Spring Boot中几种定时任务

Timer类

    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,,*);
    	}

ScheduledExecutorService类

ScheduledExecutorService,是基于线程设计的定时任务类，每个调度任务都会分配到线程池中的一个线程去并行执行

    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);
    	}
