Java Swing + MySQL 图书管理系统
Java Swing + MySQL 图书借阅管理系统

前言

项目是使用Java swing开发，界面设计比较简洁、适合作为Java课设设计以及学习技术使用。

• 语言：Java
• 界面：JavaSwing
• 数据库：MySQL 8.x

具体功能如下：
1、基础功能
（1）系统登录功能：用户可以通过用户名和密码登录系统。
（2）图书分类管理功能：管理员可以对于图书的类别进行增、删、改、查操作。
（3）图书信息管理功能：能够增、删图书，修改图书名称、类别、价格等信息。
（4）图书借阅管理功能：包括图书借出和图书归还等操作，设计功能时需要考虑逾期情况的判别和处理。
2、可选加分功能
（1）借阅记录查询功能：学生可以查看自己在某时间段之内的借阅记录；管理员可以按照学号查询学生的借阅记录。（ps：只有管理员能够增删改查图书内容，用户只有查找书的信息的权限）

一、项目展示

二、部分代码

1.Book

代码如下（示例）：

package entity;/*** BookManagementSystem* 图书** @author PlutoCtx* @version 2024/5/26 1:07* @email ctx195467@163.com* @since JDK17*/public class Book {/*** 图书id*/private int id;/*** 书名*/private String bookName;/*** 作者*/private String author;/*** 图书数量*/private int number;/*** 价格*/private Float price;/*** 图书类别*/private Integer bookTypeId;/*** 图书类别*/private String bookTypeName;/*** 描述*/private String bookDesc;public Book(String bookName, String author, Integer number, Float price, Integer bookTypeId, String bookDesc) {super();this.bookName = bookName;this.author = author;this.number = number;this.price = price;this.bookTypeId = bookTypeId;this.bookDesc = bookDesc;}public Book(int id, String bookName, String author, Integer number, Float price, Integer bookTypeId, String bookDesc) {super();this.id = id;this.bookName = bookName;this.author = author;this.number = number;this.price = price;this.bookTypeId = bookTypeId;this.bookDesc = bookDesc;}public Book(String bookName, String author, Integer bookTypeId) {super();this.bookName = bookName;this.author = author;this.bookTypeId = bookTypeId;}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getBookName() {return bookName;}public void setBookName(String bookName) {this.bookName = bookName;}public String getAuthor() {return author;}public void setAuthor(String author) {this.author = author;}public int getNumber() {return number;}public void setNumber(int number) {this.number = number;}public Float getPrice() {return price;}public void setPrice(Float price) {this.price = price;}public Integer getBookTypeId() {return bookTypeId;}public void setBookTypeId(Integer bookTypeId) {this.bookTypeId = bookTypeId;}public String getBookTypeName() {return bookTypeName;}public void setBookTypeName(String bookTypeName) {this.bookTypeName = bookTypeName;}public String getBookDesc() {return bookDesc;}public void setBookDesc(String bookDesc) {this.bookDesc = bookDesc;}public Book() {}public Book(int id,String bookName,String author,Integer number,Float price,Integer bookTypeId,String bookTypeName,String bookDesc) {this.id = id;this.bookName = bookName;this.author = author;this.number = number;this.price = price;this.bookTypeId = bookTypeId;this.bookTypeName = bookTypeName;this.bookDesc = bookDesc;}}

