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

Example 26 with Transaction

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

the class SybaseTimestampVersioningTest method testCollectionVersion.

@Test
@SuppressWarnings({ "unchecked" })
public void testCollectionVersion() throws Exception {
    Session s = openSession();
    Transaction t = s.beginTransaction();
    User steve = new User("steve");
    s.persist(steve);
    Group admin = new Group("admin");
    s.persist(admin);
    t.commit();
    s.close();
    byte[] steveTimestamp = steve.getTimestamp();
    s = openSession();
    t = s.beginTransaction();
    steve = (User) s.get(User.class, steve.getId());
    admin = (Group) s.get(Group.class, admin.getId());
    steve.getGroups().add(admin);
    admin.getUsers().add(steve);
    t.commit();
    s.close();
    assertFalse("owner version not incremented", BinaryType.INSTANCE.isEqual(steveTimestamp, steve.getTimestamp()));
    steveTimestamp = steve.getTimestamp();
    s = openSession();
    t = s.beginTransaction();
    steve = (User) s.get(User.class, steve.getId());
    steve.getGroups().clear();
    t.commit();
    s.close();
    assertFalse("owner version not incremented", BinaryType.INSTANCE.isEqual(steveTimestamp, steve.getTimestamp()));
    s = openSession();
    t = s.beginTransaction();
    s.delete(s.load(User.class, steve.getId()));
    s.delete(s.load(Group.class, admin.getId()));
    t.commit();
    s.close();
}

    assertEquals("Default value incorrectly loaded", obj.getValueTwo(), 2);
    assertEquals("Default value incorrectly loaded", obj.getValueThree(), -1);
    assertEquals("Default value incorrectly loaded", obj.getValueFour(), -5);
    t.commit();
    s.close();
    deleteData();
}

Example 29 with Transaction

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