Answer 1

session.beginTransaction() starts a new transaction, so in your code a new transaction is opened and immediately committed, while the old one will remain hanging.

Session session = sessionFactory.openSession();
Transaction tx;
try {
    tx = session.beginTransaction();
    Role hr = new Role();
    hr.setRole("hr");
    session.save(hr);
    tx.commit();
}
catch (Exception e) {
    e.printStackTrace();
    System.out.println(e.getMessage());
    tx.rollback();
}
finally {
    session.close();
    HibernateUtil.shutdown();
    System.out.println("after");
}
