Examples with HibernateEntityManager org.hibernate.jpa.HibernateEntityManager used on opensource projects

Example 1 with HibernateEntityManager

use of org.hibernate.jpa.HibernateEntityManager in project hibernate-orm by hibernate.

the class SharedCacheModesTest method testEntityManagerCacheModes.

@Test
public void testEntityManagerCacheModes() {
    EntityManager em;
    Session session;
    em = getOrCreateEntityManager();
    session = ((HibernateEntityManager) em).getSession();
    // defaults...
    assertEquals(CacheStoreMode.USE, em.getProperties().get(AvailableSettings.SHARED_CACHE_STORE_MODE));
    assertEquals(CacheRetrieveMode.USE, em.getProperties().get(AvailableSettings.SHARED_CACHE_RETRIEVE_MODE));
    assertEquals(CacheMode.NORMAL, session.getCacheMode());
    // overrides...
    em.setProperty(AvailableSettings.SHARED_CACHE_STORE_MODE, CacheStoreMode.REFRESH);
    assertEquals(CacheStoreMode.REFRESH, em.getProperties().get(AvailableSettings.SHARED_CACHE_STORE_MODE));
    assertEquals(CacheMode.REFRESH, session.getCacheMode());
    em.setProperty(AvailableSettings.SHARED_CACHE_STORE_MODE, CacheStoreMode.BYPASS);
    assertEquals(CacheStoreMode.BYPASS, em.getProperties().get(AvailableSettings.SHARED_CACHE_STORE_MODE));
    assertEquals(CacheMode.GET, session.getCacheMode());

    item.setDescr("Paris-Bruxelles");
    //em.getTransaction().commit();
    //fake the in container work
    ((HibernateEntityManager) em).getSession().disconnect();
    stream = new ByteArrayOutputStream();
    out = new ObjectOutputStream(stream);
    out.writeObject(em);
    out.close();
    serialized = stream.toByteArray();
    stream.close();

    in.close();
    byteIn.close();
    //fake the in container work
    em.getTransaction().begin();
    item = em.find(Item.class, item.getName());
    item.setDescr(item.getDescr() + "-Amsterdam");
    cat = (Cat) em.createQuery("select c from " + Cat.class.getName() + " c").getSingleResult();
    cat.setLength(34);
    em.flush();
