In resteasy-jaxrs-3.0.5, you can retrieve a ResourceMethodInvoker representing the matched resource method from ContainerRequestContext.getProperty() inside a ContainerRequestFilter:

   import org.jboss.resteasy.core.ResourceMethodInvoker;

   public class MyRequestFilter implements ContainerRequestFilter
   {
       public void filter(ContainerRequestContext request) throws IOException
       {
            String propName = "org.jboss.resteasy.core.ResourceMethodInvoker";
            ResourceMethodInvoker invoker = (ResourceMethodInvoker)request.getProperty();
            invoker.getMethod().getParameterTypes()....
       }
   }
