Java에서 시간 제한 데이터베이스 연결 확인을 어떻게 구현할 수 있습니까?

import java.util.Timer;
...
Timer timer = new Timer();

timer.schedule(new TimerTask() {
  @Override
  public void run() {
    // Database connection code
  }
}, 2*60*1000);

timer.scheduleAtFixedRate(new TimerTask() {
  @Override
  public void run() {
    // Database connection code
  }
}, 2*60*1000, 2*60*1000);

ExecutorService service = Executors.newSingleThreadExecutor();

try {
    Runnable r = new Runnable() {
        @Override
        public void run() {
            // Database connection task
        }
    };

    Future<?> f = service.submit(r);

    f.get(2, TimeUnit.MINUTES); // Attempt the task for two minutes
}
catch (InterruptedException) {
    // Interrupted while waiting
}
catch (TimeoutException) {
    // Took longer than two minutes
}
catch (ExecutionException) {
    // Exception within the task
}
finally {
    service.shutdown();
}
