Hi Martynas,
My guess is that what you're trying to do won't work, because the
entire point of @Path is to say "the current resource handles *this*
path". Now, if you really want the sub-resource to handle it, and there
is no such thing as a parent of "/" then the only way to handle this is
declare @GET/_at_POST/etc inside RootResource and delegate to
getResource(). For example:
@Path("/")
public class RootResource
{
@GET
public Response get()
{
// implementation reuse
return getResource().get();
}
@Path("{path: .*}")
public Resource getResource()
{
return new Resource();
}
}
I've done something similar in my own code, for different reasons.
One benefit of this approach is that type-safety remains enforced at
compile-time. If the sub-resource ever changes in a way that requires
RootResource to change you are likely to get a compiler error.
