Java图书管理系统CRUD展示
简介
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。
原题描述
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。
Append Find Remove Modify Show Quit > a ISBN: 9780439227148 Title: The Call of the Wild Author: Jack London Publisher: Scholastic Press Pub date: 2001/1/1 Price: 39.4 Append Find Remove Modify Show Quit > A ISBN: 9781772262902 Title: Oliver Twist Author: Charles Dickens Publisher: Engage Books Pub date: 2016/9/15 Price: 648 Append Find Remove Modify Show Quit > a ISBN: 9787515911076 Title: The Call of the Wild Author: Jack London Publisher: Aerospace Publishing House Pub date: 2016/5/1 Price: 29.8
若用户输入的日期信息不正确，则显示错误信息，并要求用户重新输入。
Append Find Remove Modify Show Quit > A ISBN: 9787501592401 Title: The Old Man and the Sea Author: Ernest Hemingway Publisher: Knowledge Press Pub date: 2016/2/30 Incorrect date! Please reenter: 2016/6/31 Incorrect date! Please reenter: 2016/8/1 Price: 25.8
若用户输入 S 或 s，则按书号升序排序，然后列表显示全部图书。
Append Find Remove Modify Show Quit > S ISBN--------- Title------------------------- Author-------------- Publisher--------------------- Pub-date-- Price--- 9780439227148 The Call of the Wild Jack London Scholastic Press 2001/01/01 39.40 9781772262902 Oliver Twist Charles Dickens Engage Books 2016/09/15 648.00 9787501592401 The Old Man and the Sea Ernest Hemingway Knowledge Press 2016/08/01 25.80 9787515911076 The Call of the Wild Jack London Aerospace Publishing House 2016/05/01 29.80
若用户输入 F 或 f，则输入书名，然后显示该书名的图书。如果没有对应的图书，则显示错误信息。
Append Find Remove Modify Show Quit > F Title: The Call of the Wild ISBN--------- Title------------------------- Author-------------- Publisher--------------------- Pub-date-- Price--- 9780439227148 The Call of the Wild Jack London Scholastic Press 2001/01/01 39.40 9787515911076 The Call of the Wild Jack London Aerospace Publishing House 2016/05/01 29.80 Append Find Remove Modify Show Quit > f Title: Gulliver's Travels Not found！
说明：输出查找结果时，不作排序操作。
若用户输入 R 或 r，则输入书号，然后将删除该书号的图书。如果没有对应的图书，则显示错误信息。
Append Find Remove Modify Show Quit > r ISBN: 9781772262902 Remove(y/n)? n Append Find Remove Modify Show Quit > S ISBN--------- Title------------------------- Author-------------- Publisher--------------------- Pub-date-- Price--- 9780439227148 The Call of the Wild Jack London Scholastic Press 2001/01/01 39.40 9781772262902 Oliver Twist Charles Dickens Engage Books 2016/09/15 648.00 9787501592401 The Old Man and the Sea Ernest Hemingway Knowledge Press 2016/08/01 25.80 9787515911076 The Call of the Wild Jack London Aerospace Publishing House 2016/05/01 29.80 Append Find Remove Modify Show Quit > R ISBN: 9780439227148 Remove(y/n)?

要求：用户回答是否删除时，必须回答 Y 或 N (大小写均可)。如果是其它字符，则显示错误信息，要求用户重新回答。
Append Find Remove Modify Show Quit > R ISBN: 9781772262902 Remove(y/n)? k Incorrect answer! Remove(y/n)? $ Incorrect answer! Remove(y/n)? N
若用户输入 M 或 m，则可以修改图书信息。首先按书号查找，然后重新输入该图书的信息。
Append Find Remove Modify Show Quit > m ISBN: 9787515911076 Modify(y/n)? y ISBN: 9787544724968 Title: The House on Mango Street Author: Sandra Heathneros Publisher: Yilin Press Pub date: 2012/1/1 Price: 30 Append Find Remove Modify Show Quit > M ISBN: 9787501592401 Modify(y/n)? n Append Find Remove Modify Show Quit > m ISBN: 9787515914145 Not found!
