场景描述：
代码：
/**
* 校验周期时间是否叠加
* @param list
* @return
*/
public static ErrorTip checkCycleTime(List<CycleTimeVo> list) {
if (CollectionUtils.size(list) < 2) {
return null;
}
for (int i = 0; i < list.size(); i++) {
CycleTimeVo timeVo = list.get(i);
LocalTime startTime = LocalTime.parse(timeVo.getStartTimePoint());
LocalTime endTime = LocalTime.parse(timeVo.getEndTimePoint());
for (int j = 0; j < list.size(); j++) {
if (i == j) {
continue;
}
CycleTimeVo nextTimeVo = list.get(j);

}

}
isAfterStart = nextStartWeek < timeVo.getEndWeek() || nextStartWeek == timeVo.getEndWeek() && (isInSide ? endTime.isAfter(nextStartTime) : !endTime.isBefore(nextStartTime));

if (isInSide == (isAfterStart && isBeforeEnd)) {
return new ErrorTip(500, String.format("周期时间有重叠[%s-%s]", i, j));
}
}
}
return null;
}CycleTimeVo对象：
@Data
public class CycleTimeVo implements Serializable {
/**
* 开始 周
*/
private Integer startWeek;
/**
* 开始 时间点
* 12:01
*/
private String startTimePoint;
/**
* 结束 周
*/
private Integer endWeek;
/**
* 结束 时间点
* 18:45
*/
private String endTimePoint;
}测试代码：
public static void main(String[] args) {
List<CycleTimeVo> list = new ArrayList<>();
CycleTimeVo timeVo1 = new CycleTimeVo();
timeVo1.setStartWeek(7);
timeVo1.setStartTimePoint("12:00");
timeVo1.setEndWeek(2);
timeVo1.setEndTimePoint("12:00");
CycleTimeVo timeVo2 = new CycleTimeVo();
timeVo2.setStartWeek(2);
timeVo2.setStartTimePoint("12:00");
timeVo2.setEndWeek(3);
timeVo2.setEndTimePoint("12:00");
CycleTimeVo timeVo3 = new CycleTimeVo();
timeVo3.setStartWeek(2);
timeVo3.setStartTimePoint("12:00");
timeVo3.setEndWeek(3);
timeVo3.setEndTimePoint("12:00");
list.add(timeVo1);
list.add(timeVo2);
list.add(timeVo3);
ErrorTip errorTip = checkCycleTime(list);
System.out.println(JsonUtil.obj2Json(errorTip));
