LocalDateTime 获取当月的第一天 0点

使用引用中的代码可以获取当前月的第一天0点时间。首先，使用`LocalDateTime.now().with(TemporalAdjusters.firstDayOfMonth())`获取当前月的第一天，然后使用`LocalTime.MIN`将时间设置为0点。所以可以使用以下代码获取当月的第一天0点时间：

LocalDateTime firstDayOfMonth = LocalDateTime.of(LocalDate.from(LocalDateTime.now().with(TemporalAdjusters.firstDayOfMonth())), LocalTime.MIN);
