我想在JButton中将数据库值动态显示为测试

import javax.swing.JButton;
import javax.swing.JFrame;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class DatabaseButtonExample {
    public static void main(String[] args) {
        // 连接到数据库
        Connection connection = null;
        try {
            connection = DriverManager.getConnection("jdbc:mysql://your_database_url", "username", "password");
        } catch (SQLException e) {
            e.printStackTrace();
        }

        // 创建JFrame和JButton
        JFrame frame = new JFrame("Database Button Example");
        JButton button = new JButton();

        // 获取数据库值并设置为按钮文本
        try {
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery("SELECT test_value FROM your_table");
            if (resultSet.next()) {
                String value = resultSet.getString("test_value");
                button.setText(value);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }

        // 将按钮添加到JFrame并显示
        frame.getContentPane().add(button);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}
