话不多说，直接上代码！

    private static List<String> getDateListOfDateRange(String startDate, String endDate) {
        List<String> dateList = new ArrayList<>();
        long betweenDay = DateUtil.betweenDay(DateUtil.parse(startDate, "yyyy-MM-dd HH:mm:ss"), DateUtil.parse(endDate, "yyyy-MM-dd HH:mm:ss"), true);
        for (int i = 0; i <= betweenDay; i++) {
            DateTime dateTime = DateUtil.offsetDay(DateUtil.parse(startDate), i);
            dateList.add(DateUtil.format(dateTime, "yyyy-MM-dd"));
        }
        return dateList;
    }
