推荐答案

如果您只想使用圆形按钮的图像，那为什么不只使用JLabel呢?也就是说，只需调用

If you're just going to use an image of a round button, then why not just use a JLabel? That is, simply invoke setIcon(...), passing your BufferedImage instance as an argument.

public final class RoundedButtonDemo {
    private static BufferedImage bi;

    public static void main(String[] args){
        try {
            loadImage();

            SwingUtilities.invokeLater(new Runnable(){
                @Override
                public void run() {
                    createAndShowGUI();             
                }
            });
        } catch (IOException e) {
            // handle exception
        }
    }

    private static void loadImage() throws IOException{
        bi = ImageIO.read(RoundedButtonDemo.class.getResource("../resources/login.png"));
    }

    private static void createAndShowGUI(){
        final JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        final JLabel label = new JLabel();
        label.setIcon(new ImageIcon(bi));

        frame.getContentPane().add(label);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }
}

输出

请记住，您需要以编程方式使图像的背景透明，或者需要使用图像编辑工具，例如

Keep in mind that you'll need to either programmatically make the background of your image transparent, or you'll need to use an image editing tool like Paint.NET.
