在Spring应用程序中安全使用jdk ScheduledExecutorService

在简单的java应用程序中,需要关闭ExecutorServices以便应用程序终止,例如:

    public static void main(String[] args) throws StoreException {
        final ExecutorService executorService = Executors.newSingleThreadExecutor();
        executorService
                .submit((Callable<Void>) () -> {
                    Thread.sleep(2000);
                    System.out.println("parallel");
                    return null;
                 });
      // JVM does not shutdown unless calling executorService.shutDown()
      // executorService.shutDown();
    }

另请参见 Reason for calling shutdown() on ExecutorService

那么在服务器应用程序(例如,使用Spring)中,如果有任何类创建这样的重复任务,会发生什么情况:

public class MyClass {

    public MyClass() {
        ScheduledExecutorService scheduledExecutorService = Executors.newSingleThreadScheduledExecutor();
        scheduledExecutorService
                .scheduleAtFixedRate(() -> {
                    System.out.println("parallel");
                 }, 2000, 2000, TimeUnit.SECONDS);
    }
}

我是否需要在应用程序关闭时连接scheduledExecutorService的关闭?还是不得不使用Springs调度工具?
