这篇文章是针对一个c++的编程题,进行的java的改变,然后在那个基础之上加上了一个网页的前端,主要的参考文章是这两篇,看完之后,就会发现,其实这个,大部分项目都是图书管理系统的简单变化而成的。

在创建项目的那些地方,在springboot+vue+mybatis-plus+axios实现商品的CRUD这篇文章里面,已经写好了,怎么创建一个springboot项目可以参考这篇文章。
这个题的原题是这样的,是一个C++的期末考试题目。
请设计一个简单的图书目录管理系统(初级版)。
图书目录信息包括:
统一书号(不超过13字符)
书名(不超过30字符)
作者(不超过20字符)
出版社(不超过30字符)
出版日期(包括:年、月、日)
价格(精确到分)
注意:为了保证运行窗口能正确地显示,请右击运行窗口,修改“属性”:
在“选项”选项卡中,选中“使用旧版本控制台”
在“字体”选项卡中,选择“8×16”“点阵字体”
在“布局”选项卡中,将屏幕窗口宽度均设为“120”。
具体需求如下:
显示如下的主菜单:
Append Find Remove Modify Show Quit > _
如果用户输入 A 或 a、F 或 f、R 或 r、M 或 m、S 或 s,则可完成相应的操作。如果用户输入其它字符,则显示错误信息。
程序将反复显示主菜单,让用户持续工作。如果用户输入 Q 或 q,则程序结束。
Append Find Remove Modify Show Quit > Q
Thank you! Goodbye!
若用户输入其它字符,则显示错误信息。
Append Find Remove Modify Show Quit > B
Incorrect choice!
Append Find Remove Modify Show Quit > 9
Incorrect choice!
Append Find Remove Modify Show Quit > +
Incorrect choice!
若用户输入 A 或 a,则可以输入新书的信息,将其添加到图书目录中。
