That's basically what I currently have (sub-resource locator) but I was
Just trying to see if there was a way to get resource class-level
attribute
@Context injection into the sub-resource. I can only get injected
@Context
Resources in the sub-resource if I put the injections in the parameter
list of
Resource methods or pass the injected attributes to the sub-resource in
the
Constructor invocation... Like:
> @Path("v1")
> public class V1BaseResource {
>
> @Context protected UriInfo uriInfo;
>
> @Path("node")
> public V1NodeResource getNode() {
> return new V1NodeResource(uriInfo);
> }
> }
>
> public class V1NodeResource {
> private UriInfo uriInfo
> public V1NodeResource(UriInfo ui) {
> this.uriInfo = ui;
> }
>
> @GET @Path("/{key}")
> @Produces(MediaType.APPLICATION_XML)
> public Node getNodeByKey( @PathParam("key") String key ) {
> return NodeDB.getNodeByKey(key);
> }
> }
