jpa中时间戳格式应该用哪种类型

遇到个bug，数据库时间存储用了datetime，但是下面的java jpa代码，查询回来，却只有日期。

        String innerSql = getInnerQuery(departmentId, keyword, type, startDate, endDate);

        SQLQuery query = manager.createNativeQuery(innerSql).unwrap(SQLQuery.class);
        if (PublicUtils.isNotEmpty(departmentId)) {
            query.setParameter("departmentId", departmentId);
        }
        if (StringUtils.isNotEmpty(type)) {
            query.setParameter("typeParam", Integer.valueOf(type));
        }
        if (StringUtils.isNotEmpty(keyword)) {
            query.setParameter("keyword", keyword);
        }
        if (startDate != null && endDate != null) {
            query.setParameter("startDate", startDate);
            query.setParameter("endDate", endDate);
        }
        query.addScalar("noticeId", StandardBasicTypes.STRING);
        query.addScalar("title", StandardBasicTypes.STRING);
        query.addScalar("type", StandardBasicTypes.INTEGER);
        query.addScalar("createUserId", StandardBasicTypes.STRING);
        query.addScalar("createTime", StandardBasicTypes.TIMESTAMP);
        query.addScalar("departmentId", StandardBasicTypes.STRING);
        query.addScalar("userId", StandardBasicTypes.STRING);

        query.setResultTransformer(new MyBasicTransformerAdapter());

        query.setFirstResult(startIndex);
        query.setMaxResults(pageSize);
        List<NoticePageListVO> items = query.list();

中的

query.addScalar("createTime", StandardBasicTypes.DATE);

这边要改成

query.addScalar("createTime", StandardBasicTypes.TIMESTAMP);

注意：改成TIME也不行，一定要是TIMESTAMP
