方法名：scheduleAtFixedRate

TaskScheduler.scheduleAtFixedRate介绍

[英]Schedule the given Runnable, starting as soon as possible and invoking it with the given period.

Execution will end once the scheduler shuts down or the returned ScheduledFuture gets cancelled.
[中]安排给定的Runnable，尽快开始并在给定的时间段内调用它。
一旦调度程序关闭或返回的ScheduledFuture被取消，执行将结束。
