模拟ATM机存取款管理系统

一、详细项目功能分析

1.功能菜单界面

通过ATMUISupport类实现系统的取款、存款、余额查询、转账、密码修改等界面显示功能。

代码如下：

private static void drawingBizUI() {System.out.println("\n\n");System.out.println("□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□");if(SystemEnter.atmSys.getTotal().doubleValue()>=SystemEnter.atmSys.getSingleWithdrawMin().doubleValue()){System.out.println("□□□□□ 取款请输入 1 □□□□□□□□□□□□□□□□□□□□□□□□□");}System.out.println("□□□□□ 存款请输入 2 □□□□□□□□□□□□□□□□□□□□□□□□□");System.out.println("□□□□□ 转账请输入 3 □□□□□□□□□□□□□□□□□□□□□□□□□");System.out.println("□□□□□ 查询请输入 4 □□□□□□□□□□□□□□□□□□□□□□□□□");System.out.println("□□□□□ 修改密码请输入 5 □□□□□□□□□□□□□□□□□□□□□□");System.out.println("□□□□□ 退卡请输入 6 □□□□□□□□□□□□□□□□□□□□□□□□□");System.out.println("□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□□");System.out.println("---------   请按以上提示输入回车继续    ---------");String action = BasicTools.getScanner().next();confimOperation(action);//调用确认用户选择项方法}

具体实现结果如下：

2.账号密码验证界面

（1）账号的有效性的实现：通过对AccountInfoConntrol类中的validdateAccountInfo()方法的调用实现快速准确识别用户的银行卡是否有效并给出相应的提示。

（2）密码的正确性的实现：通过对AccountInfoConntrol类中的validatePassword()方法的调用来实现密码验证该银行卡的密码与输入的的密码的一致性；如果密码输入错误则应提示重新输入密码，如果用户连续输入三次以上密码错误则对用户的银行卡实施锁定，锁定后的银行卡不能进行任何交易，必需持卡人持本人身份证到银行营业厅解除密码锁定并在锁定时给出系统提示“对不起，三次验证密码错误，此卡已被锁定，请持本人身份证到本行营业厅解除锁定”。

银行卡锁定代码：

SystemEnter.atmSys.modifyPasswordInputErrorNum();System.out.println("##########################################");System.out.println("##########    系统提示 密码不正确        ###########");System.out.println("##########################################");if(SystemEnter.atmSys.getAccount().getPasswordEnterErrorNumber() == 2){System.err.println("##########################################");System.err.println("#########  您已经2次输入密码错误      ############");System.err.println("#########  如果3次输入错误将锁定此卡     ##########");System.err.println("##########################################");continue;}if(SystemEnter.atmSys.getAccount().getPasswordEnterErrorNumber() == 3){System.err.println("##########################################");System.err.println("#########  您已经3次输入密码不错误      ###########");System.err.println("#########  此卡已被冻结 如果是您本人    ###########");System.err.println("########  请持有效证件到本行柜台办理    ###########");System.err.println("##########################################");/* 调用方法,锁定银行卡*/controller.lockAccount(SystemEnter.atmSys.getAccount().getAccount());flag = 1;break;}

lockAccount()方法的代码:

public int lockAccount(String cardNumber) throws Exception {int res = 0;String sql="UPDATE ACCOUNT_INFO SET FROZEN = 1 WHERE ACCOUNT = ?";Connection conn = null;PreparedStatement ps = null;try {conn = DataSourceManager.getConnection();ps = conn.prepareStatement(sql);//设置参数ps.setString(1, cardNumber);//执行查询语句res = ps.executeUpdate();} catch (SQLException throwables) {throwables.printStackTrace();}finally {DataSourceManager.close(ps);DataSourceManager.close(conn);}return res;}

密码的有效性代码：

if(!BasicTools.validDig(password) || password.length() != 6){// 密码格式不正确System.out.println("*********** 系统提示:密码必需是6位数字  *****************");continue;// 结束本次循环}

具体实现结果如下：

3.取款界面

（1）取款业务的实现：通过对AccountInfoDaoImp类中的countEverydayDrawingSum()方法的调用实现对该银行卡的取款业务

取款业务代码：

public Map<String, BigDecimal> countEverydayDrawingSum(String cardNumber) {Map<String, BigDecimal> map=new HashMap<String, BigDecimal>();String sql = "SELECT SUM(AMOUNT) everydayDrawingSum,COUNT(AMOUNT) everydayDrawingNum "+ "FROM BUSINESS "+ "WHERE ACCOUNTID = ? AND BUSID ='OUTCODE200' ";Connection conn = null;PreparedStatement ps = null;ResultSet set = null;try {conn = DataSourceManager.getConnection();ps = conn.prepareStatement(sql);//设置参数ps.setString(1, cardNumber);//执行查询语句set = ps.executeQuery();while (set.next()){BigDecimal bd=set.getBigDecimal("everydayDrawingSum");map.put("everydayDrawingSum",bd==null?new BigDecimal(0):bd);map.put("everydayDrawingNum",set.getBigDecimal("everydayDrawingNum"));}}catch (Exception e){e.printStackTrace();}finally {DataSourceManager.close(set);DataSourceManager.close(ps);DataSourceManager.close(conn);}return map;}

