# 前言 #

用到了IO流，集合和JavaSwing的实训小项目

--------------------

# 一、内容介绍 #

基本内容有：

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

主要用到的知识如下：

集合知识:用到List集合，来运输暂存数据 。  
接口:创建了BankController接口和UserController接口方便方法的调用和创建，分别用BankControllerimpl和UserControllerimpl类实现了它们。  
创建实体类：实用了创建方法的快捷方式。  
IO流：运用对象流的序列化和反序列化，将集合多次存入取出文件，方便数据更新的同时，能有效的保存用户和银行卡的信息。实现的此代码的类有AdminDao，BanksDao，UserDao。  
JavaSwing：把GUI组件合理的搭配和设计，添加到底层容器中，展现到窗口中，然后添加监听器，处理事件，完成每个界面的功能。此部分技术的运用都在com.baizhi.view包中

# 二、实现原理 #

## 登录页面 ##

首先设计的是登录页面，设置了手机号和密码两个可填项，同时设置两个按钮并且对其设置监听器，点击等录能够进入主页面，点击注册则跳转注册页面。

## 注册页面 ##

注册页面设置了一些用户的属性，没有格式要求，填写完整即可点击提交，把数据通过AdminDao对象流存入文件Admin.data，注册完成自动关闭页面，再次登录就可以使用该账号登录，点击取消关闭页面。  
![在这里插入图片描述][20210716150350415.png]

## 首页 ##

主页面包含左侧导航栏功能列表，显示功能，而功能这可以在界面中间部分展示出来，点击首页，返回首页，对应的界面是MainView。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 1]

## 用户信息 ##

有用户的信息展示，包括金额，修改金额后此处的金额也会随之变动，文字的前面都有图片标签。此页面的类为ShowUserView。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 2]

## 修改密码 ##

此功能是给登录的用户从新设置密码，通过UserDao类，获取所有用户，然后通过list集合存取用户，通过对list的遍历筛选，得到本用户的密码，然后调用setPwd对用户密码进行修改。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 3]

## 添加银行卡 ##

与注册用户相似，也是把得到的银行卡信息存到list中，如果已有银行卡，则先把以前银行卡的内容存到list中，然后再把新增的信息存入，这样就可以一次性存完，不用再考虑信息存入文件的内容覆盖的问题了。点击提交，存入数据。此页面的类为AddBanksView。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 4]

## 银行卡查看 ##

在此页面可以观察到此账户拥有的银行卡的信息，同样是通过BankDao获取此手机号拥有的银行卡信息list集合，然后通过遍历打印出来。此类的为ShowBanksView。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 5]

## 充值 ##

充值是从银行卡充钱到账户上，实现金额交换，将文本框获取的mony属性通过构造方法传入BanksServiceImpl类，完成后端的文件中的集合，然后通过遍历寻找，修改，然后点击充值，便会实现金额交换。此类为AddUsersMoneyView。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 6]

## 提现 ##

提现就是把账户上的钱提到银行卡上。  
提现和充值相同，把二者的方法，交换重写一遍就可以实现次功能。此类为AddBanksMoneyView。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 7]

## 银行卡转账 ##

首先要选择转入转出的对象是银行卡还是账户，然后分别输入银行卡或是账户的卡号和手机号，然后遍历所给的号是否存在，不存在会有弹框提示  
确定存在后，会对转出和转入方两个方法同时调用。实现金钱交换。  
此类为MoveMoneyView。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 8]

## 用户管理 ##

在这里可以显示注册过的所有用户，与银行卡查看同理，都是先得到所有用户信息的list，然后遍历打印出来。此类为ShowUserView。  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbTE5Nw_size_16_color_FFFFFF_t_70 9]
