JavaSe进阶项目——图书管理系统

一、图书管理系统需求分析

一、背景分析

​ 一直以来人们使用传统的人工方式管理图书资料。这种方式存在着许多缺点，如效率低、保密性差且较为繁琐。图书管理作为计算机应用的一个分支，有着手工管理无法比拟的优点，如检索迅速、查找方便、可靠性高、存储量大、保密性好、寿命长、成本低等。这些优点能够极大地提高图书管理的效率。因此，开发一套能够为用户提供充足的信息和快捷的查询手段的图书管理系统，将是非常必要的，也是十分及时的。

二、功能模块分析

上图为图书馆管理系统的功能模块概览，该图书馆管理系统主要分为两大模块：

一、管理员模块

1.1、用户管理

模块功能	说明
管理员登录	用户输入用户名和密码进行登录，并作出相应提示，登录的同时需要对其身份进行验证，判断此用户为管理员还是普通账户，如果为管理员，则跳转到管理员界面，如果为普通用户则跳转到普通用户界面。
管理员添加	在管理员界面，管理员选择管理员添加操作，可进行管理员添加，添加时需要进行重名检测。
普通用户列表查询	选择普通用户列表查询，可查询所有已经注册的普通用户的基本信息列表（密码等隐私信息不可显示）。
用户账户禁用与开启	管理员可对指定的普通用户进行账号禁用和开启操作，用户账号禁用后则不能进行登录。

1.2、书籍管理

模块功能	说明
书籍添加	管理员在书籍管理界面进行书籍的添加，书籍添加时，书籍名可以重复，但是需要书籍编号作为主键。 添书籍基础信息时，要指定此书籍的类别编号，可单独定义一张书籍类别表和书籍表关联，但是此类别表事先定义好数据，不作任何修改。
书籍删除	管理员通过书籍编号可对指定的书籍进行删除，前提是这本书处于无人借阅状态，否则删除失败。
书籍修改	管理员通过书籍编号可对指定书籍的信息进修改。
书籍列表查询	进行书籍列表查询时，需要管理员选择要查询的字段（如书籍名、书籍作者、书籍类型），查询时都是进行模糊查询。
书籍详情查看	根据书籍编号进行书籍详细信息显示。

二、普通用户模块

2.1、用户个人信息管理

模块功能	说明
用户登录	用户输入用户名和密码进行登录，并作出相应提示，登录的同时需要对其身份进行验证，判断此用户为管理员还是普通账户，如果为管理员，则跳转到管理员界面，如果为普通用户则跳转到普通用户界面。
用户注册	普通使用此图书馆平台时，需要进行用户注册，注册时，需要对用户名进行重名检测。
个人基础信息查询	用户登录后，可查询当前用户的基础信息（不包含密码等敏感信息）。
个人基础信息修改	用户登录后，可对当前基础信息进行修改，用户名不可修改。
密码修改	修改密码等敏感信息，需要单独用页面进行，修改时，需要用输入原始密码进行验证。

2.2、书籍管理

模块功能	说明
书籍列表查询	进行书籍列表查询时，需要用户选择要查询的字段（如书籍名、书籍作者、书籍类型），查询时都是进行模糊查询。
书籍详细查询	用户通过输入书籍编号，查询当前书籍的详细信息。
书籍借阅	用户通过输入书籍编号进行相应书籍借阅，每次借阅行为只能借阅一本书籍。借阅时，如果此书籍状态为不可借阅，则借阅失败；如果此书籍库存数量为0，则借阅失败；借阅成功，则当前书籍库存数量为-1。
书籍归还	在书籍归还界面，用书输入要归还的书籍编号进行书籍归还，然后将相应书籍的借阅状态修改成已归还，并将相关书籍的库存数量+1。
个人借阅历史	通过此界面可查看自己借阅过的书籍列表，显示时按照借阅时间排序，并且显示此书籍的借阅状态（已归还、借阅中）

三、表结构

1、用户表（t_user)

字段名	数据类型	说明
user_id	int	用户id，主键
user_name	varchar	用户名，唯一，非空
password	varchar	用户密码，非空
age	int	年龄
gender	varchar	性别
phone	varchar	电话号码
address	varchar	地址
user_state	int	用户账号状态： 0：正常 ， 1：禁用
role	int	用户性质：0：管理员，1：普通用户

2、书籍表（t_book）

字段名	数据类型	说明
book_id	int	书籍编号，主键
book_name	varchar	书籍名，非空
book_author	varchar	书籍作者，非空
book_num	int	书籍库存数量，非空
book_category	int	书籍类别，该字段值和书籍类别表中的类别编号，非空
book_state	int	书籍是否可借阅状态： 0：可借阅 ， 1：不可借阅

