如何将已编辑的JTable单元格记录更新到数据库中

import java.sql.*;

public class JTableToDatabase {
    public static void main(String[] args) {
        // 获取JTable中已编辑的单元格数据
        // 这里假设JTable的TableModel为tableModel
        // 遍历tableModel，获取已编辑的单元格数据
        // ...

        // 建立数据库连接
        Connection connection = null;
        try {
            Class.forName("com.mysql.jdbc.Driver");
            String url = "jdbc:mysql://localhost:3306/mydatabase";
            String username = "root";
            String password = "password";
            connection = DriverManager.getConnection(url, username, password);

            // 构建SQL更新语句
            String sql = "UPDATE mytable SET column1 = ?, column2 = ? WHERE id = ?";

            // 执行SQL更新语句
            PreparedStatement statement = connection.prepareStatement(sql);
            // 假设需要更新的数据为data1, data2, id
            statement.setString(1, data1);
            statement.setString(2, data2);
            statement.setInt(3, id);
            statement.executeUpdate();

            // 关闭Statement
            statement.close();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭数据库连接
            if (connection != null) {
                try {
                    connection.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
