public static List<String> getBetweenDate(String start, String end) {
    List<String> list = new ArrayList<>();
    LocalDate startDate = null;
    LocalDate endDate = null;
    try {
        startDate = LocalDate.parse(start);
        endDate = LocalDate.parse(end);
    } catch (Exception e) {
        throw new ServiceException("日期格式不正确。（日期示例：2019-12-26）");
    }

    if (ObjectUtils.equals(start, end)) {
        list.add(start);
        return list;
    }

    long distance = ChronoUnit.DAYS.between(startDate, endDate);
    if (distance < 1) {
        return list;
    }
    Stream.iterate(startDate, d -> {
        return d.plusDays(1);
    }).limit(distance + 1).forEach(f -> {
        list.add(f.toString());
    });
    return list;
}

注：传参（2019-12-31,2019-12-31） 返回  ["2019-12-31"]
