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 BufferedImageinstance as an argument.
如果您只想使用圆形按钮的图像，那么为什么不使用JLabel？也就是说，只需调用setIcon(...)，将您的BufferedImage实例作为参数传递。
CODE
代码
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
输出
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.
请记住，您需要以编程方式使图像的背景透明，或者需要使用像Paint.NET这样的图像编辑工具。

You can use JavaFX to define "Rich Graphic Components" example (rounded button with gradient): http://poligloci.blogspot.com/2009/07/beauty-and-beast-javafx-12-in-netbeans.html
您可以使用 JavaFX 来定义“丰富的图形组件”示例（带渐变的圆形按钮）：http: //poligloci.blogspot.com/2009/07/beauty-and-beast-javafx-12-in-netbeans.html
