near shop
Product
Product
Checkout

POS
+ =
Not available in store,

Product Checkout

4. We call it
Multi Channel

5. No, Omni Channel

6. No, Omni Commerce

7. Nice word but:
How to do it?

8. The solution:
Web Services
of course

9. The Problem:
hybris is pretty
old mature

10. Core Services
Core / Jalo
Over theYears We Stacked up Quite a Stack
Commerce Services
Commerce Façades
Accelerator (Web Storefront) OCC (Web Services)

11. Let’s Zoom In
Controller
Converter
Service
Façade
DTO
Model
Populator

12. A DTO
public class CartData implements Serializable {
!
private String code;
private boolean net;
private PriceData totalPrice;
//...
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
!
//...
}

13. A Descriptor for DTOs
<bean class="de.hybris.platform.commercefacades.order.CartData">
<property name="code" type="String"/>
<property name="net" type="boolean"/>
<property name="totalPrice"
type="de.hybris.platform.commercefacades.product.PriceData"/>
<!-- ... -->
</bean>

14. A Façade
public interface CartFacade
{
!
CartData getSessionCart();
!
CartData getMiniCart();
!
CartModificationData addToCart(String code,
long quantity)
throws CommerceCartModificationException;
!
// ...
!
}

15. A Controller for the Storefront
@Controller
public class AddToCartController extends AbstractController
{
@Resource(name = "cartFacade")
private CartFacade cartFacade;
!
@RequestMapping(value = "/cart/add", method = RequestMethod.POST)
public String addToCart(@RequestParam("productCodePost") String code,
Model model, @Valid AddToCartForm form, BindingResult bindingErrors)
{
// ...
CartModificationData cartModification = cartFacade.addToCart(code, qty);
if (cartModification.getQuantityAdded() == 0L)
{
model.addAttribute(ERROR_MSG_TYPE,
"basket.information.quantity.noItemsAdded." +
cartModification.getStatusCode());
}
else if (cartModification.getQuantityAdded() < qty)
{
model.addAttribute(ERROR_MSG_TYPE,
"basket.information.quantity.reducedNumberOfItemsAdded." +
cartModification.getStatusCode());
}
// ..
}
}

16. Spring MVC doesn’t
care if it’s HTML,
XML, JSON,
or whatever

17. Another Controller — this Time for a Web Service
@Controller
public class CartController extends BaseController
{
@Resource(name = "cartFacade")
private CartFacade cartFacade;
!
@RequestMapping(value = "/entry", method = RequestMethod.POST)
@ResponseBody
public CartModificationData addToCart(@RequestParam(required = true) String code,
@RequestParam(required = false, defaultValue = "1") long qty)
throws CommerceCartModificationException
{
return cartFacade.addToCart(code, qty);
}
!
}

18. Marshal Response DTOs to XML/JSON
<!-- from springmvc-servlet.xml -->
!
<mvc:annotation-driven>
<mvc:message-converters register-defaults="false">
<bean parent="resolverXStreamJSONConverter"/>
<bean parent="resolverXStreamXmlConverter"/>
</mvc:message-converters>
</mvc:annotation-driven>

19. We expose
commerce logic
and data model 1:1

20. What Else?
REST-like
ETag
OAuth 2.0 & HTTPS
Template
Shipped as source
