Note: spring beans we can configure in 3 ways

1) xml based configuration file

 Configure <beans> inside beans.xml file

 

2) annotation-based configuration

Configure <context:annotation-config/> inside beans.xml file and use annotations inside Java class. 

3) Java based configuration

Configurations happen in Java file without xml file.

with the help of annotations like @configuration, @component, @service, @controller.. etc.!
