我需要比较一个实体的日期介于两个日期之间,不幸的是我没有得到我需要的结果。标准构建器没有比较日期,而是创建了一个比较日期和时间的查询,这会导致不返回任何结果。我正在使用 Spring Specification 来调用标准构建器。我的问题是我正在使用 ZoneDateTime (我需要这个)来比较日期,我只是想知道是否有距离我可以将两个日期都转换为 LocalDate 所以它会比较'2018-01-12' '2018-01-12 09:45:00'。
标准生成器:
public static Specification<Activity> activityDateBetween(ZonedDateTime from, ZonedDateTime to) {
return new Specification<Activity>() {
@Override
public Predicate toPredicate(Root<Activity> root, CriteriaQuery<?> criteriaQuery, CriteriaBuilder criteriaBuilder) {
Predicate startingFrom = criteriaBuilder.greaterThanOrEqualTo(root.get(Activity_.date), from);
Predicate endingAt = criteriaBuilder.lessThanOrEqualTo(root.get(Activity_.date), to);
return criteriaBuilder.and(startingFrom, endingAt);
}
};
}
MySQL:
SELECT activity0_.id AS id1_5_,
activity0_.activity_type AS activity2_5_,
activity0_.activity_date AS activity3_5_,
activity0_.tracker_job_item_id AS tracker_5_5_,
activity0_.work_type AS work_typ4_5_,
activity0_.tracker_worker_id AS tracker_6_5_
FROM tracker_job_item_activity activity0_
WHERE activity0_.tracker_job_item_id = 71
AND ( activity0_.work_type IN ( 'BUTTONHOLING', 'SEWING', 'CUTTING' ) )
AND ( activity0_.activity_type IN ( 'RECEIVE', 'SEND' ) )
AND activity0_.activity_date >= '2018-01-12 09:29:43'
AND activity0_.activity_date <= '2018-01-12 09:29:43'
如您所见,上面的查询是比较日期时间,这不是我想要的。
