用java的swing元件實現簡易的圖書管理系統
阿新 • • 發佈：2019-02-12
圖書管理系統在生活和學校中是最為常見的，這學期的java課程設計題目中的其中一個就是實現圖書管理系統，
做完課設後，在此記錄下。
我的圖書管理系統一共分為幾個模組。圖書查詢模組，管理員模組（預設只有一個管理員），讀者模組。
圖書管理系統結構圖如下所示：
1、管理員模組
管理員模組中一共包含三個部分，其一是管理員登入（此係統預設只有一個管理員），其二是圖書入庫管理，其三是使用者借閱資訊管理。
主視窗程式程式碼如下：主要執行查詢操作和顯示查詢結果：
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("圖書查詢"); //窗體最上面的部分 label1 = new JLabel("圖書查詢",SwingConstants.CENTER); label1.setFont(new Font("楷體",Font.BOLD,40)); //設定字型和大小 //窗體中間的部分 label2 = new JLabel("書名:"); text = new JTextField(15); button = new JButton("查詢"); jpanel = new JPanel(); jpanel.setLayout(new BorderLayout()); jp1 = new JPanel(); jp2 = new JPanel(); //窗體最下面的部分（及顯示查詢內容的地方） // jp2.setBackground(Color.BLUE); stu = new JButton("使用者登入"); admin = new JButton("管理員"); // //測試 // lend = new JButton("確認借閱"); 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(){ // 查詢按鈕事件 button.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent arg0) { // TODO Auto-generated method stub new FindBook().findInfo(jp2,text); } }); // 管理員按鈕事件 admin.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent arg0) { // TODO Auto-generated method stub new LoginFrame().show(); } }); //使用者按鈕事件 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(); } }
主視窗顯示效果如下：
管理員登入：預設管理員賬號為admin，若密碼輸入錯誤則有提示資訊，密碼正確則進入管理員管理介面。完整程式碼如下：
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; // 管理員登入模組 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("圖書館管理系統登入"); this.setLayout(new BorderLayout()); label = new JLabel("登入",SwingConstants.CENTER); label.setFont(new Font("楷體",Font.BOLD,30)); name = new JLabel("賬 號"); pass = new JLabel("密 碼"); adminName = new JTextField(12); adminName.setText("admin"); adminName.setHorizontalAlignment(SwingConstants.CENTER); password = new JPasswordField(12); password.setHorizontalAlignment(SwingConstants.CENTER); password.setEchoChar('*'); //設定回顯字元 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("登入"); 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"; // 正確密碼 String str = new String(password.getPassword()); if(str.equals(word)) new LendAdminFrame().show(); // new TableFrame().show(); // new RuKuFrame(); else{ String str1 = "你輸入的密碼不正確，原因可能是：\n" + "1、忘記密碼；\n" + "2、未開啟小鍵盤；\n" + "3、大小寫未區分。"; JOptionPane.showMessageDialog(null, str1); // new LoginErrorFrame().show(); } LoginFrame.this.dispose(); } }); } public static void main(String[] args){ new LoginFrame(); } }
程式碼執行後顯示如下：
密碼錯誤時：
圖書入庫管理：管理員在此介面內對圖書資訊進行管理。包括圖書在館內的圖書號、圖書名、撰寫此書的作者、書的種類（可以是專業分類）、出版社、入庫日期、借閱狀態以及分佈的校區（或分館）。
使用者借閱資訊管理：管理員在此介面可以對使用者的借閱資訊進行管理。包括借閱者賬號（預設為姓名）、所借圖書編號、書名以及借書日期。此表會根據使用者借閱圖書以及歸還圖書動態變化。
圖書入庫管理和使用者借閱資訊管理的功能我用了一個類來實現。不過由另外一個類寫了兩個按鈕，來保證究竟要哪一個功能起作用。用於管理這兩個小模組的程式碼如下：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("管理員"); this.setBounds(400,300,200,200); this.setLayout(new FlowLayout(FlowLayout.CENTER)); storage = new JButton("圖書入庫管理"); lendInfo = new JButton("借閱資訊管理"); this.add(storage); this.add(lendInfo); MyEvent(); this.setVisible(true); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } public void MyEvent(){ // 圖書入庫管理 storage.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent arg0) { // TODO Auto-generated method stub new TableFrame(storage.getText()).show(); } }); // 使用者借閱資訊管理 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(); } }

public static void main(String[] args){

}圖書入庫顯示效果如下所示：

借閱資訊管理顯示如下：
2、圖書查詢模組
圖書查詢分為兩個部分，一個是查詢全部（查詢框無內容時），另一個是按照關鍵字查詢。
查詢全部：查詢框無查詢內容時直接點選查詢按鈕，則會顯示資料庫中所有的圖書資料。
按照關鍵字查詢：查詢框中有關鍵字時，則會顯示與關鍵字相關的圖書資料。
此模組用一個類來實現，需要連線資料庫，由主頁面的查詢按鈕控制程式碼如下：package per.tushu.storage;

3、讀者模組
讀者模組包括四個操作，其一是使用者註冊與登入，其二是查詢自身的借閱資訊，其三是借閱圖書，最後一個是歸還圖書。
使用者註冊與登入：使用者若要借書，則需要先進行註冊，然後登入。註冊成功後則其註冊資訊會寫入資料庫以便以後登入使用。若登陸密碼或賬號錯誤，則會有相應提示資訊。
查詢自身的借閱資訊：若使用者已經註冊並且登入成功，可以通過這一某塊檢視自己的借閱資訊（一般是看是否借閱超期）。可以顯示的內容有借閱的圖書編號、圖書名、借書時間、應還日期、距離應還日期的天數以及借閱狀態（是否超期）。
借閱圖書：在此模組可以根據想要借閱的圖書編號借閱圖書。
歸還圖書：在此模組可以根據想要歸還的圖書編號歸還圖書。
