Examples with StatelessSession org.hibernate.StatelessSession used on opensource projects

Example 1 with StatelessSession

use of org.hibernate.StatelessSession in project hibernate-orm by hibernate.

the class StatelessSessionTest method testRefresh.

@Test
public void testRefresh() {
    StatelessSession ss = sessionFactory().openStatelessSession();
    Transaction tx = ss.beginTransaction();
    Paper paper = new Paper();
    paper.setColor("whtie");
    ss.insert(paper);
    tx.commit();
    ss.close();
    ss = sessionFactory().openStatelessSession();
    tx = ss.beginTransaction();
    Paper p2 = (Paper) ss.get(Paper.class, paper.getId());
    p2.setColor("White");
    ss.update(p2);
    tx.commit();
    ss.close();
    ss = sessionFactory().openStatelessSession();
    tx = ss.beginTransaction();
    assertEquals("whtie", paper.getColor());
    ss.refresh(paper);
    assertEquals("White", paper.getColor());
    ss.delete(paper);
    tx.commit();
    ss.close();
}

Example 2 with StatelessSession

use of org.hibernate.StatelessSession in project hibernate-orm by hibernate.

    tx = ss.beginTransaction();
    int count = ss.createQuery("update Document set name = :newName where name = :oldName").setString("newName", "Foos").setString("oldName", "Blahs").executeUpdate();
    assertEquals("hql-update on stateless session", 1, count);
    count = ss.createQuery("update Paper set color = :newColor").setString("newColor", "Goldenrod").executeUpdate();
    assertEquals("hql-update on stateless session", 1, count);
    tx.commit();
    tx = ss.beginTransaction();
    count = ss.createQuery("delete Document").executeUpdate();
    assertEquals("hql-delete on stateless session", 1, count);
    count = ss.createQuery("delete Paper").executeUpdate();
    assertEquals("hql-delete on stateless session", 1, count);
    tx.commit();
    ss.close();
}

Example 3 with StatelessSession

    Session s = openSession();
    s.beginTransaction();
    Date now = new Date();
    User me = new User("me");
    User you = new User("you");
    Resource yourClock = new Resource("clock", you);
    // :)
    Task task = new Task(me, "clean", yourClock, now);
    s.save(me);
    s.save(you);
    s.save(yourClock);
    s.save(task);
    s.getTransaction().commit();
    s.close();
    StatelessSession ss = sessionFactory().openStatelessSession();
    ss.beginTransaction();
    Task taskRef = (Task) ss.createQuery("from Task t join fetch t.resource join fetch t.user").uniqueResult();
    assertTrue(taskRef != null);
    assertTrue(Hibernate.isInitialized(taskRef));
    assertTrue(Hibernate.isInitialized(taskRef.getUser()));
    assertTrue(Hibernate.isInitialized(taskRef.getResource()));
    assertFalse(Hibernate.isInitialized(taskRef.getResource().getOwner()));
    ss.getTransaction().commit();
    ss.close();
    cleanup();
}

Example 4 with StatelessSession

use of org.hibernate.StatelessSession in project hibernate-orm by hibernate.

    Session session = sessionFactory().openSession();
    Transaction tx = session.beginTransaction();
    Message msg = new Message();
    final String messageId = "message_id";
    msg.setId(messageId);
    msg.setContent("message_content");
    msg.setSubject("message_subject");
    session.save(msg);
    tx.commit();
    session.close();
