Answer 1

I found a blog here that clearly explains how AOP,Caching & Transaction works using runtime proxy classes.

When not coding to interface (quoting from the blog's section 'What if the bean class does not implement any interface?'):-

By default, if your bean does not implement an interface, Spring uses technical inheritance: at startup time, a new class is created. It inherits from your bean class and adds behavior in the child methods. In order to generate such proxies, Spring uses a third party library called cglib.
