defining Spring request scope bean

Question

For using spring request scope bean is this definition correct?

<bean id="shoppingCart" class="ShoppingCart" scope="request">
<!-- This requires CGLIB --> 
<aop:scoped-proxy/>
</bean> 

I modified this from a session scope bean example, and changed only the scope definition, not sure about the proxy thing

I took this example from this link, you can see the full xml:

Generally - yes, it's correct.

If for every request You'd retrieve the request scoped bean directly from the BeanFactory , then You don't need the proxy.

But You need the proxy if You're going to use the request soped bean as a depenedncy to singleton scoped bean, for example like this:

@Controller
public class MyController {

    @Autowired
    private ShoppingCart shoppingCart;
}

See this reference page for more details about scoped beans.

As a side note I'd advise to use standard JDK interface-based poxies instead of CGLIB whenever possible. More about proxying with spring can be found in documentation .
