回答by Bozho
You can ask the thread to interrupt, by calling Thread.interrupt()
您可以通过调用来要求线程中断 Thread.interrupt()
Note that a few other methods with similar semantics exist - stop()and destroy()- but they are deprecated, because they are unsafe. Don't be tempted to use them.
请注意，存在一些具有类似语义的其他方法 -stop()并且destroy()- 但它们已被弃用，因为它们不安全。不要试图使用它们。

As Bozho said, Thread.interrupt() is the generic and right way to do it. But remember that it requires the thread to cooperate; It is very easy to implement a thread that ignores interruption requests.
正如 Bozho 所说，Thread.interrupt() 是通用且正确的方法。但要记住，它需要线程配合；实现一个忽略中断请求的线程是很容易的。
In order for a piece of code to be interruptible this way, it shouldn't ignore any InterruptedException, and it should check the interruption flag on each loop iteration (using Thread.currentThread().isInterrupted()). Also, it shouldn't have any non-interruptible blocking operations. If such operations exist (e.g. waiting on a socket), then you'll need a more specific interruption implementation (e.g. closing the socket).
为了让一段代码以这种方式可中断，它不应该忽略任何 InterruptedException，并且应该在每次循环迭代中检查中断标志（使用 Thread.currentThread().isInterrupted()）。此外，它不应该有任何不可中断的阻塞操作。如果存在此类操作（例如等待套接字），那么您将需要更具体的中断实现（例如关闭套接字）。

Shortly you need Thread.interrupt()
不久你需要 Thread.interrupt()
For more details check the section How do I stop a thread that waits for long periods (e.g., for input)in this article Why Are Thread.stop, Thread.suspend,Thread.resumeand Runtime.runFinalizersOnExitDeprecated?.
有关详情，请部分How do I stop a thread that waits for long periods (e.g., for input)在这篇文章中，为什么Thread.stop，Thread.suspend，Thread.resume和Runtime.runFinalizersOnExit已过时？.
