java实现信息管理系统之宿舍水电管理
实验要求
宿舍水电管理系统
1，宿舍水电基本信息管理（增删改查）
2，水电抄表管理（增删改查）
3，水电收费管理（增删改查）
4，考虑管理员、住户两种用户，要求有登录功能
实验六：
Java 面向对象及GUI 程序设计（2）第 8~9 周，每周提交报告与程序实验目的
1，掌握面向对象的思想，用面向对象的思维分析设计 Java 程序；
2，掌握Java 类的设计方法，对象的构建和使用
3，掌握Java 的接口、继承与多态
4，掌握Swing 常用组件
5，掌握Java 文件读写方法
成果展示
1，只实现了管理员的增删改查（但其他类似）
2，删除后刷新表格数据不变或者重复加表格最后一个但文件已经删除指定信息
3，背景图片随窗口大小变化没有实现成功
需求分析
实验要求的系统不大明确，所以按基本常识简单分析一下系统actor:管理员和住户
管理员
超级管理员（Admin）：
可以对管理员和住户管理，可以对水电费账单管理（这个实验里没实现管理员权限的限制但很简单就是要获取当前用户然后把当前用户传入要进入的UI（界面）里，就可以对其进行操作限制）
一般管理员：
只能管理住户
住户（Household）：
可以查看修改自己信息，可以充值缴费
水电费管理和抄表管理我简单合到一起，就是水电费账单，管理员在抄表信息录入后可以勾选是否缴费。
账单（Bill）;
管理员可对其增删改查，用户只能查看
以上只是简单的分析，肯定不合理，这也导致我在后面编码时老是重构代码。
系统架构
系统架构在最初的文本界面和AWT界面里我没有这个概念所以代码写的很乱，这次实验老师明确要求要分层故特地查了系统架构方面的知识和复习了C#实习的项目
一篇博客写得比较简洁易懂
在C#实习里实习老师给我们介绍的是5层架构模式：
UI——>Bll——>Dal——>DataBase（——>Model对model操作）
所以我借助demo架构我的系统
简单说一下个人对这个架构模式的理解，（可能不对@~@）
UI(user interface) 就是界面，充当系统和用户的交互接口（它把用户的请求发送给系统，系统响应请求后通过UI给用户一个答复）
model 是对你要操作的对象的一个描述/一个封装，里面包含有这个对象的属性和set/get方法（属性是private的别的类访问不了因此要这些方法【个人理解】）
DAL (data access level)数据访问层，访问database里的东西。
BLL （business logic level）业务逻辑层 实现业务逻辑的，比如用户登陆，UserBll里就有一个方法UserBLL.login()供UI调用
以我的系统来分析：
创建各个层，数据库用文本文件代替（为了代码的简洁及重复调用要建一个类Filehelper1专门操作文件的读写创建删除操作）
数据操作，我的大概思路是这样：
在dal里建立一个ArrayList ,把文件读出来放入里面，删除文件，建一个相同路径的文件，遍历数组对数据做你想要的操作后再全部放入文件中。
文件操作选择对象流操作，把一个对象序列化后放入文件。
下面是对象流读取文件的类（测试没采用单元测试简单的加main函数测试） 我是在网上查了两种方法组合调试编写成自己的FileFelper1，一个是百度知道另一个是具体忘了就不写链接出来了。

}UI设计建议
老师建议先不用windowbuilder插件，但个人建议先用再说，不然太打击自信心了，敲半天代码表达不了自己想要的界面！
主窗口一般用JFrame,布局用boder布局就是分东西南北中那个，之后各个方位（如果用到）里用group布局这种布局可以任意拖动，比较简单好用。
实验总结
这次实验里学得比较多，对于面向对象编程，接口，多态得到质的理解。
面向对象：比如Admin。在UI里获取admin的部分属性，然后封装成Admin ad =Admin(,)里面的参数就是UI里的之后把ad交给下一层去处理，反过来也是这样。
多态：在编码时自己曾特别疑惑，searchAdmin(),这里的参数到底是什么呢？是Admin?还是Admin的一个或多个属性？
最后在searchAdmin(String account),searchAdmin(String account,String password)里豁然开朗。
这样理解，把传入的参数都看成是对象。记得Python好像就是所见皆为对象。