（2）余额验证功能：用户每次单笔取款操作时系统应检查用户余额去除实际用户取款后的金额是否低于卡中最低限额，如果低于最低限额则不执行本次取款操作并应提示用户余额不足。

代码实现：

// 账户余额不足
if(account.getBalance().subtract(money.add(new BigDecimal(poundage))).doubleValue() < 1)
{
mapRes.put("res",new Double(-1));
return mapRes;
}

（3）金额限制功能实现：取款界面应提供用户输入框接收用户输入的取款金额；取款金额应不大于每次单笔交易的最高限额并且累计不能超出24小时的最高限额，取款金额限定整百数额，不支持十位金额取款操作。

// 累计取款总额超出ATM最高限制
if(new BigDecimal(sum).add(money).doubleValue()
{
SystemEnter.atmSys.getEverydayWithdrawMax().doubleValue())
{
mapRes.put("res",new Double(-2));
return mapRes;
}
// 累计取款次数已超出ATM最高限制
if(num == SystemEnter.atmSys.getWithdrawFrequencyMax().intValue())
{
mapRes.put("res",new Double(-3));
return mapRes;
}
// 累计取款总和超出银行卡每日取款累计和上限
if(sum + money.doubleValue() > account.getTodayOutMax().doubleValue() )
{
mapRes.put("res",new Double(-4));
return mapRes;
}
//验证取款金额是否数字
if(!BasicTools.validDig(money)){
System.err.println("########## 系统提示 必需是数字 ###########");
System.err.println("##### 继续取款请输入1 返回主菜单请输入2 #####");
if("1".equals(BasicTools.getScanner().next())){continue;//结束本次循环
}
break;
}
//验证取款金额是否大于余额
else if(Integer.parseInt(money)%100!=0){
System.err.println("########## 系统提示 取款金额必需是整百数字 ###########");
System.err.println("##### 继续取款请输入1 返回主菜单请输入2 #####");
if("1".equals(BasicTools.getScanner().next())){continue;//结束本次循环
}break;
}

具体实现结果：

4.余额查询界面

系统应提供余额查询功能，在用户选择查询余额操作后应正确显示用户卡内的余额。

代码实现：

public AccountInfo BusinessQuery(String account) {String sql = "SELECT * FROM ACCOUNT_INFO WHERE ACCOUNT = ?";AccountInfo account1=null;Connection conn = null;PreparedStatement ps = null;ResultSet set = null;try {conn = DataSourceManager.getConnection();ps = conn.prepareStatement(sql);//设置参数ps.setString(1, account);//执行查询语句set = ps.executeQuery();while (set.next()){account1=new AccountInfo();account1.setAccount(set.getString("ACCOUNT"));account1.setId(set.getString("ID"));account1.setPassword(set.getString("PASSWORD"));account1.setAccountType(set.getShort("ACCOUNT_TYPE"));account1.setBalance(set.getBigDecimal("BALANCE"));account1.setTodayOutMax(set.getBigDecimal("TODAY_OUT_MAX"));account1.setTodayTaMax(set.getBigDecimal("TODAY_TA_MAX"));account1.setUserId(set.getString("USERID"));account1.setBankId(set.getString("BANKID"));account1.setFrozen(set.getShort("FROZEN"));account1.setLocation(set.getString("LOCATION"));account1.getCreateTime(set.getDate("CREATETIME"));}}catch (Exception e){e.printStackTrace();}finally {DataSourceManager.close(set);DataSourceManager.close(ps);DataSourceManager.close(conn);}return account1;}

实现结果：

5.转账功能界面

转账功能：通过对AccountInfoDaoImp类中的TransferAccounts()方法的调用实现从本卡转到本行其他账户或其它行账户的交易功能

实现代码：

public int TransferAccounts(String account, BigDecimal amount, double serviceCharge,String account2) {int res = 0;/* 更新账户余额SQL*/String sql0 = "UPDATE ACCOUNT_INFO SET BALANCE = BALANCE-?-? WHERE ACCOUNT = ?";/* 添加交易记录SQL*/String sql2 = "INSERT INTO BUSINESS2 (ID,ACCOUNTID1,BUSID1,AMOUNT1,"+"ACCOUNTID2,BUSID2,AMOUNT2,POUNDAGE,DESCRIPTION)"+"VALUES(?,?,?,?,?,?,?,?,?)";/* 更新ATM余额SQL*/String sql3 = "UPDATE ATM SET TOTAL = TOTAL - ? WHERE ID = ?";/* 更新账户余额SQL*/String sql4 = "UPDATE ACCOUNT_INFO SET BALANCE = BALANCE+? WHERE ACCOUNT = ?";Connection conn = null;PreparedStatement ps = null;PreparedStatement ps2 = null;PreparedStatement ps3 = null;PreparedStatement ps4 = null;try {conn = DataSourceManager.getConnection();conn.setAutoCommit(false);// 关闭自动提交ps = conn.prepareStatement(sql0);ps.setBigDecimal(1,amount);ps.setDouble(2,serviceCharge);ps.setString(3, account2);res += ps.executeUpdate();ps2 = conn.prepareStatement(sql2);ps2.setString(1, UUID.randomUUID().toString());ps2.setString(2,account2);ps2.setString(3,"OUTCODE200");ps2.setBigDecimal(4, amount);ps2.setString(5,account);ps2.setString(6,"INCODE200");ps2.setBigDecimal(7, amount);ps2.setDouble(8,serviceCharge);ps2.setString(9,"ATM"+account2+"向"+account+"转账");res += ps2.executeUpdate();ps3 = conn.prepareStatement(sql3);ps3.setBigDecimal(1, amount);ps3.setString(2, SystemEnter.atmSys.getId());res += ps3.executeUpdate();ps = conn.prepareStatement(sql4);ps.setBigDecimal(1,amount);ps.setString(2, account);res += ps.executeUpdate();} catch (Exception e) {try {System.out.println("撤销事务");conn.rollback(); // 撤销事务操作} catch (SQLException e1) {e1.printStackTrace();}e.printStackTrace();}finally{DataSourceManager.close(ps);DataSourceManager.close(ps2);DataSourceManager.close(conn);}return res;}

