ATM小项目

ATM

1.项目简介

此项目是在学习过程中自己编写的Jframe界面项目，运用了SQL Server Management Studio 2012版本数据库，eclipse。

2、数据代码

1.数据库

此数据库脚本将创建ATM数据库、Users和Journals两个表，并插入初始数据。Users表用来储存用户基本信息，包括账号，密码，身份证，余额等。Journals表用来储存日志信息，我怕数据库日期转换麻烦就将日期定义成字符串类型。

use master go if exists(select * from sysdatabases where name='ATM') drop database ATM go create database ATM go use ATM go create table Users( userId int not null primary key, userName varchar(20) not null, userPassword int not null, userMoney money, mobile varchar(20), idcard varchar(20) not null, gender varchar(4) ) create table Journals( journalId int identity(1,1) not null primary key , Journal varchar(500),--记录 journalDate varchar(50), userId int not null constraint id_fk foreign key (userId) references Users (userId) ) insert into Users(userId,userName,userPassword,userMoney,mobile,idcard,gender)values (11111111,'dd',123456,2354,'13117380586','45646456454545','男') insert into Users(userId,userName,userPassword,userMoney,mobile,idcard,gender)values (123456,'dd',123456,2354,'1311738058','4564645645455','男') insert into Journals(Journal,userId)values('asd',11111111) --update Users set userName='',userPassword=0,userMoney=0.00,mobile='',idcard='',gender='',journal='' where userId=222 select Journal from Journals where userId=11111111 select * from Journals select * from Users

2.连接数据库

　　

package db; import java.sql.Connection; import java.sql.DriverManager; import java.util.Properties; public class DBConn { //设置常量 private static String DRIVER_CLASS_NAME="com.microsoft.sqlserver.jdbc.SQLServerDriver"; private static String DATABASE_URL="jdbc:sqlserver://localhost:1433;databaseName=ATM"; private static String USERNAME="sa"; private static String PASSWORD="123456"; private static Properties prop = null; static{ try { //1: 加载连接驱动，Java反射原理 Class.forName(DRIVER_CLASS_NAME); } catch (ClassNotFoundException e) { e.printStackTrace(); } } //创建数据库的连接 public static Connection getConntion(){ Connection conn = null; try { //2:创建Connection接口对象，用于获取数据库的连接对象。三个参数：url连接字符串 账号 密码 conn = DriverManager.getConnection(DATABASE_URL,USERNAME,PASSWORD); System.out.println("数据库连接成功！"); } catch (Exception e) { e.printStackTrace(); } return conn; } //测试是否连接成功 public static void main(String[] args) { getConntion(); } //关闭数据库的方法 public static void closeConnection(Connection conn){ if(conn!=null){ try { conn.close(); } catch (Exception e) { e.printStackTrace(); } } } }

3.user实体类

package entity; public class Users { private int userId;// *(必填) private String userName;// * private int userPassword;// * private double userMoney; private String mobile;// 手机号码 private String idcard;// * private String gender; private String journal; public String getJournal() { return journal; } public void setJournal(String journal) { this.journal = journal; } public int getUserId() { return userId; } public void setUserId(int userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public int getUserPassword() { return userPassword; } public void setUserPassword(int userPassword) { this.userPassword = userPassword; } public double getUserMoney() { return userMoney; } public void setUserMoney(double userMoney) { this.userMoney = userMoney; } public String getMobile() { return mobile; } public void setMobile(String mobile) { this.mobile = mobile; } public String getIdcard() { return idcard; } public void setIdcard(String idcard) { this.idcard = idcard; } public String getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } public Users(int userId, String userName, int userPassword, double userMoney, String mobile, String idcard, String gender,String journal) { super(); this.userId = userId; this.userName = userName; this.userPassword = userPassword; this.userMoney = userMoney; this.mobile = mobile; this.idcard = idcard; this.gender = gender; this.journal=journal; }   @Override public String toString() { return "Users [userId=" + userId + ", userName=" + userName + ", userPassword=" + userPassword + ", userMoney=" + userMoney + ", mobile=" + mobile + ", idcard=" + idcard + ", gender=" + gender + ", journal=" + journal + "]"; } /** * 必填的构造方法 * * @param userId * 用户id * @param userName * 用户姓名 * @param userPassword * 用户密码 * @param idcard * 身份证号 */ public Users(int userId, String userName, int userPassword, String idcard) { super(); this.userId = userId; this.userName = userName; this.userPassword = userPassword; this.idcard = idcard; this.userMoney=0.0; } }

 

4.编写DAO接口

package dao; import java.sql.SQLException; import java.util.List; import entity.Users; public interface UserDao { /** * 添加用户 * * @param user * @throws Exception */ void add(Users user) throws Exception; /** * 修改用户 * * @param user * @throws Exception */ void edit(Users user) throws Exception; /** * 删除用户 * * @param uid * @throws Exception */ void delete(int userId) throws Exception; /** * 查找用户 * * @param uid * @return * @throws Exception */ Users findById(int userId) throws Exception; /** * 用户列表 * * @return * @throws Exception */ List<Users> list() throws Exception; /** * 修改密码 * * @param userId * @param userPassword * 要修改的密码 * @throws Exception */ void changePassword(int userId, int userPassword) throws Exception; /** * 存款 * * @param userId * @param money * @param userPassword */ void deposit(int userId, double money) throws Exception; /** * 取款 * * @param userId * @param money * @param userPassword */ void withdraw(int userId, double money, int userPassword) throws Exception; /** * 转账 * * @param userId * @param accountId * 对方账户 * @param money * @param userPassword * @param accountName * 确认对方姓名 */ void transfer_accounts(int userId, int accountId, double money, int userPassword) throws Exception; /** * 生成日志 * * @param user * @param journal * 日志类型 * @throws Exception */ void journal(int userId, String journal) throws Exception; /** * 密码是否正确 * * @param userId * @param password * @throws Exception */ boolean isPassword(int userId, int password) throws Exception; /** * 用户是否存在 * * @param userId * @return * @throws Exception */ boolean haveCustomer(int userId) throws Exception; /** * 返回用户金额 * * @param userId * @return * @throws Exception */ double money(int userId) throws Exception; /** * 返回用户姓名 * * @param userId * @return * @throws Exception */ String userName(int userId) throws Exception; /** * 返回日志信息 * * @param userId * @param genre * 需要返回的数据种类 * @return */ List<String> checkJournal(int userId, String genre) throws Exception; /** * 返回当次使用ATM记录 * @param loginDate * @param userId * @return * @throws SQLException */ public List<String> dayJournal(String loginDate,int userId) throws SQLException; }

5.实现Dao接口
