Nice tutorial.

It's not clear to me why OrderItem has fields "productId" and "orderId". In fact I think that there are not needed as the class already has members "product" and "order".

    Those fields are there just to make more clear what my intention was. Of course, you can replace them with product.getId() in OrderItem#getProductId() method, as shown in the example.