3、书籍类别表（book_category）

字段名	数据类型	说明
category_id	int	书籍类别编号，主键
category_name	varchar	书籍类别名，非空（如政治、军事、体育、经济等）

4、借阅信息表（t_borrowing_info）

字段名	数据类型	说明
borrowing_info_id	int	当前这条借阅数据的id，主键， 用户每借阅一本书籍时，会在当前借阅表中生成一条数据
user_id	int	发生借阅行为的用户id，非空
book_id	int	被借阅的书籍的id，非空
borrowing_state	int	借阅状态： 0：借阅中 1：已归还
borrowing_time	datetime	借阅时间
giveback_time	datetime	归还书籍时间，初始为空，归还书籍后，显示最后还书时间

二、MVC设计模式

​ MVC 模式（Model–view–controller）是软件工程中的一种软件架构模式，它把软件系统分为三个基本部分：模型（Model）、视图（View）和控制器（Controller）。

​ MVC 模式的目的是实现一种动态的程序设计，简化后续对程序的修改和扩展，并且使程序某一部分的重复利用成为可能。除此之外，MVC 模式通过对复杂度的简化，使程序的结构更加直观。软件系统在分离了自身的基本部分的同时，也赋予了各个基本部分应有的功能。专业人员可以通过自身的专长进行相关的分组：

• 模型（Model）：程序员编写程序应有的功能（实现算法等等）、数据库专家进行数据管理和数据库设计(可以实现具体的功能)；
• 控制器（Controller）：负责转发请求，对请求进行处理；
• 视图（View）：界面设计人员进行图形界面设计。

MVC 模式的图形描述如下：

MVC模式中三个组件的详细介绍如下：

• 模型（Model）：用于封装与应用程序的业务逻辑相关的数据以及对数据的处理方法。“Model”有对数据直接访问的权力，例如对数据库的访问。“Model”不依赖“View”和“Controller”，也就是说， Model 不关心它会被如何显示或是如何被操作。但是 Model 中数据的变化一般会通过一种刷新机制被公布。为了实现这种机制，那些用于监视此 Model 的 View 必须事先在此 Model 上注册，由此，View 可以了解在数据 Model 上发生的改变。（比如：观察者模式（软件设计模式））；
• 视图（View）：能够实现数据有目的的显示（理论上，这不是必需的）。在 View 中一般没有程序上的逻辑。为了实现 View 上的刷新功能，View 需要访问它监视的数据模型（Model），因此应该事先在被它监视的数据那里注册；
• 控制器（Controller）：起到不同层面间的组织作用，用于控制应用程序的流程。它处理事件并作出响应。“事件”包括用户的行为和数据 Model 上的改变。

从MVC模式的一般理解来看，视图层与模型层是存在直接联系的，并且模型层的变化会通过视图层反映出来，这确实是MVC模式的标准理解，不过在我目前接触到的实际应用中，更多的情况时，视图层与模型层是通过控制层联系起来的，两者之间并无直接的联系，三者之间的关系更类似下图所示：

结合MVC模式的标准解释来看，上述模式可能是MVC模式的一种变型使用。

三、实际开发

一、项目结构介绍

首先先看一下我的项目结构：

项目各包作用：

包名	作用
lib	根据mysql版本下载的数据库连接器 具体下载地址为：https://mvnrepository.com/artifact/mysql/mysql-connector-java
util	存放了工具包，此项目中具体存放了Jdbc工具类
cn.egret	存放所有项目文件的总包
dao	存放和数据库交互的Java文件
entity	存放实体类
service	进一步封装了dao包的工具函数，引用dao包的函数
各impl包	存放了各包接口的实现类
controller	存放了控制器类，具体封装了各功能函数（如登录、注册等）
page	存放了各主要页面
smallPage	存放了小页面（面板）
smallPage.admin	存放了管理员界面的小页面
smallPage.common	存放了普通用户界面的小页面
test	存放了dao包各函数的测试类

二、开发流程

一、创建数据库

利用Navicat Premium 15新建数据库library，然后根据需求设计各表，最终效果如下图所示：

以下是数据库设计代码，由Navicat Premium 15自动生成，可保存后在自己的数据库中运行，便可得到以上各表：

/*

SET FOREIGN_KEY_CHECKS = 1;

二、添加数据库连接器

在项目中新建lib文件夹，然后在网上下载和自己mysql数据库相对应的连接器，放到lib文件夹中，然后右击连接器文件—>Build Path—>Add to Build Path

三、创建文件jdbc.properties

新建文件jdbc.properties，在里面填上以下内容：

driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=UTF-8&userSSL=true&serverTimezone=UTC 
username=root #数据库账户
password=123456 #数据库密码

