In my application I have a DTO that I use for the view of my new-delivery page. Do I send the data to my DeliveryService through my controller: (not sure if this is right)
@Controller
public class DeliveryController {
@Resource(name="deliveryService")
private DeliveryService deliveryService;
@RequestMapping(value="/initForm", method=RequestMethod.GET)
public String getAdd(Model model){
DeliveryDto form = new DeliveryDto();
model.addAttribute("formData", form);
return "----view----";
}
@RequestMapping(value="/postForm", method=RequestMethod.POST)
public String postAdd(@ModelAttribute("formData") DeliveryDto form, Model model) {
deliveryService.createDelivery(form.getCustomerName(), form.getCustomerCountry());
return "----view----";
}
}Or do I retrieve that data in my DeliveryService?
The reason I am using a DTO is that I have some IDs in my Delivery table that I don't want the user to have to enter.
I use a customer Service+DTO to retrieve the ID corresponding to a pair of customerNames and customerCountries.
CustomerDAO:
@Repository
public class CustomerDaoImpl implements CustomerDao {
@Autowired(required=true)
private SessionFactory sessionFactory;
public Customer getCTID(String customerName, String customerCountry) { //Is it right to use a query here to get the Id?
return (Customer) this.sessionFactory.getCurrentSession().createQuery(
"select customerId from Customer where customerName = :name and customerCountry = :country")
.setParameter("name", customerName).setParameter("country", customerCountry).uniqueResult();
}
}CustomerService:
@Service
public class CustomerServiceImpl implements CustomerService {
@Autowired(required=true)
private CustomerDao customerDao;
@Transactional
public Customer retrieveCTID(String customerName, String customerCountry) {
return this.customerDao.getCTID(customerName, customerCountry);
}
}I don't know how I would write the DeliveryService/DAO so that it takes some DTO data and the data from CustomerService and persists it as a new delivery in the DeliveryTable.
Thank you for your help!
