这是我在网上找到的，大家看看，我也是个超级菜鸟
import java.awt.Graphics;

import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class TestBackground extends JFrame{
ImageIcon img;

public TestBackground(){
img = new ImageIcon("D:/temp/Winter.jpg");

JPanel panel = new JPanel(){
public void paintComponent(Graphics g){
g.drawImage(img.getImage(), 0, 0, null);
super.paintComponent(g);
}
};

panel.setOpaque(false);
panel.add( new JButton( "Hello" ) );
setContentPane( panel );
}

public static void main(String [] args){
TestBackground frame = new TestBackground();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300, 300);
frame.setVisible(true);
}
}
