在MacOS下，尝试使用类似Application＃requestUserAttention（boolean）
import com.apple.eawt.Application;...Application application = Application.getApplication();application.requestUserAttention(false);
nb-我还没有尝试过-抱歉。
更新了示例
从JavaDocs
要求用户注意此应用程序（通常通过弹跳Dock图标）。关键请求将继续跳出Dock图标，直到激活该应用程序为止。已经活动的请求关注的应用程序什么也不做。
这意味着，如果应用程序具有焦点，则该方法将不执行任何操作。
在Mac OSX 10.7.5，Java 1.7.0_07上测试
import com.apple.eawt.Application;import java.awt.BorderLayout;import java.awt.Dimension;import java.awt.EventQueue;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;import java.io.IOException;import javax.imageio.ImageIO;import javax.swing.Jframe;import javax.swing.JPanel;import javax.swing.SwingUtilities;import javax.swing.Timer;import javax.swing.UIManager;import javax.swing.UnsupportedLookAndFeelException;public class TestMacIcon { public static void main(String[] args) { new TestMacIcon(); } public TestMacIcon() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) { } Jframe frame = new Jframe("Test"); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.setLayout(new BorderLayout()); frame.add(new TestPane()); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); } public class TestPane extends JPanel { public TestPane() { final Application application = Application.getApplication(); addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { try { System.out.println("clicked"); application.requestUserAttention(true); application.setDockIconImage(ImageIO.read(getClass().getResource("/Java.png"))); application.setDockIconBadge("Blah"); application.requestUserAttention(true); } catch (IOException ex) { ex.printStackTrace(); } } }); Timer time = new Timer(2000, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { if (!SwingUtilities.getWindowAncestor(TestPane.this).hasFocus()) { ((Timer)e.getSource()).stop(); System.out.println("Pay attention!!"); application.requestUserAttention(true); } } }); time.setRepeats(true); time.setCoalesce(true); time.start(); } @Override public Dimension getPreferredSize() { return new Dimension(200, 200); } }}PS确保您专注于应用程序;）
