[FIXED] Spring store object in session

Issue

I would like to implement a shopping cart with Spring, so I need to save an object Cart ( which has attributes like products, paymentType and deliveryType ) in session. I've tried to create it with bean and attribute "scope" set to "session", but it just doesn't work, should I use some additional annotations in my controller or Cart class? Any example usage would be really helpful :-) Thanks in advance.

Solution

@Component
@Scope("session")
public class Cart { .. }

and then

@Inject
private Cart cart;

should work, if it is declared in the web context (dispatcher-servlet.xml). An alternative option is to use the raw session and put your cart object there:

@RequestMapping(..)
public String someControllerMethod(HttpSession session) {
    session.setAttribute(Constants.CART, new Cart());
    ...
    Cart cart = (Cart) session.getAttribute(Constants.CART);
}
