With the Hibernate 5 the createCriteria is deprecated use something like this

private static <T> List<T> loadAllData(Class<T> type, Session session) {
    CriteriaBuilder builder = session.getCriteriaBuilder();
    CriteriaQuery<T> criteria = builder.createQuery(type);
    criteria.from(type);
    List<T> data = session.createQuery(criteria).getResultList();
    return data;
  }

usage

Session session = HibernateUtils.getSession();
List<User> users = loadAllData(User.class, session);

Try below piece of code and replace Entity with your Entity class

@SuppressWarnings("unchecked")      
public List<Entity> getAlldata(){       
    try
    {
        return sessionFactory.getCurrentSession().createCriteria(Entity.class).list();
    } catch (Exception e) {
        return new ArrayList<>();
    }
}

Try as following to get all rows from table

@SuppressWarnings("unchecked")
    public List<Service> Service getServiceData() {

         return ServiceDaoImpl.getSession().createQuery("from Service").list(); 
    }
