正如其他人所建议的，最好的方法是使用
SwingWorker。
SwingWorker属性是可监听的，并且总是在EDT中调用监听器，因此，您可以执行以下操作：
public class ArchivingWorker extends SwingWorker<Void, Void> { JProgressBar progressBar = null; // Other members here... ... public ArchivingWorker(...) { // Any specific initialization here (in EDT) addPropertyChangeListener(new PropertyChangeListener() { @Override void propertyChange(PropertyChangeEvent e) { if ( "state".equals(e.getPropertyName()) && e.getNewValue() == Statevalue.STARTED) { // Background thread has just started, show a progress dialog here progressBar = new JProgressBar(); ... } else if ("progress".equals(e.getPropertyName())) { // Update progress bar here with e.getNewValue() ... } } }); } @Override protected Void doInBackground() { // Archiving process here and update progress from time to time setProgress(progress); return null; } @Override protected void done() { // Ensure that archiving process worked correctly (no exception) try { get(); } catch (Exception e) { // Handle exception (user feedback or whatever) } finally { // Close progress dialog ... } }}然后，您可以
ArchivingWorker根据需要使用：
ArchivngWorker worker = new ArchivingWorker(...);worker.execute();
