cast query to hibernate query, then use hibernate method

          //normal use, javax.persistence.Query interface
    Query dbQuery = entityManager.createNativeQuery(sql);
    //cast to hibernate query
    org.hibernate.Query hibernateQuery =((org.hibernate.jpa.HibernateQuery)dbQuery)
            .getHibernateQuery();
    hibernateQuery.setResultTransformer(AliasToEntityMapResultTransformer.INSTANCE);

    List> res = hibernateQuery.list();

    List txTestModels = new ArrayList<>();
    res.forEach(e->{
        TxTestModel txTestModel = new ObjectMapper().convertValue(e, TxTestModel.class);
    //  txTestModels.add(new TxTestModel().setIdd((Integer) e.get("idd")).setMmm((String) e.get("mmm")).setDdd((Date) e.get("ffffd")));
        txTestModels.add(txTestModel);
    });
    System.out.println(txTestModels.size());
