A Spring IoC container manages one or more beans. These beans are created with the configuration metadata that you supply to the container (for example, in the form of XML <bean/> definitions).
@Bean is a method-level annotation and a direct analog of the XML <bean/> element.

Therefore, the three ways to implement this are:
