对我来说很好……

除了你没有处理异常(可能对诊断有用)并且没有真正在EDT中加载程序的事实,它似乎工作得很好……

public class TestURLImage {

public static void main(String[] args) {

new TestURLImage();

}

public TestURLImage() {

EventQueue.invokeLater(new Runnable() {

@Override

public void run() {

try {

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {

}

try {

String path = "http://chart.finance.yahoo.com/z?s=GOOG&t=6m&q=l";

System.out.println("Get Image from " + path);

URL url = new URL(path);

BufferedImage image = ImageIO.read(url);

System.out.println("Load image into frame...");

JLabel label = new JLabel(new ImageIcon(image));

JFrame f = new JFrame();

f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

f.getContentPane().add(label);

f.pack();

f.setLocation(200, 200);

f.setVisible(true);

} catch (Exception exp) {

exp.printStackTrace();

}

}

});

}

}
