如何停止java执行器类中的所有可运行线程？

final ExecutorService executor = Executors.newFixedThreadPool(1);
final Future<?> future = executor.submit(myRunnable);
executor.shutdown();
if(executor.awaitTermination(10, TimeUnit.SECONDS)) {
  System.out.println("task completed");
}else{
  System.out.println("Executor is shutdown now");
}

//MyRunnable method is defined as task which I want to execute in a different thread.

Here is run执行器类的方法：

public void run() {
try {
     Thread.sleep(20 * 1000);
} catch (InterruptedException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
}}

这里正在等待20其次，但是当我运行代码时它会抛出异常：

java.lang.InterruptedException: sleep interrupted
at java.lang.Thread.sleep(Native Method)

我无法关闭并发线程Java Executor class。这是我的代码流程：

• 使用 Java 执行器类创建一个新线程来运行一些任务，即编写的MyRunnable
• executor等待 10 秒以完成任务。
• 如果任务已完成，则可运行线程也会终止。
• 如果任务没有在 10 秒内完成，那么executor类应该终止线程。

除了最后一个场景中任务的终止之外，一切正常。我该怎么做呢？

The shutDown() http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html#shutdown%28%29方法只是阻止安排额外的任务。相反，你可以打电话shutDownNow() http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html#shutdownNow%28%29并检查线程是否中断Runnable.

// in your Runnable...
if (Thread.interrupted()) {
  // Executor has probably asked us to stop
}

根据您的代码，示例可能是：

final ExecutorService executor = Executors.newFixedThreadPool(1);
executor.submit(new Runnable() {
  public void run() {
    try {
      Thread.sleep(20 * 1000);
    } catch (InterruptedException e) {
      System.out.println("Interrupted, so exiting.");
    }
  }
});

if (executor.awaitTermination(10, TimeUnit.SECONDS)) {
  System.out.println("task completed");
} else {
  System.out.println("Forcing shutdown...");
  executor.shutdownNow();
}
