Need to call StoredProcedure in jave using Hibernate

Just want to call Stored procedure of SQL server from java using Hibernate as ORM.

The stored Procedure has so many result set which I am keeping it in Java as DTO's and each one as list in one DTO to send as JSON payload for Front-end integration.

But I am getting exception saying"org.hibernate.MappingException: Unknown entity: com.test.plans.dto.TemplatesDTO"

 public ItemDetailsDTO getItemDetails(int no) {
     Session session = getSession();
     Connection connection = null;
     List<ItemDetailsDTO> resultList  = new ArrayList<>();
     try {
            ResultSet rs = null;
            SessionImpl sessionImpl = (SessionImpl) session;
            connection = sessionImpl.connection();
            Query query = session.createSQLQuery("exec usp_GetItemDetails :no")
                         .addEntity(TemplatesDTO.class)
                         .setParameter("no", no);
            resultList = query.list();
     } catch (Exception e) {
            System.out.println("error");
            e.printStackTrace();
     }
     return resultList.get(0);
}

DTO :

import java.util.List;


public class ItemDetailsDTO {

    private List<TemplatesDTO> templates;


    public List<TemplatesDTO> gettemplates() {
        return templates;
    }
    public void settemplates(List<TemplatesDTO> templates) {
        this.templates = templates;
    }
}

Please find below complete trace of exception
