Access path params from outside the main controller with Quarkus and Resteasy

I'm using Resteasy with Quarkus (io.quarkus.quarkus-resteasy).

I have a path with params declared on a controller.

@RequestScoped
@Path("/v1/domain/{domain}/resource")
public class MyRestController {

    @POST
    @Consumes(APPLICATION_JSON)
    public Response create(Entity entity) {
        // here I create a new entity...
    }
    
    @GET
    @Path("/{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response get(@PathParam("id") String id) {
        // get and return the entity...
    }

}

I would like to retrieve the domain path param from outside this controller, in a provider marked with @Dependent for example, or in any interceptor that process the incoming request.

@Dependent
public class DomainProvider {

    @Produces
    @RequestScoped
    public Domain domain() {
        // retrieve the path param here !
    }
}

I didn't find a way to do that, nor documentation about this.

I tried both:

• injecting io.vertx.ext.web.RoutingContext with @Inject and access routingContext.pathParams()
• using ResteasyProviderFactor to recover the request context data

In both case, there is no path parameter : the request path is resolved as a simple string, containing the actual URL the client used to contact my web service.

Edit: As a workaround, in my DomainProvider class, I used the routingContext to retrieve the called URL and a regular expression to parse it and extract the domain.
