在Java Swing中,如何获得对窗口的Win32窗口句柄(hwnd)引用？

import java.awt.Component;
import java.awt.Window;
import java.lang.reflect.Field;
import javax.swing.JFrame;

public class HwndExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Hwnd Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 300);
        frame.setVisible(true);

        long hwnd = getHwnd(frame);
        System.out.println("HWND: " + hwnd);
    }

    public static long getHwnd(Component component) {
        try {
            Field field = Class.forName("java.awt.Window").getDeclaredField("hwnd");
            field.setAccessible(true);
            return field.getLong(component);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return 0;
    }
}
