我有一个带有IOBound任务的SwingWorker线程,它在运行时完全锁定了界面.更换计数器循环的正常工作负载具有相同的结果.SwingWorker看起来基本上是这样的:

public class BackupWorker extends SwingWorker<String, String> {

private static String uname = null;
private static String pass = null;
private static String filename = null;
static String status = null;

BackupWorker (String uname, String pass, String filename) {
    this.uname = uname;
    this.pass = pass;
    this.filename = filename;
}

@Override
protected String doInBackground() throws Exception {
            BackupObject bak = newBackupObject(uname,pass,filename);
    return "Done!";
}

}

启动它的代码存在于扩展JFrame的类中:

    public void actionPerformed(ActionEvent event) {
    String cmd = event.getActionCommand();

    if (BACKUP.equals(cmd)) { 
        SwingUtilities.invokeLater(new Runnable() { …
