SpringWeb项目启动后，执行一个方法，并且只执行一次

ScheduledExecutorService.schedule 方法

ScheduledExecutorService scheduledThreadPool = Executors.newScheduledThreadPool(5);
scheduledThreadPool.schedule(new Runnable() {
    @Override
    public void run() {
        System.out.println("delay 3 seconds");
    }
}, 3, TimeUnit.SECONDS);

表示延迟3秒执行，并且只执行一次。

ScheduledExecutorService scheduledThreadPool = Executors.newScheduledThreadPool(5);
scheduledThreadPool.scheduleAtFixedRate(new Runnable() {
    @Override
    public void run() {
        System.out.println("delay 1 seconds, and excute every 3 seconds");
    }
}, 1, 3, TimeUnit.SECONDS);

表示延迟1秒后每3秒执行一次。
