调整带有图片JPanel的Java JFrame的大小时性能不佳

我设法创建了一个以特殊图片为背景的JPanel，并将这个JPanel放在JFrame中。 每次调整JFrame的大小时，JPanel和其中的图片也会随之调整大小。ComponentListener注册到JFrame，JFrame会通知对其大小的修改

代码如下：

package examples;

import images.MyImage;

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;

import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class example3 {

    private static JPanel panel = new MyPanel();
    private static JFrame frame = new JFrame();

    private static class MyPanel extends JPanel {

        private static final long serialVersionUID = 1L;
        private int width = 0;
        private int height = 0;
        public static final int DEFAULT_WIDTH = 400;
        public static final int DEFAULT_HEIGHT = 100;

        public MyPanel(int width, int heigth) {
            super.setLayout(new BorderLayout());
            setWidth(width);
            setHeigth(heigth);
        }

        public MyPanel() {
            super.setLayout(new BorderLayout());
            setWidth(DEFAULT_WIDTH);
            setHeigth(DEFAULT_HEIGHT);
        }

        @Override
        protected void paintComponent(Graphics g) {
            super.paintComponent(g);
            Graphics2D g2d = (Graphics2D) g;
            g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
                    RenderingHints.VALUE_INTERPOLATION_BILINEAR);
            g2d.setRenderingHint(RenderingHints.KEY_RENDERING,
                    RenderingHints.VALUE_RENDER_SPEED);
            g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                    RenderingHints.VALUE_ANTIALIAS_ON);
            g2d.drawImage(MyImage.IMAGE_BLUE_BLACKGROUND, 0, 0,
                    getMyPanelWidth(), getMyPanelHeight(), null);

            g2d.dispose();
        }

        @Override
        public Dimension preferredSize() {
            return new Dimension(getMyPanelWidth(), getMyPanelHeight());
        }

        private void setWidth(int width) {
            this.width = width;
        }

        private void setHeigth(int height) {
            this.height = height;
        }

        private int getMyPanelHeight() {
            return height;
        }

        private int getMyPanelWidth() {
            return width;
        }

    }

    private static class ComponentHandler extends ComponentAdapter{

        @Override
        public void componentResized(ComponentEvent e) {
            super.componentResized(e);
            frame.remove(panel);
            frame.getContentPane().add(
                    new MyPanel(frame.getSize().width, frame.getSize().height),
                    BorderLayout.CENTER);

            frame.repaint();
            frame.revalidate();

        }

    }

    public static void main(String[] args) {

        panel.setBorder(BorderFactory.createLineBorder(Color.BLACK));

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLayout(new BorderLayout());

        frame.add(panel);
        frame.addComponentListener(new ComponentHandler());

        frame.pack();
        frame.setVisible(true);
    }

}

问题是我遇到了缩放错误：

是因为事件分派线程无法处理resize方法触发的所有resize事件吗？有什么令人满意的解决方案吗？

一般来说，不要在“绘制方法”中调整图像大小。您可以尝试类似的方法，这样可以将图像更改整合为尽可能少的更新，并生成低质量（快速缩放）和高质量（慢速缩放）的结果。。。
