How to select all distinct records as entities - hibernate - JPA?

public List<Orders> custOrder() {
    try ( Session session = HibernateUtil.getSessionFactory().openSession()) {
        CriteriaBuilder cb = session.getCriteriaBuilder();
        CriteriaQuery<Orders> cq = cb.createQuery(Orders.class);
        Root<Orders> root = cq.from(Orders.class);

        Subquery<Long> subquery = cq.subquery(Long.class);
        Root<Orders> subRoot = subquery.from(Orders.class);
        subquery.select(cb.max(subRoot.get("id")));
        subquery.groupBy(subRoot.get("transid"));

        cq.where(cb.in(root.get("id")).value(subquery));

        return session.createQuery(cq).getResultList();
    }
}
