获取当天最大或最小日期

public static Date getStartOfDay(Date date) {
        LocalDateTime localDateTime = LocalDateTime.ofInstant(Instant.ofEpochMilli(date.getTime()),
                ZoneId.systemDefault());
        LocalDateTime startOfDay = localDateTime.with(LocalTime.MIN);
        return Date.from(startOfDay.atZone(ZoneId.systemDefault()).toInstant());
    }

    public static Date getEndOfDay(Date date) {
        LocalDateTime localDateTime = LocalDateTime.ofInstant(Instant.ofEpochMilli(date.getTime()),
                ZoneId.systemDefault());
        LocalDateTime endOfDay = localDateTime.with(LocalTime.MAX);
        return Date.from(endOfDay.atZone(ZoneId.systemDefault()).toInstant());
    }
