Java-单机版的书店管理系统(练习设计模块和思想_系列一 )：
http://blog.csdn.net/qq_26525215/article/details/51073546

本系列四介绍说明：

主要是添加了Uuid模块，现在的uuid并不是由用户输入，而是我们通过软件内部自动生成（通过唱票模式），uuid是不会产生重复的！

还有把主界面改了下，以后会改成登录页面的（待完善）。

现在进入其他模块是通过菜单项进入的。

增加了图书模块！

注意：
每个模块先写哪个，我都是按照先后顺序来上代码的，从前往后依次写代码的。
注意是每个模块！！！
先写公共类和工具类再写模块的！
我公共类和工具类上传在最后了，你看可以直接在左上角找目录跳到那去看。
（限每个模块内部）（因为还有公共类和工具类等）

软件部分图片：

现在先看软件部分运行图片：
待完成的主界面：现在通过菜单条：模块进入其他的模块：

用户模块主界面：

图书模块主界面：

添加用户的界面：
相比上一系列，减少了uuid的输入：
（其他如增删改查的界面完全没有动，这就是设计模块的好处）

添加图书的界面：
