Java图书管理系统附源码

Java图书管理系统附源码随着信息化的快速发展，图书馆已成为人们获取知识的重要场所。

为了提高图书馆的管理效率，本文介绍了一个基于Java语言的图书管理系统，并附带了完整的源代码。

该图书管理系统主要包括图书管理、读者管理、借阅管理、系统管理等模块。

系统采用B/S架构，以Java语言开发，运行在Windows平台上。

该系统具有操作简单、界面友好、维护方便等特点。

图书管理模块：实现图书的入库、修改、删除、查询等功能。

图书信息包括书名、作者、社、时间等。

读者管理模块：实现读者的入库、修改、删除、查询等功能。

读者信息包括姓名、性别、出生日期、方式等。

借阅管理模块：实现图书的借阅、归还、续借等功能。

借阅信息包括借书证号、书名、借阅时间、归还时间等。

系统管理模块：实现用户管理、权限管理等。

用户信息包括用户名、密码、角色等。

添加图书：管理员可以添加图书信息，包括书名、作者、社等。

添加读者：管理员可以添加读者信息，包括姓名、性别、方式等。

借阅图书：读者可以查询图书信息，并申请借阅。

管理员可以审核借阅申请，并决定是否同意。

归还图书：读者可以归还图书，管理员可以查询归还情况。

统计报表：系统可以生成各种报表，如图书借阅排行榜、读者借阅排行榜等。

由于篇幅限制，这里只提供部分源代码，完整源代码请参考附件。

随着信息技术的快速发展，图书馆作为信息和知识的聚集地，其传统的管理方式已经无法满足读者的需求。

为了提高图书管理效率，本文旨在研究基于Java的图书管理系统。

图书管理系统是图书馆的重要组成部分，它可以帮助图书馆工作人员和读者更加方便地管理图书资源。

传统的图书管理系统往往采用人工方式进行管理，这种方式不仅效率低下，而且容易出错。

因此，研究一种基于Java的图书管理系统势在必行。

基于Java的图书管理系统采用B/S架构，即浏览器与服务器之间的架构。

该架构将系统的业务逻辑和数据存储交由服务器处理，客户端通过浏览器访问系统。

Java图书管理系统-附源码

图书信息查询：
图书信息删除：
图书信息显示：
图书借阅：
图书归还：
分析总结:
本程序在数据库设计方面可以改为多张表存储的方式，用三张表来记录图书信息，借阅关系和学生信息，这样可以减少数据冗余，还可以增加一些其他功能，比如图书挂失等功能。由于刚刚接触到Java界面设计，所以本程序在界面设计方面还有有待改进的地方。
JMenuItem itemDelete = new JMenuItem();
JMenuItem itemSelect = new JMenuItem();
JMenuItem itБайду номын сангаасmBook = new JMenuItem();
JMenuItem itemReturn = new JMenuItem();
图书ID，图书名称，图书所有者，图书的状态，图书使用者（允许为空）均为varchar(50)类型，在Java中可以方便的查询。图书存储信息的具体内容如下图所示：
功能模块:
程序设计:
主框架设计：
主框架上方包含三个按钮，分别是“系统管理”、“图书信息管理”和“图书流通管理”，定义JMenuBar类的对象、JMenu类的对象和JMenuItem类的对象，分别表示菜单栏、菜单组和菜单选项，然后调用初始化函数，将不同类的对象通过setText()函数设定不同的文本，然后将其添加到窗口容器中。对每个按钮分别添加不同的消息监听，响应相应的消息，调用不同的类完成不同的功能。消息监听功能详见源代码bookMain类。
删除图书信息模块：
调用bookDel类的构造函数产生一个该类的对象，在初始化函数中显示信息输入对话框，提示用户输入要删除图书的ID。完成输入后，点击确定按钮，消息监听模块将调用bookBean的构造函数产生一个该类的对象，通过该对象调用bookBean的bookDel函数，执行删除的SQL语句，通过delete语句完成图书信息的删除功能。

图书信息管理系统
题目简述:
题目名称：图书信息管理系统
要求：使用图形用户界面，用数据库建立1或2个图书信息表，能连接数据库并实现查询、增加、删除、修改等功能。

