Java でデータベース接続タイムアウトを実装するにはどうすればよいですか?

Timer timer = new Timer();

timer.schedule(new TimerTask() {
  @Override
  public void run() {
    // Your database code here
  }
}, 2*60*1000); // 2 minutes in milliseconds

timer.scheduleAtFixedRate(new TimerTask() {
  @Override
  public void run() {
    // Your database code here
  }
}, 2*60*1000, 2*60*1000); // 2 minutes interval

ExecutorService service = Executors.newSingleThreadExecutor();

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

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

    f.get(2, TimeUnit.MINUTES); // Attempt task for 2 minutes
} catch (TimeoutException e) {
    // Task timed out
} finally {
    service.shutdown();
}
