如何在Java中使用無限循環中斷線程並進行睡眠

Question

我已經為此戰斗了幾個小時。 這是代碼：

@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，我想用這段代碼合法地打斷它：

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

當我在Thread.sleep（）運行時調用此方法時，它將獲取InterruptedException並且一切正常。 但是，正如我所說的，當PositioningAlgorithm運行時，什么也沒有發生，線程的行為就像它從未處於中斷狀態一樣。 問候，雙核

編輯：對我來說，至關重要的是調用Log（“ Algorithm has been cancelled！”）; 將在中斷后執行。

已解決：我已經覆蓋Thread.interrupt()來編輯類本地變量，該類已檢查線程是否已准備好結束：

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

這是更新的線程主算法：

@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;
    }

}

發生這種情況的原因是，定位清除了isInterrupted標志（請參閱https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#interrupted%28%29 ）和/或在某個地方捕獲InterruptedException （或Exception / Throwable ）。

一種可能性是使用另一個標志（例如，使用volatile變量/ AtomicBoolean / ThreadLocal ）來指示是否應中斷線程。
