本文所有使用的时间戳均为毫秒级 得到的集合区间也是毫秒级的时间戳
-
按周分割时间
- 代码如下：
@Test public void timeSplitByWeek() { // 1.开始时间 2019-06-09 13:16:04 Long startTime = 1560057364000L; // 2.结束时间 2019-07-09 13:16:04 Long endTime = 1562649364000L; // 3.开始时间段区间集合 ListbeginDateList = new ArrayList (); // 4.结束时间段区间集合 List endDateList = new ArrayList (); // 5.调用工具类 MyUtils.getIntervalTimeByWeek(startTime, endTime, beginDateList, endDateList); // 6.打印输出 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); for (int i = 0; i < beginDateList.size(); i++) { Long beginStr = beginDateList.get(i); Long endStr = endDateList.get(i); String begin1 = sdf.format(new Date(beginStr)); String end1 = sdf.format(new Date(endStr)); System.out.println("第" + i + "段时间区间:" + begin1 + "-------" + end1); } } -
运行结果如下图所示：

按月分割时间
- 代码如下：
@Test public void timeSplitByMonth() { // 1.开始时间 2017-02-03 13:16:04 Long startTime = 1486098964000L; // 2.结束时间 2019-07-03 13:16:05 Long endTime = 1562130965000L; // 3.开始时间段区间集合 ListbeginDateList = new ArrayList (); // 4.结束时间段区间集合 List endDateList = new ArrayList (); // 5.调用工具类 MyUtils.getIntervalTimeByMonth(startTime, endTime, beginDateList, endDateList); // 6.打印输出 SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); for (int i = 0; i < beginDateList.size(); i++) { Long beginStr = beginDateList.get(i); Long endStr = endDateList.get(i); String begin1 = sdf.format(new Date(beginStr)); String end1 = sdf.format(new Date(endStr)); System.out.println("第" + i + "段时间区间:" + begin1 + "-------" + end1); } } -
