java - 如何将 Hibernate "createAlias"子限制添加到父实体限制

Question

我有一个要求，需要将搜索关键字应用于父实体(客户)的名称和状态以及子实体订单的名称属性。

List<Criterion> aliasRestrictionsCriterion = new ArrayList<Criterion>();
Junction quotedLikeRestrictions = Restrictions.disjunction();
quotedLikeRestrictions.add(Restrictions.ilike("customerName", token, MatchMode.ANYWHERE));
quotedLikeRestrictions.add(Restrictions.ilike("customerState", token, MatchMode.ANYWHERE));
restrictions.add(quotedLikeRestrictions);

为了在查询中包含子表，我正在执行以下操作

Criteria alias = criteria.createAlias("order", "order")
.add(Restrictions.ilike("order.name", token, MatchMode.ANYWHERE));

Hibernate 正在生成以下查询，但我需要的是将 order.name 之类的比较添加到父 block 中。

CUSTOMER this_ inner join ORDER order_ on this_.ORDER_ID=order_.ORDER_ID where 
(lcase(this_.name) like ? or lcase(this_.state) like ?) and (lcase(order_.NAME) 
like ?)        

我想要的是在父 block 内有 (lcase(order_.NAME) like ?) 。所以我想要的是以下内容

(lcase(this_.name)像？或lcase(this_.state)像？或lcase(order_.NAME)像？)

我怎样才能实现这个目标？

更新:这就是我调用标准的方式

protected List getEntities(List<Criterion> restrictions, String aliasSearchToken) {
    Session session = currentSession();
    Criteria criteria = session.createCriteria(getEntityClass());

    // apply restrictions.
    if (restrictions != null) {
        for (Criterion criterion : restrictions) {
            criteria.add(criterion);
        }
    }

    Criteria alias = criteria.createAlias("order", "order").add(Restrictions.ilike("order.name", searchToken, MatchMode.ANYWHERE));

    List list = criteria.list();
    if (list != null) {
        return list;
    }
    return Collections.emptyList();
}

更新2:

protected List getEntities(List<Criterion> restrictions, String aliasSearchToken) {
    Session session = currentSession();
    Criteria criteria = session.createCriteria(getEntityClass());

    Junction or = Restrictions.disjunction();
    or.add(Restrictions.ilike("order.name", searchToken, MatchMode.ANYWHERE));
    criteria.createAlias("order", "order").add(or);


    // apply restrictions.
    if (restrictions != null) {
        for (Criterion criterion : restrictions) {
            criteria.add(criterion);
        }
    }

    List list = criteria.list();
    if (list != null) {
        return list;
    }
    return Collections.emptyList();
}

已制作 select ....... from CUSTOMER this_inner join ORDER order_ on this_.ORDER_ID=order_.uid where (lcase(order_.NAME) like ?) 和 (lcase(this_.name) like ? 或 lcase(this_.state )喜欢？)

orderName 就在之前，但仍然不在第二个或语句中......我很困惑。

好吧，您必须将其添加到 quotedLikeRestrictions 析取中，而不是将限制添加到 Criteria(这会创建 AND):

quotedLikeRestrictions.add(Restrictions.ilike("order.name", token, MatchMode.ANYWHERE));
