根据开始时间和结束时间 分割成若干随机时间

 public static List<PullUserConfigEntity> randomDateBySize(String start,String end,int size,Long id) throws ParseException {//输入 随机起始时间//解析时间Date d1 = simpleDateFormat.parse(start);long before = d1.getTime();//获取当前时间Date d2 = simpleDateFormat.parse(end);long after = d2.getTime();long randomDate = after-before;int[] randomArray = RandomUtils.getRandomArray((int) randomDate, size);List<PullUserConfigEntity>list=new ArrayList<>();for(int index:randomArray){PullUserConfigEntity pullUserConfig=new PullUserConfigEntity();pullUserConfig.setStartTime(TimeUtils.dateToStrLong(d1));d1.setTime(d1.getTime()+index);pullUserConfig.setEndTime(TimeUtils.dateToStrLong(d1));pullUserConfig.setId(id);list.add(pullUserConfig);}return list;}

根据开始时间和结束时间和固定间隔时间 分割成多个时间

判断当前时间是否在开始和结束时间范围
