LocalDate.atStartOfDay介绍

[英]Combines this date with the time of midnight to create a LocalDateTimeat the start of this date.

This returns a LocalDateTime formed from this date at the time of midnight, 00:00, at the start of this date.
[中]将此日期与午夜时间相结合，以在此日期开始时创建LocalDateTime。
这将返回从该日期开始的午夜00:00开始形成的LocalDateTime。
