录成功
    public boolean isLoginOrNot(User user) throws Exception;
    
    //根据用户名查找对应的用户的所有信息
    public User getUserInfoByUid(String uid) throws Exception;

    
    /**
     * 根据用户名查找用户方法
     * @param userID
     * @return
     * @throws Exception 
     */
    public User selectByName(String userID) throws Exception;
    /**
     * 修改用户方法
     * @return
     * @throws Exception 
     */
    public int modifyUser(User user) throws Exception;
    
    /**
     * 删除用户方法
     * @param userId
     * @return
     * @throws Exception 
     */
    public int removeUser(String userId) throws Exception;
    /**
     * 查询新闻总记录数
     */
    public int getUserCount() throws Exception;
    /**
     * 查询分页内容相关的用户内容
     * 
     */
    public List<User> getUserInfo(int pageIndex,int pageSize)throws Exception;
    
    
    
}

接下来我们要做的就是为方法进行扩充进行实现方法的功能也就是DaoImpl包（代码如下）：

package cn.happy.easybuy.dao.impl;

import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;

import cn.happy.easybuy.dao.BaseDao;
import cn.happy.easybuy.dao.UserDao;
import cn.happy.easybuy.entity.User;

public class UserDaoImpl extends BaseDao implements UserDao {
    //查询所有的用户信息
    @Override
    public List<User> getAllUserInfo() throws Exception {
        String sql="select * from EASYBUY_USER";
        ResultSet rs=executeQuery(sql);
        List<User> list=new ArrayList<User>();
        if(rs!=null){
            while(rs.next()){
                User user=new User(); 
                user.setId(rs.getString("EU_USER_ID"));
                user.setAddress(rs.getString("EU_ADDRESS"));
                user.setBirthday(rs.getString("EU_BIRTHDAY"));
                user.setEmail(rs.getString("EU_EMAIL"));
                user.setIdentityCode(rs.getString("EU_IDENTITY_CODE"));
                user.setLogin(rs.getString("EU_LOGIN"));
                user.setMobile(rs.getString("EU_MOBILE"));
                user.setName(rs.getString("EU_USER_NAME"));
                user.setPassword(rs.getString("EU_PASSWORD"));
                user.setSex(rs.getString("EU_SEX"));
                user.setStatus(rs.getInt("EU_STATUS"));
                list.add(user);
            }
        }
        return list;
    }
    //添加用户信息
    @Override
    public boolean add(User user) throws Exception {
        //EU_USER_ID, EU_USER_NAME, EU_PASSWORD, EU_SEX, EU_BIRTHDAY, EU_IDENTITY_CODE,
         //EU_EMAIL, EU_MOBILE, EU_ADDRESS, EU_STATUS, EU_LOGIN
        String sql="insert into EASYBUY_USER values(?,?,?,?,?,?,?,?,?,?,?)";
        Object[] objs={
                user.getId(),
                user.getName(),
                user.getPassword(),
                user.getSex(),
                user.getBirthday(),
                user.getIdentityCode(),
                user.getEmail(),
                user.getMobile(),
                user.getAddress(),
                user.getStatus(),
                user.getLogin()
        };
        int count=executeUpdate(sql, objs);
        if(count>0){
            return true;
        }
        return false;
    }
    //验证是否登录成功
    @Override
    public boolean isLoginOrNot(User user) throws Exception {
        String sql="select count(1) as mycount from EASYBUY_USER where EU_USER_ID=? and EU_PASSWORD=?";
        Object[] objs={
                user.getId(),
                user.getPassword()
        };
        ResultSet rs=executeQuery(sql, objs);
        int count=0;
        if(rs!=null){
            while(rs.next()){
                count=rs.getInt("mycount");
            }
        }
        if(count>0){
            return true;
        }
        return false;
    }
    //验证是否存在该用户名
    @Override
    public boolean useridOrNot(User user) throws Exception {
        String sql="select count(1) as mycount from EASYBUY_USER where EU_USER_ID=? ";
        Object[] objs={user.getId()};
        ResultSet rs=executeQuery(sql, objs);
        int count=0;
        if(rs!=null){

            delUserInfo(request,response);

              }
              
              
              cpage1.setPageIndex(pageIndex);

        String sex=request.getParameter("sex");
        String birthday=request.getParameter("birthday");
        String mobile=request.getParameter("mobile");
        String address=request.getParameter("address");
        User ur = new User();
        ur.setId(uid);
        ur.setName(name);
        ur.setPassword(passWord);
        ur.setSex(sex);
        ur.setBirthday(birthday);
        ur.setMobile(mobile);
        ur.setAddress(address);
        int count =0;
        try {
            count=user.modifyUser(ur);
            if (count>0) {
                request.getRequestDispatcher("/servlet/UserServlet?oper=list").forward(request, response);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    /**
     * 实现删除用户的方法
     */
    public void delUserInfo(HttpServletRequest request,HttpServletResponse response){
        String uid = request.getParameter("uid");
        int count =0;
        try {
            count=user.removeUser(uid);
            System.out.println(count);
            if (count>0) {
                request.getRequestDispatcher("/servlet/UserServlet?oper=list").forward(request, response);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        
    }
    
}

最后如果需要给用户模块中的信息用于分页显示则需要page层（代码如下）：

package cn.happy.easybuy.until;

import java.util.List;


import cn.happy.easybuy.entity.User;

public class UserPage {
    private int pageIndex=1; //当前默认显示第一页数据
    private int pageSize=3;//每页显示3条数据
    private int pageSum;//总记录数
    private int pageCount;//总页数
    private List<User>list;//保存消息分页信息的集合
    
    public int getPageIndex() {
        return pageIndex;
    }
    public void setPageIndex(int pageIndex) {
        this.pageIndex = pageIndex;
    }
    public int getPageSize() {
        return pageSize;
    }
    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }
    public int getPageSum() {
        return pageSum;
    }
    public void setPageSum(int pageSum) {
        this.pageSum = pageSum;
    }
    public int getPageCount() {
        return pageCount;
    }
    public void setPageCount(int pageCount) {
        this.pageCount = pageCount;
    }
    public List<User> getList() {
        return list;
    }
    public void setList(List<User> list) {
        this.list = list;
    }
    
}

这样一个用户的模块就做好了，接下来我们需要做的就是在用户的JSP页面中用于EL表达式进行页面展示了。如果需要增加自己的特点则添加jquery代码即可！

为了一些新手还是决定把jsp页面中的代码给出如下：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
