使用jodatime得到所有小时,所有日期与所有月份集合
public List<Long> getHoursTimeOfDate(DateTime date) { final ImmutableList.Builder<Long> hourTimeList = ImmutableList.builder(); DateTime firstHourTime = date.withTimeAtStartOfDay(); final DateTime nextDayFirstHourTime = firstHourTime.plusDays(1); while (firstHourTime.isBefore(nextDayFirstHourTime)) { hourTimeList.add(firstHourTime.getMillis()); firstHourTime = firstHourTime.plusHours(1); } return hourTimeList.build(); } public List<Long> getDaysOfMonth(DateTime date) { final ImmutableList.Builder<Long> dayList = ImmutableList.builder(); LocalDate firstDay = date.toLocalDate().withDayOfMonth(1); final LocalDate nextMonthFirstDay = firstDay.plusMonths(1); while (firstDay.isBefore(nextMonthFirstDay)) { dayList.add(firstDay.toDateTimeAtStartOfDay().getMillis()); firstDay = firstDay.plusDays(1); } return dayList.build(); } public List<Long> getMonthsOfYear(DateTime date) { final ImmutableList.Builder<Long> monthList = ImmutableList.builder(); LocalDate firstMonth = date.toLocalDate().withDayOfMonth(1).withMonthOfYear(1); final LocalDate nextYearFirstMonth = firstMonth.plusYears(1); while (firstMonth.isBefore(nextYearFirstMonth)) { monthList.add(firstMonth.toDateTimeAtStartOfDay().getMillis()); firstMonth = firstMonth.plusMonths(1); } return monthList.build(); }
