This method seems to be duplicated in your project.

            return new Cart();
        }

        return $serializer->deserialize($cartData);
    }

    private function saveCart(Request $request, Cart $cart)

This method seems to be duplicated in your project.

    {
        $serializer = new CartSerializer($this->getDoctrine()->getManager());
        $data = $serializer->serialize($cart);

        $request->getSession()->set('cart', $data);
    }

    private function cleanCart(Request $request)
    {
        $request->getSession()->set('cart', null);
    }
