Java-單機版的書店管理系統(練習設計模塊和思想_系列四)

編輯：JAVA綜合教程

Java-單機版的書店管理系統(練習設計模塊和思想_系列四)

本系列四介紹說明：

主要是添加了Uuid模塊，現在的uuid並不是由用戶輸入，而是我們通過軟件內部自動生成（通過唱票模式），uuid是不會產生重復的！

還有把主界面改了下，以後會改成登錄頁面的（待完善）。

現在進入其他模塊是通過菜單項進入的。

增加了圖書模塊！

注意：
每個模塊先寫哪個，我都是按照先後順序來上代碼的，從前往後依次寫代碼的。
注意是每個模塊！！！
先寫公共類和工具類再寫模塊的！
我公共類和工具類上傳在最後了，你看可以直接在左上角找目錄跳到那去看。
（限每個模塊內部）（因為還有公共類和工具類等）

軟件部分圖片：

現在先看軟件部分運行圖片：
待完成的主界面：現在通過菜單條：模塊進入其他的模塊：

用戶模塊主界面：

圖書模塊主界面：

添加用戶的界面：
相比上一系列，減少了uuid的輸入：
（其他如增刪改查的界面完全沒有動，這就是設計模塊的好處）

添加圖書的界面：

書店管理系統文件目錄：

主界面代碼：
