public static void main(String[] agrs){
    ScheduledExecutorService executorService = Executors.newScheduledThreadPool(1);
    //开启定时执行
    executorService.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            System.out.println("定时所做的操作");
        }
    }, 5, 2, TimeUnit.SECONDS);
}  //5指的是5秒后开始。间隔2秒触发一次。
