Java中判断某个日期是否在某两个日期区间内

//日期区间判定可以使用Joda的Interval类
//计算特定日期是否在该区间内 [左闭右开区间，首包含尾不包含]参考contains源码的方法说明
Interval interval = new Interval(begin, end);
boolean contained = i.contains(new DateTime(“2012-03-01 12:00:00”));

* For example:
*


 * [09:00 to 10:00) contains 08:59  = false (before start)
 * [09:00 to 10:00) contains 09:00  = true
 * [09:00 to 10:00) contains 09:59  = true
 * [09:00 to 10:00) contains 10:00  = false (equals end)
 * [09:00 to 10:00) contains 10:01  = false (after end)
 *
 * [14:00 to 14:00) contains 14:00  = false (zero duration contains nothing)  
Java原生Date API实现[Java8对日期API进行的增强，没研究，Joda就可以了，已经很强了]：
if (vopSkuHybrisModel.getStartDateTime().after(vopSkuHybrisModel.getEndDateTime()))
{
    throw new InterceptorException(“Error Info：The same VOP SKU Code starting time should be before the end time.”);
}
final List vopSkuHybrisModelList = vopSkuHybrisService.getByVpCode(vopSkuHybrisModel.getVopSkuCode());
if (CollectionUtils.isNotEmpty(vopSkuHybrisModelList))
{
    for (final VopSkuHybrisModel vpInDB : vopSkuHybrisModelList)
    {
        if (vpInDB.getPk().equals(vopSkuHybrisModel.getPk()))
        {
            continue;
        }
        // 左闭右闭区间
        if ((vopSkuHybrisModel.getStartDateTime().after(vpInDB.getStartDateTime())
                && vopSkuHybrisModel.getStartDateTime().before(vpInDB.getEndDateTime()))
                || (vopSkuHybrisModel.getEndDateTime().after(vpInDB.getStartDateTime())
                        && vopSkuHybrisModel.getEndDateTime().before(vpInDB.getEndDateTime()))
                || vpInDB.getEndDateTime().after(vopSkuHybrisModel.getStartDateTime())
                        && vpInDB.getEndDateTime().before(vopSkuHybrisModel.getEndDateTime())
                || (vpInDB.getStartDateTime().after(vopSkuHybrisModel.getStartDateTime())
                        && vpInDB.getStartDateTime().before(vopSkuHybrisModel.getEndDateTime())))
        {
            throw new InterceptorException(“Error Info：The same VOP SKU Code starting time should be before the end time.”);
        }
    }
}
上面的条件判断，可以换种思路，就是找反面
if (！（(vopSkuHybrisModel.getStartDateTime().befor(vpInDB.getStartDateTime()) || 
(vopSkuHybrisModel.getEndDateTime().after(vpInDB.getEndDateTime())))
