JAVA中paintComponents（）怎么实现加载图片，我下面代码为什么没效果啊

[qq_25664871]

@Override
public void paintComponents(java.awt.Graphics g) {
Image image=new ImageIcon("123.gif").getImage();
g.drawImage(image, 0, 0,this.WIDTH,this.HEIGHT, this);
};

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;

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


public class MyPaint extends JFrame {
	
	private class MyPanel extends JPanel{
		
		public void paintComponent(Graphics g) {
			// TODO Auto-generated method stub
			Image image = new ImageIcon("123.gif").getImage();
			g.drawImage(image,0,0,100,100,this);
			super.paintComponents(g);
			
		}
		
	}

	public void service(){
		
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		MyPanel panel = new MyPanel();
		
		add(panel);
		setPreferredSize(new Dimension(300,200));
		pack();
		setLocationRelativeTo(null);
		setVisible(true);
		
	}
	
	public static void main(String[] args) {
		
		MyPaint demo = new MyPaint();
		demo.service();
		
	}
	
}

使用paintComponent 覆盖 而不是 paintComponents
