图书管理系统java简历怎么介绍 javagui图书管理系统

图书管理系统在生活和学校中是最为常见的，这学期的java课程设计题目中的其中一个就是实现图书管理系统，

做完课设后，在此记录下。

我的图书管理系统一共分为几个模块。图书查询模块，管理员模块（默认只有一个管理员），读者模块。

图书管理系统结构图如下所示：

1、管理员模块

管理员模块中一共包含三个部分，其一是管理员登录（此系统默认只有一个管理员），其二是图书入库管理，其三是用户借阅信息管理。

主窗口程序代码如下：主要执行查询操作和显示查询结果：

package per.tushu.frame;

import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.SwingConstants;
import javax.swing.table.DefaultTableModel;

import per.tushu.storage.FindBook;

public class MainFrame extends JFrame{
	JLabel label1,label2,info;	
	JPanel jpanel,jp1,jp2,jp3;
	JTextField text;
	JButton button,admin,stu;
	
	JButton lend;
	DefaultTableModel tableModel;
	
	public MainFrame(){
		this.setLayout(new BorderLayout());
		this.setBounds(400, 200, 600, 450);
		this.setTitle("图书查询");
	
		//窗体最上面的部分
		label1 = new JLabel("图书查询",SwingConstants.CENTER);
		label1.setFont(new Font("楷体",Font.BOLD,40));		//设置字体和大小
		
		//窗体中间的部分
		label2 = new JLabel("书名:");
		
		text = new JTextField(15);
		button = new JButton("查询");
		
		jpanel = new JPanel();
		jpanel.setLayout(new BorderLayout());
		jp1 = new JPanel();
		jp2 = new JPanel();		//窗体最下面的部分（及显示查询内容的地方）
//		jp2.setBackground(Color.BLUE);
		
		stu = new JButton("用户登录");
		admin = new JButton("管理员");
		
//		//测试
//		lend = new JButton("确认借阅");
		
		
		jp1.add(label2);
		jp1.add(text);
		jp1.add(button);
//		jp1.add(lend);
				
		jp3 = new JPanel();
		jp2.setLayout(new BorderLayout());
		jp3.setLayout(new FlowLayout(FlowLayout.RIGHT));
		jp3.add(stu);
		jp3.add(admin);
		jp2.add(jp3,BorderLayout.SOUTH);
		
		
		
//		jp2.add(info,BorderLayout.SOUTH);
		
		jpanel.add(jp1,BorderLayout.NORTH);
		jpanel.add(jp2);
		
		
		
		this.add(label1,BorderLayout.NORTH);
		this.add(jpanel);
		
		MyEvent();
		
		this.setVisible(true);
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		
	}

	public void MyEvent(){
		// 查询按钮事件
		button.addActionListener(new ActionListener(){

			@Override
			public void actionPerformed(ActionEvent arg0) {
				// TODO Auto-generated method stub
				new FindBook().findInfo(jp2,text);
			}
			
		});
		
		// 管理员按钮事件
		admin.addActionListener(new ActionListener(){

			@Override
			public void actionPerformed(ActionEvent arg0) {
				// TODO Auto-generated method stub
				new LoginFrame().show();
			}
			
		});
		
		//用户按钮事件
		stu.addActionListener(new ActionListener(){

			@Override
			public void actionPerformed(ActionEvent arg0) {
				// TODO Auto-generated method stub
				new UserLoginFrame().show();
			}
			
		});
	}
	
	public static void main(String[] args){
		new MainFrame();
	}
}

主窗口显示效果如下：

管理员登录：默认管理员账号为admin，若密码输入错误则有提示信息，密码正确则进入管理员管理界面。完整代码如下：

package per.tushu.frame;

import java.awt.BorderLayout;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JPasswordField;
import javax.swing.JTextField;
import javax.swing.SwingConstants;

// 管理员登录模块
public class LoginFrame extends JFrame{
	JLabel label,name,pass;
	JButton login;
	JTextField adminName;
	JPasswordField password;
	JPanel panel,jp1,jp2;
	
	public LoginFrame(){
		this.setBounds(400, 200, 300, 200);
		this.setTitle("图书馆管理系统登录");
		this.setLayout(new BorderLayout());
		
		label = new JLabel("登录",SwingConstants.CENTER);
		label.setFont(new Font("楷体",Font.BOLD,30));
		
		name = new JLabel("账 号");
		pass = new JLabel("密 码");
		
		adminName = new JTextField(12);
		adminName.setText("admin");
		adminName.setHorizontalAlignment(SwingConstants.CENTER);
		password = new JPasswordField(12);
		password.setHorizontalAlignment(SwingConstants.CENTER);
		password.setEchoChar('*');		//设置回显字符
		
		panel = new JPanel();
		jp1 = new JPanel();
		jp2 = new JPanel();
		panel.setLayout(new BorderLayout());
		
		jp1.add(adminName);
		jp1.add(name);
		jp1.add(password);
		jp1.add(pass);
		
		panel.add(jp1);
		
		login = new JButton("登录");
		jp2.add(login);
		panel.add(jp2,BorderLayout.SOUTH);
		
		this.add(label,BorderLayout.NORTH);
		this.add(panel);
		
		MyEvent();
		
		this.setVisible(true);
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
	
	public void MyEvent(){
		login.addActionListener(new ActionListener(){

			@Override
			public void actionPerformed(ActionEvent e) {
				// TODO Auto-generated method stub
				String word = "123456";	// 正确密码
				String str = new String(password.getPassword());
				
				if(str.equals(word))
					new LendAdminFrame().show();
//					new TableFrame().show();
//					new RuKuFrame();
				else{
					String str1 = "你输入的密码不正确，原因可能是：\n" +  "1、忘记密码；\n" + "2、未开启小键盘；\n" + "3、大小写未区分。";
					JOptionPane.showMessageDialog(null, str1);
//					new LoginErrorFrame().show();
					
