How to join tables using hibernate criteria

问题

I am trying to join multiple table to join using criteria but getting error in doing so can someone please help me in it My code is

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");

I also tried this code final Session session = getSession(); final Criteria criteria =session.createCriteria(ReferralPaymentInfo.class); criteria.setFetchMode("SIGNUP_REFERRAL", FetchMode.JOIN); List list = criteria.list();

This gives result only from table ReferralPaymentInfo and not considering table SIGNUP_REFERRAL Can some one please help me out T

回答1:

try this

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));
