Extend generated URLs for a given Domain Object [DATAREST-339]

Benjamin M opened DATAREST-339 and commented

Following situation with 2 Maven modules:
Module 1 has an User entity
Module 2 has a MessageInbox entity

The MessageInbox knows the User (because of Maven dependency management), but the User doesn't know the MessageInbox.

I'd like to expose following URL without modifying the User entity:
/users/\{userId\}/messageInbox
Of course this is possible via ResourceProcessor, but it's not nice, because I have to take care of the path in 2 locations.

It would be much better if I could do the following:

@RepositoryRestController
@ExposesResourceExtensionFor(User.class)
public UserMessageInboxController { ... }

So it would automatically set @RequestMapping("/users"), because my UserRepository says that it's path="users".

EDIT: And of course it should act as the ResourceProcessor and add the \@RequestMapping s from this controller to the User resource
