    CriteriaBuilder builder = em.getCriteriaBuilder();
    CriteriaQuery<Thing> criteria = builder.createQuery(Thing.class);
    Root<Thing> root = criteria.from(Thing.class);
    criteria.select(root);
    criteria.where(builder.equal(builder.treat(root, ThingWithQuantity.class).get(ThingWithQuantity_.quantity), 2));
    em.createQuery(criteria).getResultList();
    em.close();
}

Example 2 with Thing

use of org.hibernate.jpa.test.metamodel.Thing in project hibernate-orm by hibernate.

    thing.setId("thing2");
    thing.setName("Another Thing");
    em.persist(thing);
    ThingWithQuantity thingWithQuantity = new ThingWithQuantity();
    thingWithQuantity.setId("thingWithQuantity3");
    thingWithQuantity.setName("3 Things");
    thingWithQuantity.setQuantity(3);
    em.persist(thingWithQuantity);
    em.getTransaction().commit();
    em.close();
}
