我现在有类似的东西,但我不确定这是否是最好的方法,我想避免调用Thread.stop(),因为它已被弃用。谢谢。

private void foo() throws Exception
{
        Runnable runnable = new Runnable()
        {

            @Override
            public void run()
            {
                    // stuff that could potentially lock up the thread.
            }
        };
        Thread thread;
        thread = new Thread(runnable);
        thread.start();
        thread.join(3500);
        if (thread.isAlive())
        {
            thread.stop();
            throw new Exception();
        }

}

public void stop() {
        if (thread != null) {
           thread.interrupt();
        }
    }

没有办法(无条件地)做你想做的事。例如,如果 stuff that could potentially lock up the thread. 看起来像这样,没有办法阻止它,永远缺少系统。exit():

public void badStuff() {
 while (true) {
  try {
   wait();
  }
  catch (InterruptedException irex) {
  }
 }
}

java.util.concurrent Executor Future<T>

一个未来的例子,至少,给你 isDone 和 isCancelled 方法。

ExecutorService (子接口) 遗嘱执行人 ExecutorService.awaitTermination(long timeout, TimeUnit unit) 方法

private void foo() throws Exception
{
        ExecutorService es = Executors.newFixedThreadPool(1);

        Runnable runnable = new Runnable()
        {

            @Override
            public void run()
            {
                    // stuff that could potentially lock up the thread.
            }
        };

        Future result = es.submit(runnable);

        es.awaitTermination(30, TimeUnit.SECONDS);

        if (!result.isDone()){
            es.shutdownNow();
        }

}
