JAVA图书管理系统MySQL创建GUI代码

以下是一个简单的JAVA图书管理系统的MySQL创建GUI代码示例：

import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JTextField;

public class CreateGUI {

    private JFrame frame;
    private JTextField bookNameTextField;
    private JTextField authorTextField;
    private JTextField publisherTextField;

    private final String url = "jdbc:mysql://localhost:3306/library";
    private final String user = "root";
    private final String password = "root";

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                try {
                    CreateGUI window = new CreateGUI();
                    window.frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        });
    }

    public CreateGUI() {
        initialize();
    }

    private void initialize() {
        frame = new JFrame();
        frame.setBounds(100, 100, 450, 300);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().setLayout(null);

        JLabel lblNewLabel = new JLabel("图书名称：");
        lblNewLabel.setBounds(50, 50, 100, 30);
        frame.getContentPane().add(lblNewLabel);

        bookNameTextField = new JTextField();
        bookNameTextField.setBounds(150, 50, 200, 30);
        frame.getContentPane().add(bookNameTextField);
        bookNameTextField.setColumns(10);

        JLabel lblNewLabel_1 = new JLabel("作者：");
        lblNewLabel_1.setBounds(50, 100, 100, 30);
        frame.getContentPane().add(lblNewLabel_1);

        authorTextField = new JTextField();
        authorTextField.setBounds(150, 100, 200, 30);
        frame.getContentPane().add(authorTextField);
        authorTextField.setColumns(10);

        JLabel lblNewLabel_2 = new JLabel("出版社：");
        lblNewLabel_2.setBounds(50, 150, 100, 30);
        frame.getContentPane().add(lblNewLabel_2);

        publisherTextField = new JTextField();
        publisherTextField.setBounds(150, 150, 200, 30);
        frame.getContentPane().add(publisherTextField);
        publisherTextField.setColumns(10);

        JButton btnNewButton = new JButton("添加");
        btnNewButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                String bookName = bookNameTextField.getText();
                String author = authorTextField.getText();
                String publisher = publisherTextField.getText();
                Connection conn = null;
                PreparedStatement pstmt = null;
                try {
                    Class.forName("com.mysql.jdbc.Driver");
                    conn = DriverManager.getConnection(url, user, password);
                    String sql = "INSERT INTO book (book_name, author, publisher) VALUES (?, ?, ?)";
                    pstmt = conn.prepareStatement(sql);
                    pstmt.setString(1, bookName);
                    pstmt.setString(2, author);
                    pstmt.setString(3, publisher);
                    pstmt.executeUpdate();
                    JOptionPane.showMessageDialog(null, "添加成功");
                } catch (Exception ex) {
                    ex.printStackTrace();
                    JOptionPane.showMessageDialog(null, "添加失败");
                } finally {
                    try {
                        if (pstmt != null) {
                            pstmt.close();
                        }
                        if (conn != null) {
                            conn.close();
                        }
                    } catch (Exception ex) {
                        ex.printStackTrace();
                    }
                }
            }
        });
        btnNewButton.setBounds(150, 200, 100, 30);
        frame.getContentPane().add(btnNewButton);
    }
}

上述代码创建了一个简单的图书管理系统的添加图书的GUI界面，并且将数据保存到MySQL数据库中。你需要根据实际需求修改数据库的连接信息和SQL语句。同时，你还需要在代码中添加其他的功能，如删除图书、修改图书信息等。
