我在Netbeans工作（不确定是否是一个因素）。

我只是想在后台运行一个简单的SwingWorker。我调用“ doInBackground（）”，但调用线程仍处于暂停状态，直到工作人员完成为止。

即使是陌生人，当我从后台工作内部调用Thread.currentThread时，它也告诉我我正在处理事件调度线程（后台工作人员正在前台工作？）。

private void startButtonmouseReleased(java.awt.event.MouseEvent evt) {                                          
    if(startButton.isEnabled()) {
        StartingWorker worker = new StartingWorker();
        worker.doInBackground();
    }
}     

private class StartingWorker extends SwingWorker<Void,Void> {
    public StartingWorker() {
    }

    @Override
    public Void doInBackground() {
        startOperation();
        return null;
    }

    @Override
    protected void done() {

    }
}

private void startOperation() {
    //When I call currentThread(),it says that this is the Even Dispatch Thread
    //even though this message is being called from a SwingWorker.
    Thread thread = Thread.currentThread();
    try {
        session.populate(reporter);
        Runnable run = new Runnable() {
            public void run() {
                callObservers(true);
            }
        };
        SwingUtilities.invokeAndWait(run);
    }
    catch(Exception e) {
        unlock();
        Dialogs.showErrorDialog(this.getParent());
    }
}
