How to match proxied service in log4j logger configuration?

I would like to set custom log level for Spring @Configuration bean. Proxy name is dynamically generated such as:

com.vegcatalog.app.config.CustomServletRequestListener$$EnhancerBySpringCGLIB$$7a65e8cd

Putting this line to log4j

logging.level.com.vegcatalog.app.config.CustomServletRequestListener = TRACE

does not help as the name is suffixed by Spring's Enhancer. I have other items in "config" package that should stay at default level, so this is not the one I want:

logging.level.com.vegcatalog.app.config = DEBUG

Is there any other solution than moving class to its own package just because lack of configuration options?

Thanks!
