- fixedRate是按照一定的速率执行，是从上一次方法执行开始的时间算起，如果上一次方法阻塞住了，下一次也是不会执行，但是在阻塞这段时间内累计应该执行的次数，当不再阻塞时，一下子把这些全部执行掉，而后再按照固定速率继续执行。
- cron表达式可以定制化执行任务，但是执行的方式是与fixedDelay相近的，也是会按照上一次方法结束时间开始算起。
- initialDelay 。如：
@Scheduled(initialDelay = 10000,fixedRate = 15000)这个定时器就是在上一个的基础上加了一个initialDelay = 10000 意思就是在容器启动后,延迟10秒后再执行一次定时器,以后每15秒再执行一次该定时器。
