我有一个要求,我需要在父实体(客户)的名称和状态以及子实体Order的名称属性上应用搜索关键字。
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);
并在查询中包含子表,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,但我需要将诸如order.name这样的比较添加到父块中。
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 ?)
我想要的是将(lcase(order_.NAME)像?)放在父块中。所以我想要的是以下
(lcase(this_.name)如?或lcase(this_.state)如?或lcase(order_.NAME)如?)
我该如何实现?
更新:这就是我所说的标准
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();
}
生产的
在客户this_.ORDER_ID = order_.uid上的客户this_内部联接ORDER order_中选择.......其中(lcase(order_.NAME)如?)和(lcase(this_.name)如?或lcase(this_.state ) 喜欢 ?)
orderName只是在第二个或语句之前,但仍不在第二个或语句中……我很困惑。
最佳答案
好吧,您不必将限制添加到“条件”(创建“与”),而必须将其添加到quotedLikeRestrictions
析取式中:
quotedLikeRestrictions.add(Restrictions.ilike("order.name", token, MatchMode.ANYWHERE));
