java-SwingWorker中的thread.sleep() [英] java - thread.sleep() within SwingWorker

问题描述

我只是想知道以下代码是否正确.我有一个SwingWorker，它可以执行某些操作，进行睡眠，执行其他操作并更新GUI.在SwingWorker中使用Thread.sleep可以吗?

I am just wondering if the following code is correct. I have a SwingWorker that does something, sleeps, does something else and updates GUI. Is it okay to use Thread.sleep inside SwingWorker?

class MySwingy extends SwingWorker<Void, Void> {

    @Override
    public Void doInBackground() {

        //Do Something

        try {
            Thread.sleep(200);
        } catch (Exception ex) {
        }

        //Do Something

    }

    @Override
    public void done() {
        //Update GUI
    }
}

推荐答案

如果确实需要，则没有技术原因不能执行此操作.将阻塞的线程是一个后台线程，您的UI不会阻塞.

If you really need to, there is no technical reason why you can't do that. The thread that will block is a background thread and your UI will not block.

但是我想问一下为什么你需要在后台线程中睡觉吗?也许可以改进您的设计以消除这种需求?

But may I ask why you need to sleep in a background thread? Maybe your design can be improved to remove that need?
