How to add object to session in spring app

Question

I have a kind of online store in Spring. I want to create a shopping cart for each new user who visits the site and stored it in the session. How can this be done? It's just that I've never worked with sessions in Spring. Perhaps there is a good resource to study this stuff.

Answer 1

Make your controller session scoped

@Controller
@Scope("session")

then add one attribute to session

@RequestMapping(method = RequestMethod.GET)
public String testMestod(HttpServletRequest request){
   ShoppingCart cart = (ShoppingCart)request.getSession().setAttribute("cart",valueOfCart);
   return "testJsp";
}

then Scope the user object that should be in session every time:

@Component
@Scope("session")
public class User
 {
    String user;
    /*getter setter*/
  }

then inject class in each controller that you want

@Autowired
   private User user

The AOP proxy injection : in spring -xml:

 <bean id="user"    class="com.User" scope="session">     
      <aop:scoped-proxy/>
  </bean>

Answer 2

@Controller class example{

@RequestMapping("/") public String test(HttpSession session){

session.addAttribute("cart",new Cart()); }

}
