前言

银行用户管理系统是由我的另一篇博客项目 Java实训项目——网银管理系统改编而来。 与之不同的是，这个小项目新增了 转账流水功能， 并且运用了 集合，JavaSpring，mysql数据库和JDBC。 虽然大同小异，但亦有可取之处。

---

一. 功能

1. 登陆

2. 注册

3. 首页

4. 个人信息显示

5. 修改密码

6. 添加银行卡

7. 银行卡查看

8. 充值

9. 提现

10. 转账

11. 用户管理

12. 转账流水

把用户信息，银行卡信息和转账流水（包括充值，提现和转账）都存入数据库之中，在根据功能合理的使用这些数据。
详细的功能介绍在上一篇项目博客中已经介绍过了 ——网银管理系统。

二. 代码

银行卡数据

转账流水数据