四、创建工具类JdbcUtil.java

在util包中新建工具类JdbcUtil.java，以下为代码：

package cn.egret.util;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.net.URL;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Properties;

public class JdbcUtil {
	private static String url;
	private static String username;
	private static String password;
	private static String driver;

	static {
		// 读取资源文件,获取值
		// 创建properties集合类
		Properties properties = new Properties();
		try {
			// 获取src路径下的文件的⽅式--->ClassLoader 类加载器
			ClassLoader classLoader = JdbcUtil.class.getClassLoader();

			// URL表示统⼀资源标识符
			URL res = classLoader.getResource("jdbc.properties");
			String path = res.getPath();
			System.out.println(path);

			// 2. 加载文件
			properties.load(new FileReader(path));
			url = properties.getProperty("url");
			username = properties.getProperty("username");
			password = properties.getProperty("password");
			driver = properties.getProperty("driver");
			Class.forName(driver);
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	/**
	 * 获取连接
	 *
	 * @return 连接对象
	 */

	public static Connection getConnection() throws SQLException {
		return DriverManager.getConnection(url, username, password);
	}

	/***
	 * DML操作（增删改） 1.获取连接数据库对象 2.预处理 3.执行更新操作
	 * 
	 * @param sql
	 * @param obj
	 */
	// 调用者只需传入一个sql语句，和一个Object数组。该数组存储的是SQL语句中的占位符
	public static boolean executeUpdate(String sql, Object... obj) {

		Connection con = null;
		try {
			con = getConnection(); // 调用getConnection()方法连接数据库
		} catch (SQLException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}

		PreparedStatement ps = null;
		try {
			ps = con.prepareStatement(sql);// 预处理

			for (int i = 0; i < obj.length; i++) {// 预处理声明占位符
				ps.setObject(i + 1, obj[i]);
			}
			int count = ps.executeUpdate();// 执行更新操作
			
			if(count > 0) {
				return true;
			}
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {

			close(null, ps, con);// 调用close()方法关闭资源
		}
		return false;
	}

	/***
	 * DQL查询 Result获取数据集
	 * 
	 * @param sql
	 * @param obj
	 * @return
	 */
	public static List<Map<String, Object>> executeQuery(String sql, Object... obj) {
		Connection con = null;
		try {
			con = getConnection();
		} catch (SQLException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		ResultSet rs = null;
		PreparedStatement ps = null;
		
		try {
			ps = con.prepareStatement(sql);
			for (int i = 0; i < obj.length; i++) {
				ps.setObject(i + 1, obj[i]);
			}
			rs = ps.executeQuery();
			
			// new 一个空的list集合用来存放查询结果
			List<Map<String, Object>> list = new ArrayList<>();
			
			// 获取结果集的列数
			int count = rs.getMetaData().getColumnCount();
			
			// 对结果集遍历每一条数据是一个Map集合，列是key,值是value
			while (rs.next()) {
				// 一个空的map集合，用来存放每一行数据
				Map<String, Object> map = new HashMap<String, Object>();
				for (int i = 0; i < count; i++) {
					Object ob = rs.getObject(i + 1);// 获取值
					String key = rs.getMetaData().getColumnName(i + 1);// 获取k即列名
					map.put(key, ob);
				}
				list.add(map);
			}
			return list;
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} finally {

			close(rs, ps, con);
		}

		return null;

	}

	/**
	 * 释放资源
	 * 
	 * @param rs
	 * @param ps
	 * @param conn
	 */
	public static void close(ResultSet rs, PreparedStatement ps, Connection conn) {
		if (rs != null) {
			try {
				rs.close();
			} catch (SQLException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();

			}
			if (ps != null) {
				try {
					ps.close();
				} catch (SQLException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
			if (conn != null) {
				try {
					conn.close();
				} catch (SQLException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}
	}

}

五、创建各实体类

根据数据库表的需要在entity包中新建各实体类，以下为各实体类代码：

Book.java

package cn.egret.entity;

public class Book {
	private int bookId; // 书本ID
	private String bookName; // 书名
	private String bookAuthor; // 作者
	private int bookNum; // 书本剩余量
	private int bookCategory; // 书本类别
	private int bookState; // 书本状态  0表示可借阅  1表示不可借阅
	
	public Book() {
		// TODO Auto-generated constructor stub
	}
	
	public Book(int bookId, String bookName, String bookAuthor, int bookNum, int bookCategory, int bookState) {
		super();
		this.bookId = bookId;
		this.bookName = bookName;
		this.bookAuthor = bookAuthor;
		this.bookNum = bookNum;
		this.bookCategory = bookCategory;
		this.bookState = bookState;
	}

