One is the use of CGLib based class proxies for Spring's AOP. It can also be done via Java's dynamic proxies but default is CGLib. So don't be surprised if you see CGLib in your stack trace.
Other is the use of AOP for DI. Yes, it's all AOP everywhere without you knowing it. It's cool to know that your code is AOP based even if you are only using Spring for DI purposes.
