@Bean inside class with @Configuration and without it

Question

There is a @Bean annotation in Spring 3.0. It allows to define a Spring bean directly in a Java code. While browsing Spring reference I found two different ways

Answer 1

@Bean [instance method] inside @Component - One method with @Bean instance call other method @Bean instance , then it would be simple java semantics call i.e. Object won't returned by Spring container , It would be normal return from java instance factory method,because Component class don't extends CGLIB.

@Bean [instance method] inside @Configuration - In this case , spring container would be returning reference to exisiting object. It won't be normal java sematic call.

@Bean on static method inside Configuration & Component Class - In this case , @Bean method would never be intercepted by the container neither in Configuration class nor in Component Sterotype class.