	public int getBookId() {
		return bookId;
	}

	public void setBookId(int bookId) {
		this.bookId = bookId;
	}

	public String getBookName() {
		return bookName;
	}

	public void setBookName(String bookName) {
		this.bookName = bookName;
	}

	public String getBookAuthor() {
		return bookAuthor;
	}

	public void setBookAuthor(String bookAuthor) {
		this.bookAuthor = bookAuthor;
	}

	public int getBookNum() {
		return bookNum;
	}

	public void setBookNum(int bookNum) {
		this.bookNum = bookNum;
	}

	public int getBookCategory() {
		return bookCategory;
	}

	public void setBookCategory(int bookCategory) {
		this.bookCategory = bookCategory;
	}

	public int getBookState() {
		return bookState;
	}

	public void setBookState(int bookState) {
		this.bookState = bookState;
	}

	@Override
	public String toString() {
		return "Book [bookId=" + bookId + ", bookName=" + bookName + ", bookAuthor=" + bookAuthor + ", bookNum="
				+ bookNum + ", bookCategory=" + bookCategory + ", bookState=" + bookState + "]";
	}
	
}

	}
	
	
}

BorrowingInfo.java

package cn.egret.entity;

import java.sql.Timestamp;

public class BorrowingInfo {
	private int borrowingInfoId; // 借阅记录ID

		addressLabel.setBounds(440, 279, 213, 46);
		add(addressLabel);
		
		JLabel userStateLabel = new JLabel(userState);
		userStateLabel.setFont(new Font("宋体", Font.PLAIN, 25));
		userStateLabel.setBounds(142, 393, 200, 37);
		add(userStateLabel);
		
		JLabel userRoleLabel = new JLabel(userRole);
		userRoleLabel.setFont(new Font("宋体", Font.PLAIN, 25));
		userRoleLabel.setBounds(440, 393, 241, 37);
		add(userRoleLabel);
		
		JLabel genderLabel = new JLabel(gender);
		genderLabel.setFont(new Font("宋体", Font.PLAIN, 25));
		genderLabel.setBounds(440, 178, 213, 37);
		add(genderLabel);
	}
}

十、Test包内测试类的创建

package cn.egret.test;

import java.util.ArrayList;
import java.util.List;

import cn.egret.controller.page.smallPage.admin.WelcomePage;
import cn.egret.dao.impl.BookCategoryDaoImpl;
import cn.egret.dao.impl.BookDaoImpl;
import cn.egret.dao.impl.BorrowInfoDaoImpl;
import cn.egret.dao.impl.UserDaoImpl;
import cn.egret.entity.Book;
import cn.egret.entity.BorrowingInfo;
import cn.egret.entity.User;

public class Test {
	public static void main(String[] args) {
		User user = new User("小王","121212",18,"man","110","sky",0,1);
		UserDaoImpl u = new UserDaoImpl();
//		u.addUser(user);
//		System.out.println(user.getUserId());
		
//		User user2 = u.findUserByNameAndPassword("张三", "123456");
//		System.out.println(user2);
		
//		System.out.println(u.findPasswordById(3));
		
//		System.out.println(u.updatePasswordById(1, "555555"));
		
//		User user3 = u.findUserById(2);
//		System.out.println(user3);
		
//		System.out.println(u.updateUserStateById(2, 1));
		
//		System.out.println(u.deleteUserByIdAndUsername(1, "张三"));
//		
//		List<User> l = u.findUser(1);
//		for(User use: l) {
//			System.out.println(use);
//		}
		
//		System.out.println(u.getUserIdByName("张三"));
		
		Book book = new Book(2001,"一书一世界","张晓波",3,2,0);
		BookDaoImpl b = new BookDaoImpl();
//		b.addBook(book);
		
//		b.deleteBook(2001, "一书一世界");
		
//		List<Book> listBook = b.findBookList();
//		for(Book bo: listBook) {
//			System.out.println(bo);
//		}
//		
		
//		Book book2 = b.findBook(2, "操作系统");
//		System.out.println(book2);
		
//		b.changeBookState(1, "操作系统", 0);
		
//		b.borrowBook(1, "操作系统");
		
//		b.giveBackBook(1, "操作系统");
		
		BorrowInfoDaoImpl bor = new BorrowInfoDaoImpl();
//		bor.borrowBook(2, 1);
		
//		bor.giveBackBook(2, 1);
		
//		List<BorrowingInfo> BIList = bor.findBorrowInfo(2);
//		
//		for(BorrowingInfo bbb: BIList) {
//			System.out.println(bbb);
//		}
//		
		
		BookCategoryDaoImpl bci = new BookCategoryDaoImpl();
//		System.out.println(bci.findBookCategoryById(4));
        
//		new WelcomePage();	
	}
}
