Example 66 with EntityManager

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

the class MultiCircleJpaCascadeTest method testMerge.

@Test
public void testMerge() {
    EntityManager em = getOrCreateEntityManager();
    em.getTransaction().begin();
    b = em.merge(b);
    c = b.getC();
    d = b.getD();
    e = d.getE();
    f = e.getF();
    g = f.getG();
    em.getTransaction().commit();
    em.close();
    check();
}

Example 67 with EntityManager

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

the class MultiCircleJpaCascadeTest method testPersistThenUpdate.

@Test
@FailureExpected(jiraKey = "HHH-6999")
public // fails on d.e; should pass
void testPersistThenUpdate() {
    EntityManager em = getOrCreateEntityManager();
    em.getTransaction().begin();
    em.persist(b);
    // remove old e from associations
    e.getDCollection().remove(d);
    d.setE(null);
    f.getECollection().remove(e);

    d.setE(e);
    e.setF(f);

    em.close();
    check();
}

Example 68 with EntityManager

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

the class MultiCircleJpaCascadeTest method testPersistThenUpdateNoCascadeToTransient.

@Test
public void testPersistThenUpdateNoCascadeToTransient() {
    // expected to fail, so nothing will be persisted.
    skipCleanup = true;
    // remove elements from collections and persist
    c.getBCollection().clear();
    c.getDCollection().clear();
    EntityManager em = getOrCreateEntityManager();
    em.getTransaction().begin();
    em.persist(c);
    // now add the elements back
    c.getBCollection().add(b);
    c.getDCollection().add(d);
    try {
        em.getTransaction().commit();
        fail("should have thrown IllegalStateException");
    } catch (RollbackException ex) {
        assertTrue(ex.getCause() instanceof IllegalStateException);
        IllegalStateException ise = (IllegalStateException) ex.getCause();
        // should fail on entity g (due to no cascade to f.g);
        // instead it fails on entity e ( due to no cascade to d.e)
        // because e is not in the process of being saved yet.
        // when HHH-6999 is fixed, this test should be changed to
        // check for g and f.g
        //noinspection ThrowableResultOfMethodCallIgnored
        TransientPropertyValueException tpve = assertTyping(TransientPropertyValueException.class, ise.getCause());
        assertEquals(E.class.getName(), tpve.getTransientEntityName());
        assertEquals(D.class.getName(), tpve.getPropertyOwnerEntityName());
        assertEquals("e", tpve.getPropertyName());
    }
    em.close();
}

    EntityManager em = getOrCreateEntityManager();
    em.getTransaction().begin();
    em.persist(b);
    em.getTransaction().commit();
    em.close();
    check();
}

Example 70 with EntityManager

the class ExpressionsTest method testEmptyConjunctionIsFalse.

@Test
public void testEmptyConjunctionIsFalse() {
    EntityManager em = getOrCreateEntityManager();
    em.getTransaction().begin();
    CriteriaQuery<Product> criteria = builder.createQuery(Product.class);
    criteria.from(Product.class);
