Spring Boot中几种定时任务

public static void main(String[] args){		TimerTask timerTask = new TimerTask() {			@Override
			public void run() {
				System.out.println("Timer方式执行一次定时任务");
			}
		};		new Timer().schedule(timerTask,,*);
	}

public static void main(String[] args){		ScheduledExecutorService scheduledExecutor = Executors.newSingleThreadScheduledExecutor();
		scheduledExecutor.scheduleAtFixedRate(				new Runnable() {					@Override
					public void run() {
						System.out.println("ScheduledExecutorService方式执行一次定时任务");
					}
				}
		,,, TimeUnit.SECONDS);
	}
