解决方案

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.

CODE

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);

}

}

OUTPUT

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.