（2）验证功能：转出金额是否符合银行规定(最高转账金额，余额是否充足)。

代码部分：

//转账的银行卡1余额不足
if(SystemEnter.atmSys.getAccount().getBalance().subtract((money).add(new BigDecimal(poundage))).doubleValue() < 1){
mapRes.put("res",new Double(-1));
return mapRes;
}if(new BigDecimal(sum).add(money).doubleValue() >
SystemEnter.atmSys.getEverydayTurnOutMax().doubleValue()){
mapRes.put("res",new Double(-2));
return mapRes;
}
if(num == SystemEnter.atmSys.getWithdrawFrequencyMax().intValue()){
mapRes.put("res",new Double(-3));
return mapRes;
}
if(sum + money.doubleValue() > account.getTodayTaMax().doubleValue() ){
mapRes.put("res",new Double(-4));
return mapRes;
}
if (res.get("res").intValue()==4){
System.out.println("☆☆☆☆☆☆☆☆ 恭喜您,本次业务交易成功! ☆☆☆☆☆☆☆☆");
System.out.println("☆☆☆☆☆☆☆ 本次转账 "+money+"元☆☆☆☆☆☆☆☆");
SystemEnter.atmSys.modifyAccountBalance(new BigDecimal(money),-1);
System.out.println("ATM当前余额"+SystemEnter.atmSys.getTotal().doubleValue());
System.out.println("银行卡当前余额"+(SystemEnter.atmSys.getAccount().getBalance().doubleValue()-res.get("poundage")));
}else if (res.get("res").intValue()==-1){
System.out.println("☆☆☆☆☆☆☆☆ 本次操作时跨行转账,收取手续费后余额不足! ☆☆☆☆☆☆☆☆");
}else if (res.get("res").intValue()==-2){
System.out.println("☆☆☆☆☆☆☆☆ 每日累计转账总额已超出ATM最高上限☆☆☆☆☆☆☆☆");
}else if (res.get("res").intValue()==-3){
System.out.println("☆☆☆☆☆☆☆☆ 每日累计次数已超过ATM最高限制 ☆☆☆☆☆☆☆☆");
}else if (res.get("res").intValue()==-4){
System.out.println("☆☆☆☆☆☆☆☆ 每日累计转账总和超出最高限制 ☆☆☆☆☆☆☆☆");
}

实现结果：

6.修改密码界面

（1）修改密码功能：通过对AccountInfoDaoImp类中的TransferAccounts()方法的调用实现密码修改。

public int ModifyPasswordy(String account, String password1) {int res = 0;String sql="UPDATE ACCOUNT_INFO SET PASSWORD = ? WHERE ACCOUNT = ?";Connection conn = null;PreparedStatement ps = null;try {conn = DataSourceManager.getConnection();ps = conn.prepareStatement(sql);//设置参数ps.setString(1, password1);//执行查询语句ps.setString(2, account);//执行查询语句res = ps.executeUpdate();} catch (SQLException throwables) {throwables.printStackTrace();}finally {DataSourceManager.close(ps);DataSourceManager.close(conn);}return res;}

（2）验证密码格式功能：

System.out.println("************ 请输入新的6位数字密码 **************");
String password2 =BasicTools.getScanner().next();
if(!BasicTools.validDig(password2) || password2.length() != 6){// 密码格式不正确
System.out.println("*********** 系统提示:密码必需是6位数字  *****************");
continue;// 结束本次循环
}else{
if(password1.equals(password2)){
int map=controller.ModifyPasswordy(SystemEnter.atmSys.getAccount().getAccount(),password1);
if(map==1){
System.out.println("☆☆☆☆☆☆☆☆ 恭喜您,本次密码修改成功! ☆☆☆☆☆☆☆☆");
}
}else {
System.out.println("*********** 系统提示:两次密码输入不一致  *****************");
continue;// 结束本次循环
}
}

实现结果：
