如何在Java中使用无限循环中断线程并进行睡眠

Question

我已经为此战斗了几个小时。 这是代码：

@Override
public void run()
{
    try
    {
        wscript.setBid(0.30);

        wscript.setServiceMode(WebScript.ServiceMode.ON);

        for(;!Thread.currentThread().isInterrupted();)
        {               
            Positioning(demandedPosition, maximumBid);
            if(Thread.currentThread().isInterrupted())
                break;
            Thread.sleep(10000);
        }
        wscript.setServiceMode(ServiceMode.OFF);
        Log("Algorithm has been canceled!");
    } 
    catch (InterruptedException e)
    {
        wscript.setServiceMode(ServiceMode.OFF);
        Log("Algorithm has been canceled!");
        return;
    }

事情是，我想用这段代码合法地打断它：

private void StopService()
{
    service.interrupt();
}

当我在Thread.sleep（）运行时调用此方法时，它将获取InterruptedException并且一切正常。 但是，正如我所说的，当PositioningAlgorithm运行时，什么也没有发生，线程的行为就像它从未处于中断状态一样。 问候，双核

编辑：对我来说，至关重要的是调用Log（“ Algorithm has been cancelled！”）; 将在中断后执行。

已解决：我已经覆盖Thread.interrupt()来编辑类本地变量，该类已检查线程是否已准备好结束：

service = new Thread(mechanism)
            {
                @Override
                public void interrupt()
                {
                    super.interrupt();
                    mechanism.ReadyToReturn = true;
                }
            };

这是更新的线程主算法：

@Override
public void run()
{
    try
    {
        wscript.setBid(0.30);
        wscript.setServiceMode(WebScript.ServiceMode.ON);
        for(;!ReadyToReturn || !Thread.currentThread().isInterrupted();)
        {               
            Positioning(demandedPosition, maximumBid);
            if(ReadyToReturn || Thread.currentThread().isInterrupted())
                break;
            Thread.sleep(10000);
        }
        wscript.setServiceMode(ServiceMode.OFF);
        Log("Algorithm has been canceled!");

    } 
    catch (InterruptedException e)
    {
        wscript.setServiceMode(ServiceMode.OFF);
        Log("Algorithm has been canceled!");
        return;
    }

}

Answer 1

发生这种情况的原因是，定位清除了isInterrupted标志（请参阅https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#interrupted%28%29 ）和/或在某个地方捕获InterruptedException （或Exception / Throwable ）。

一种可能性是使用另一个标志（例如，使用volatile变量/ AtomicBoolean / ThreadLocal ）来指示是否应中断线程。
