Java设计模块系列之书店管理系统单机版(二)

Java-单机版的书店管理系统(练习设计模块和思想_系列 一 )： https://www.jb51.net/article/91004.htm

介绍

小提示：上面一点有一个目录，可以快速定位到自己需要看的类。
今天对前面的代码有了小小的修改，让代码更加完善了一点。
至于用户唯一标识码uuid，会在以后修改成程序内部生成的，
现在的uuid还是由用户自己设置。

今天对这个程序，添加了用户界面的表现层的一部分，增加了公共类 枚举，
下面贴出目前我写的这个程序的全部代码：我会逐渐的写完这个程序的，请大家放心！（需要实现的功能在这个书店管理系统的系列一可以找到，我为这个系列的文章已经分类了，方便大家寻找）
这个系列的博客是不会断的。

现在的代码分层：

现在的程序运行后的图片：

我按照从目录上面到下面的顺序贴出代码：
请注意！这个代码顺序并不是我写代码的顺序！
如果你们要参考我的写，请不要按照我贴的代码的顺序。
应该先写公共类，工具类。
再次：数据层类—>逻辑层类—>表现层类
现在程序运行后的部分图片：

今天就写到这里的，未完待续。。。
目前的添加有一个小bug，就是添加用户时，什么都不输入，
只选择用户类型，也能创建！下次我会修复的。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持考高分网。