需求分析:
图书信息管理系统应该具备图书的信息管理功能和流通管理
功能。

其中，信息管理功能包括查找，增加，修改，删除，显示全部信息等模块。

流通管理功能包括图书借阅，归还等模块。

因此分别设计各个模块，实现不同的功能。

数据结构:
用SQL Sever 建立数据库的表，用一张表存放图书的ID号码，图书名称，图书的所有者，图书状态，图书的使用者（允许为空）。

具体设计如下图所示：
图书ID，图书名称，图书所有者，图书的状态，图书使用者（允许为空）均为varchar(50)类型，在Java中能够方便的查询。

图书存储信息的具体内容如下图所示：
功能模块:
程序设计:
主框架设计：
主框架上方包含三个按钮，分别是“系统管理”、“图书信息管理”和“图书流通管理”，定义JMenuBar类的对象、JMenu 类的对象和JMenuItem类的对象，分别表示菜单栏、菜单组和菜单选项，然后调用初始化函数，将不同类的对象经过setText()函数设定不同的文本，然后将其添加到窗口容器中。

对每个按钮分别添加不同的消息监听，响应相应的消息，调用不同的类完成不同的功能。

消息监听功能详见源代码bookMain类。

图书信息管理模块包括增加图书，删除图书，编辑图书，查找图书和显示图书信息。

具体的方法实现在bookBean中实现，当
用户点击相应的按钮时，消息监听模块就会调用bookBean的构造函数产生一个bookBean的对象，然后经过对象调用bookBean类中的相应方法，完成事件的相应。

增加图书信息模块：
调用bookAdd类的构造函数产生一个该类的对象，在初始化函数中显示信息输入对话框，提示用户输入图书ID，图书名称和图书所有者，由于刚增加的图书没有被借阅，因此图书状态和图书使用者为默认值，分别为空闲和null，因此用户不必输入这两个属性值。

完成输入后，点击确定按钮，消息监听模块将调用bookBean的构造函数产生一个该类的对象，经过该对象调用bookBean的bookAdd函数，执行SQL语句，经过insert语句完成图书信息的增加插入功能。

删除图书信息模块：
调用bookDel类的构造函数产生一个该类的对象，在初始化函数中显示信息输入对话框，提示用户输入要删除图书的ID。

完成输入后，点击确定按钮，消息监听模块将调用bookBean的构造函数产生一个该类的对象，经过该对象调用bookBean的bookDel函数，执行删除的SQL语句，经过delete语句完成图书信息的删除功能。

修改图书信息模块：
点击按钮后调用bookEdit类的构造函数产生一个该类的对象，在初始化函数中显示信息输入对话框，提示用户输入要修改图书
的ID和其它图书信息，用户将信息输入完成后，点击确定按钮，消息监听模块将调用bookBean的构造函数产生一个该类的对象，经过该对象调用bookBean的bookEdit函数，执行修改的SQL语句，经过update语句完成图书信息的编辑功能。

查找图书信息模块：
点击按钮后调用bookSearch类的构造函数产生一个该类的对象，在初始化函数中显示信息输入对话框，提示用户输入要查找图书的ID，用户将信息输入完成后，点击确定按钮，消息监听模块将调用bookResult的构造函数产生一个该类的对象，经过该对象的构造函数，执行查找的SQL语句，经过select语句完成图书信息的查找功能，然后构造图标，将查询到的信息显示在图表中。

显示图书信息模块：
点击按钮后调用bookDisplay类的构造函数产生一个该类的对象，在该对象的构造函数中调用bookAllSearch函数，查询所有的图书信息，显示在表格中。

图书流通管理模块包含图书的借阅与归还功能，其实就是对数据库中的某一记录集的某一属性进行修改。

图书借阅模块：
用户输入要借阅的图书名称和本人姓名，点击确定后，将调用bookBean的构造函数产生一个对象，经过该对象调用bookBook函数，修改数据库中的信息，将图书状态属性变为已
借，将图书用户属性变为用户姓名，完成图书的借阅功能。

图书归还模块：
用户输入要归还的图书名称，点击确定后，将调用bookBean的构造函数产生一个对象，经过该对象调用bookReturn 函数，修改数据库中的信息，把图书的状态置为空闲，将图书用户置为空，从而完成图书的归还功能。
