I tried creating a custom ResultTransformer, but this path seems to
lead me into copying the data out of the proxy objects into their base
classes. I'm not sure how this performs, but I'll give it a try.
I'd really prefer not to have DTOs as they'd have to be identical to
the mapped classes. Can I actually use the same class as my DTO?
Is it really not possible to simply get a query to retrieve the mapped
classes without having to eager load everything (as opposed to
returning them as proxies)?
Alternatively, is it possible to implement my own proxy classes that
are basically the same as the base class? i.e. SomeClassProxy :
SomeClass {}