				}
				LoginFrame.this.dispose();
			}

		});
	}
	
	public static void main(String[] args){
		new LoginFrame();
	}
}

代码执行后显示如下：

密码错误时：

图书入库管理：管理员在此界面内对图书信息进行管理。包括图书在馆内的图书号、图书名、撰写此书的作者、书的种类（可以是专业分类）、出版社、入库日期、借阅状态以及分布的校区（或分馆）。

用户借阅信息管理：管理员在此界面可以对用户的借阅信息进行管理。包括借阅者账号（默认为姓名）、所借图书编号、书名以及借书日期。此表会根据用户借阅图书以及归还图书动态变化。

图书入库管理和用户借阅信息管理的功能我用了一个类来实现。不过由另外一个类写了两个按钮，来保证究竟要哪一个功能起作用。用于管理这两个小模块的代码如下：

package per.tushu.frame;

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class LendAdminFrame extends JFrame{
	JPanel panel;
	JButton storage,lendInfo;
	public LendAdminFrame(){
		this.setTitle("管理员");
		this.setBounds(400,300,200,200);
		this.setLayout(new FlowLayout(FlowLayout.CENTER));
		
		storage = new JButton("图书入库管理");
		lendInfo = new JButton("借阅信息管理");
		
		this.add(storage);
		this.add(lendInfo);
		
		MyEvent();
		
		this.setVisible(true);
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
	
	public void MyEvent(){
		// 图书入库管理
		storage.addActionListener(new ActionListener(){

			@Override
			public void actionPerformed(ActionEvent arg0) {
				// TODO Auto-generated method stub
				new TableFrame(storage.getText()).show();
			}
			
		});
		
		// 用户借阅信息管理
		lendInfo.addActionListener(new ActionListener(){

			@Override
			public void actionPerformed(ActionEvent arg0) {
				// TODO Auto-generated method stub
				new TableFrame(lendInfo.getText()).show();
			}
			
		});
	}
	
	public static void main(String[] args){
		new LendAdminFrame();
	}
}

代码显示效果如下：

借阅信息管理显示如下：

2、图书查询模块

图书查询分为两个部分，一个是查询全部（查询框无内容时），另一个是按照关键字查询。

查询全部：查询框无查询内容时直接点击查询按钮，则会显示数据库中所有的图书数据。

按照关键字查询：查询框中有关键字时，则会显示与关键字相关的图书数据。

此模块用一个类来实现，需要连接数据库，由主页面的查询按钮控制代码如下：

package per.tushu.storage;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.Vector;

import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTextField;
import javax.swing.table.DefaultTableModel;

public class FindBook {
	
	Vector tableName;
	
	// 拿到数据库中所有表的名字并储存到集合中
	private Vector getTableName(){
		tableName = new Vector();
		
		Connection conn;
		PreparedStatement preparedStatement;
		try {
			Class.forName("com.mysql.jdbc.Driver");
			conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/bookstorage","root","123456");
//			if(!conn.isClosed())
//				System.out.println("成功打开数据库");
			
			String sql = "show tables";
			preparedStatement = conn.prepareStatement(sql);
			ResultSet result = preparedStatement.executeQuery();
			ResultSetMetaData metaData = result.getMetaData();
						
			while(result.next()){
				for(int i = 1; i <= metaData.getColumnCount(); i++){
					tableName.addElement(result.getString(i));
				}
			}
			
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			System.out.println("未成功加载驱动");
			e.printStackTrace();
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			System.out.println("未成功打开数据库");
			e.printStackTrace();
		}
		return tableName;
	}
	
	
	// 构造函数
	public FindBook(){}
	
	// 拿到要查询的信息并输出到主界面
	public void findInfo(JPanel panel,JTextField text){
				
/*		for(int i = 0; i < names.size(); i++)
			System.out.println(names.get(i));*/
				
		ArrayList<ArrayList<String>> datas = new ArrayList<ArrayList<String>>();	// 数据库中所有的图书信息
		ArrayList<ArrayList<String>> outputDatas = new ArrayList<ArrayList<String>>();		// 记录需要输出的信息（中间量）
		ArrayList<ArrayList<String>> bookN = new ArrayList<ArrayList<String>>();	// 所有可借书籍的信息（在记录可借书的ID号时用到，属中间量）
		ArrayList<ArrayList<String>> outputBook = new ArrayList<ArrayList<String>>();		//记录所有可借书籍的ID号
		
		ArrayList<String> lendBooks = new ArrayList<String>();	//存储所有书籍的名称
		
//		Vector headers = null;
		Connection conn;
		PreparedStatement preparedStatement = null;

3、读者模块

读者模块包括四个操作，其一是用户注册与登录，其二是查询自身的借阅信息，其三是借阅图书，最后一个是归还图书。

用户注册与登录：用户若要借书，则需要先进行注册，然后登录。注册成功后则其注册信息会写入数据库以便以后登录使用。若登陆密码或账号错误，则会有相应提示信息。

查询自身的借阅信息：若用户已经注册并且登录成功，可以通过这一某块查看自己的借阅信息（一般是看是否借阅超期）。可以显示的内容有借阅的图书编号、图书名、借书时间、应还日期、距离应还日期的天数以及借阅状态（是否超期）。

借阅图书：在此模块可以根据想要借阅的图书编号借阅图书。

归还图书：在此模块可以根据想要归还的图书编号归还图书。

这个系统没有用到windbuilder等可视化工具，也没有进行页面美化的操作，因此执行结果相对来说不太好看，仅是实现了基本功能，而且其中的极个别按键没有赋予功能，还需改善。完整工程我会上传到博客中的资源区，需要的可以下载。