2.BookDao

代码如下（示例）：

package dao;import entity.Book;import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;/*** BookManagementSystem** @author PlutoCtx* @version 2024/5/26 9:27* @email ctx195467@163.com* @since JDK17*/public class BookDao {/*** 添加图书* @param connection    连接数据库* @param book  书籍* @return  preparedStatement.executeUpdate(),int* @throws Exception    how do I know*/public int add(Connection connection, Book book)throws Exception{String sql = "INSERT INTO book VALUES (null, ?, ?, ?, ?, ?, ?)";PreparedStatement preparedStatement = connection.prepareStatement(sql);preparedStatement.setString(1, book.getBookName());preparedStatement.setString(2, book.getAuthor());preparedStatement.setInt(3, book.getNumber());preparedStatement.setFloat(4, book.getPrice());preparedStatement.setInt(5, book.getBookTypeId());preparedStatement.setString(6, book.getBookDesc());return preparedStatement.executeUpdate();}/*** 查找书籍* @param connection    连接数据库* @param book  书籍* @return  preparedStatement.executeUpdate(), int* @throws Exception    how do I know*/public ResultSet list(Connection connection, Book book)throws Exception{StringBuilder stringBuffer = new StringBuilder("SELECT * FROM book b,bookType bt WHERE b.bookTypeId = bt.id");if(book.getBookName() != null &&!book.getBookName().equals("")){stringBuffer.append(" and b.bookName like '%").append(book.getBookName()).append("%'");}if(book.getAuthor() != null &&!book.getAuthor().equals("")){stringBuffer.append(" and b.author like '%").append(book.getAuthor()).append("%'");}if(book.getBookTypeId() != null && book.getBookTypeId()!=-1){stringBuffer.append(" and b.bookTypeId=").append(book.getBookTypeId());}PreparedStatement preparedStatement = connection.prepareStatement(stringBuffer.toString());return preparedStatement.executeQuery();}/*** 删除书籍* @param connection    连接数据库* @param id 书籍id号* @return  preparedStatement.executeUpdate(), int* @throws Exception    how do I know*/public int delete(Connection connection,String id)throws Exception{String sql = "DELETE FROM book " +"WHERE id = ?";PreparedStatement preparedStatement = connection.prepareStatement(sql);preparedStatement.setString(1, id);return preparedStatement.executeUpdate();}/*** 更新书籍* @param connection    连接数据库* @param book  书籍* @return  preparedStatement.executeUpdate(),int* @throws Exception    how do I know*/public int update(Connection connection,Book book) throws Exception{String sql = "UPDATE book " +"SET bookName = ?, author = ?, number = ?, price = ?, bookDesc = ?, bookTypeId = ? " +"WHERE id = ?";PreparedStatement preparedStatement = connection.prepareStatement(sql);preparedStatement.setString(1, book.getBookName());preparedStatement.setString(2, book.getAuthor());preparedStatement.setInt(3, book.getNumber());preparedStatement.setFloat(4, book.getPrice());preparedStatement.setString(5, book.getBookDesc());preparedStatement.setInt(6, book.getBookTypeId());preparedStatement.setInt(7, book.getId());return preparedStatement.executeUpdate();}/*** 判断书籍是否存在* @param connection    数据库连接* @param bookTypeId    书类号* @return  存在与否* @throws Exception    异常多了什么都有可能*/public boolean existBookByBookTypeId(Connection connection,String bookTypeId)throws Exception{String sql = "SELECT * FROM book WHERE bookTypeId = ?";PreparedStatement preparedStatement = connection.prepareStatement(sql);preparedStatement.setString(1, bookTypeId);ResultSet rs = preparedStatement.executeQuery();return rs.next();}}

3.DBUtil

package utils;import java.sql.Connection;
import java.sql.DriverManager;/*** BookManagementSystem* 数据库连接** @author PlutoCtx* @version 2024/5/26 8:06* @email ctx195467@163.com* @since JDK17*/public class DBUtil {/**数据库*/private String url = "jdbc:mysql://localhost:3306/BookBorrowingManagementSystem";/*** 用户名*/private String username = "root";/*** 密码*/private String password = "Shangxiao111";/*** 驱动名称*/private String jdbcName = "com.mysql.cj.jdbc.Driver";/*** 获取数据库连接* @return  返回连接* @throws Exception 没连上*/public Connection getConnection() throws Exception{Class.forName(jdbcName);Connection connection = DriverManager.getConnection(url, username, password);return connection;}/*** 关闭数据库连接* @param connection    数据库连接* @throws Exception    异常*/public void closeConnection(Connection connection) throws Exception{if (connection != null){connection.close();}}}

三、配置

1、idea直接导入解压文件夹
2、打开navicat等数据库可视化软件，运行sql文件夹下的数据库文件
3、修改DBUtil.java中的用户名、连接、密码（如果有必要的话）
4、运行Main
