方法名：now

LocalDateTime.now介绍

[英]Obtains the current date-time from the system clock in the default time-zone.

This will query the Clock#systemDefaultZone() in the default time-zone to obtain the current date-time.

Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
[中]从默认时区中的系统时钟获取当前日期时间。
这将查询默认时区中的时钟#systemDefaultZone（），以获取当前日期时间。
使用此方法将防止使用备用时钟进行测试，因为该时钟是硬编码的。
