Example 16 with EntityTransaction

use of javax.persistence.EntityTransaction in project hibernate-orm by hibernate.

@Test
@TestForIssue(jiraKey = "HHH-9411")
public void testTreatWithRestrictionOnAbstractClass() {
    EntityManager em = getOrCreateEntityManager();
    EntityTransaction entityTransaction = em.getTransaction();
    entityTransaction.begin();
    Greyhound greyhound = new Greyhound();
    Dachshund dachshund = new Dachshund();
    em.persist(greyhound);
    em.persist(dachshund);
    CriteriaBuilder cb = em.getCriteriaBuilder();
    CriteriaQuery<TreatAnimal> criteriaQuery = cb.createQuery(TreatAnimal.class);
    Root<TreatAnimal> animal = criteriaQuery.from(TreatAnimal.class);
    Root<Dog> dog = cb.treat(animal, Dog.class);
    // only fast dogs
    criteriaQuery.where(cb.isTrue(dog.<Boolean>get("fast")));
    List<TreatAnimal> results = em.createQuery(criteriaQuery).getResultList();
    // we should only have a single Greyhound here, not slow long dogs!
    assertEquals(Arrays.asList(greyhound), results);
    entityTransaction.commit();
    em.close();
}
