      public static void generate(Map<org.jboss.jandex.DotName,org.jboss.jandex.MethodInfo> resourcesThatNeedCustomProducer, Set<org.jboss.jandex.DotName> parameterContainersThatNeedCustomProducer, io.quarkus.deployment.annotations.BuildProducer<io.quarkus.arc.deployment.GeneratedBeanBuildItem> generatedBeanBuildItemBuildProducer, io.quarkus.deployment.annotations.BuildProducer<io.quarkus.arc.deployment.AdditionalBeanBuildItem> additionalBeanBuildItemBuildProducer)
      We generate a class that contains as many CDI producer methods as there are JAX-RS Resources that use JAX-RS params. If for example there was a single such JAX-RS resource looking like: 
      
 @Path("/query")
 public class QueryParamResource {

         private final String queryParamValue;
         private final UriInfo uriInfo;

         public QueryParamResource(@QueryParam("p1") String headerValue, @Context UriInfo uriInfo) {
                this.headerValue = headerValue;
   }

   @GET
   public String get() {
            // DO something
   }
 }
      then the generated producer would look like this: 
      
  @Singleton
 public class ResourcesWithParamProducer {

    private String getHeaderParam(String name) {
      return (String)new HeaderParamExtractor(name, true).extractParameter(getContext());
    }

    private String getQueryParam(String name) {
      return (String)new QueryParamExtractor(name, true, false, null).extractParameter(getContext());
    }

    private String getPathParam(int index) {
      return (String)new PathParamExtractor(index, false, true).extractParameter(getContext());
    }

    private String getMatrixParam(String name) {
      return (String)new MatrixParamExtractor(name, true, false).extractParameter(getContext());
    }

    private String getCookieParam(String name) {
      return (String)new CookieParamExtractor(name, null).extractParameter(getContext());
    }

    @Produces
    @RequestScoped
    public QueryParamResource producer_QueryParamResource_somehash(UriInfo uriInfo) {
                return new QueryParamResource(getQueryParam("p1"), uriInfo);
    }

        private ResteasyReactiveRequestContext getContext() {
                return CurrentRequestManager.get();
    }
 }
