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

Example 1 with Transaction

use of org.hibernate.Transaction in project dropwizard by dropwizard.

the class SessionFactoryHealthCheck method check.

@Override
protected Result check() throws Exception {
    return timeBoundHealthCheck.check(() -> {
        try (Session session = sessionFactory.openSession()) {
            final Transaction txn = session.beginTransaction();
            try {
                session.createNativeQuery(validationQuery).list();
                txn.commit();
            } catch (Exception e) {
                if (txn.getStatus().canRollback()) {
                    txn.rollback();
                }
                throw e;
            }
        }
        return Result.healthy();
    });
}

Example 2 with Transaction

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

    Session s = openSession();
    Transaction t = s.beginTransaction();
    Location mel = new Location("Earth");
    s.save(mel);
    Human gavin = new Human();
    gavin.setIdentity("gavin");
    gavin.setSex('M');
    gavin.setLocation(mel);
    mel.addBeing(gavin);
    Human max = new Human();
    max.setIdentity("max");
    max.setSex('M');
    max.setLocation(mel);
    mel.addBeing(gavin);
    s.flush();
    s.clear();

        Human h = (Human) aList;
        assertTrue(Hibernate.isInitialized(h.getLocation()));
        assertTrue(Hibernate.isInitialized(h.getLocation().getBeings()));
        s.delete(h);
    }
    s.delete(s.get(Location.class, mel.getId()));
    t.commit();
    s.close();
}
