我正在尝试使用条件加入多个表来加入,但是这样做会出错,有人可以帮助我 我的代码是
final Session session = getSession();
final Criteria criteria = session.createCriteria(ReferralPaymentInfo.class).createCriteria("SIGNUP_REFERRAL");
System.out.println("before");
List list = criteria.list();
System.out.println("after");
我也试过这段代码 最后的Session session = getSession(); final Criteria criteria = session.createCriteria(ReferralPaymentInfo.class); criteria.setFetchMode(" SIGNUP_REFERRAL",FetchMode.JOIN); 列表list = criteria.list();
这仅从表ReferralPaymentInfo中提供结果,而不考虑表SIGNUP_REFERRAL 有人可以帮助我 Ť
答案 0 :(得分:0)
试试这个
DetachedCriteria ownerCriteria = DetachedCriteria.forClass(Owner.class);
ownerCriteria.setProjection(Property.forName("id"));
ownerCriteria.add(Restrictions.eq("ownername", "name"));
Criteria criteria = getSession().createCriteria(Pet.class);
criteria.add(Property.forName("ownerId").in(ownerCriteria));
