Spring + RESTEasy subresource is not injected with the dependencies - jax-rs

Question

I'm using Spring for IoC and Data JPA support and JAX-RS support is provided by RESTEasy implementation.
I have the following pom.xml dependencies:
<dependencies>

I have two resources:
Parent:
#Component
#Path("/parent")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public class ParentResource {
#Context
ResourceContext resourceContext;
#GET
#Path("sub")
public ChildResource getSub() {
return resourceContext.getResource(ChildResource.class);
}
}
Child:
#Component
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public class ChildResource {
#Autowired
Repository1 repository1;
}
This example is totally working with Jersey implementation and I can get repository from the sub resource, but in RESTEasy implementation it does not work and instead of repository instance there is null.
There is a workaround, like this:
ChildResource resource = resourceContext.getResource(ChildResource.class);
resource.setRep(repositoryFromParent);
return resource;
But it is ugly and it should not be in that way (also parent should know about all dependencies of the sub resource which is also not good).
Has anyone encountered the same issue working with subresources using Spring and RESTEasy together?
