通常，是的。
我要做的是在您的
doInBackground方法中用于
SwingUtilities.invokeLater显示对话框，并在您的
done方法中隐藏对话框。
这应该意味着，即使对话框没有出现在屏幕上，您也可以对流程进行更多的控制…
较小的问题是，您现在必须将对话框传递给工作程序，以便它可以控制它。
public class TestSwingWorkerDialog { public static void main(String[] args) { new TestSwingWorkerDialog(); } private JDialog dialog; public TestSwingWorkerDialog() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException ex) { } catch (InstantiationException ex) { } catch (IllegalAccessException ex) { } catch (UnsupportedLookAndFeelException ex) { } MyWorker worker = new MyWorker(); worker.execute(); } }); } public class MyWorker extends SwingWorker<Object, Object> { @Override protected Object doInBackground() throws Exception { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { getDialog().setVisible(true); } }); Thread.sleep(2000); return null; } @Override protected void done() { System.out.println("now in done..."); JDialog dialog = getDialog(); // Don't care, dismiss the dialog dialog.setVisible(false); } } protected JDialog getDialog() { if (dialog == null) { dialog = new JDialog(); dialog.setModal(true); dialog.setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE); dialog.setLayout(new BorderLayout()); dialog.add(new JLabel("Please wait...")); dialog.setSize(200, 200); dialog.setLocationRelativeTo(null); } return dialog; }}
