部分问题在于我不知道清除中断标志的每个方法调用。
重要的是要澄清以下方法通过调用它们来清除中断标志:
Thread.interrupted()
Thread.isInterrupted(true) -- added to your list
因此,应始终使用。Thread.currentThread().isInterrupted()
以下方法将通过立即抛出中断标志来清除中断标志,如果它们被调用,然后线程被中断,或者如果线程已经中断,然后它们被调用(请参阅下面的 junit 代码)。因此,清除标志的方法不是,而是引发异常。InterruptedException
您的初始列表:
Thread.interrupted()
Thread.sleep(long)
Thread.join()
Thread.join(long)
Object.wait()
Object.wait(long)
已添加到您的列表中:
Thread.sleep(long, int)
Thread.join(int, long)
Thread.isInterrupted(true)
Object.wait(int, long)
BlockingQueue.put(...)
BlockingQueue.offer(...)
BlockingQueue.take(...)
BlockingQueue.poll(...)
Future.get(...)
Process.waitFor()
ExecutorService.invokeAll(...)
ExecutorService.invokeAny(...)
ExecutorService.awaitTermination(...)
CompletionService.poll(...)
CompletionService.take(...)
CountDownLatch.await(...)
CyclicBarrier.await(...)
Semaphore.acquire(...)
Semaphore.tryAcquire(...)
Lock.lockInteruptibly()
Lock.tryLock(...)
请注意,对于任何捕获的代码,正确的模式是立即重新中断线程。我们这样做是为了以防其他人依赖该方法:InterruptedException
thread.isInterrupted()
try {
...
} catch (InterruptedException e) {
// immediately re-interrupt the thread
Thread.currentThread().interrupt();
// log the exception or [likely] quit the thread
}
演示其中一些内容的 JUnit 代码:
assertFalse(Thread.currentThread().isInterrupted());
// you can do this from another thread by saying: someThread.interrupt();
Thread.currentThread().interrupt();
// this method does _not_ clear the interrupt flag
assertTrue(Thread.currentThread().isInterrupted());
// but this one _does_ and should probably not be used
assertTrue(Thread.interrupted());
assertFalse(Thread.currentThread().isInterrupted());
Thread.currentThread().interrupt();
assertTrue(Thread.currentThread().isInterrupted());
try {
// this throws immediately because the thread is _already_ interrupted
Thread.sleep(1);
fail("will never get here");
} catch (InterruptedException e) {
// and when the InterruptedException is throw, it clears the interrupt
assertFalse(Thread.currentThread().isInterrupted());
// we should re-interrupt the thread so other code can use interrupt status
Thread.currentThread().interrupt();
}
assertTrue(Thread.currentThread().isInterrupted());
