Java based Configuration : 
The official Spring documentation refers to configuring your beans using a Java class annotated with @Configuration
and containing @Bean methods as 'Java Configuration'. This allows you to be absolutely free of all XML in your 
application (at least as far as Spring goes). This support was added in Spring 3.0, and has gotten more powerful.

Annotation based Configuration:
Starting from Spring 2.5 it became possible to configure the dependency injection using annotations. 
So instead of using XML to describe a bean wiring, you can move the bean configuration into the component
class itself by using annotations on the relevant class, method, or field declaration.
