The @Configuration annotation in Spring is used to indicate that a class declares one or more @Bean methods, enabling the Spring container to generate bean definitions.
Annotating a class with @Configuration tells Spring to treat it as a source of bean definitions, scanning for @Bean methods and registering their return types.
The @Bean methods within a @Configuration class are essential for defining the managed objects, with Spring ensuring that each instance created is a singleton by default.
Using @Configuration helps organize a Spring application into manageable components, enhancing modularity and maintainability of the code by dedicating classes for bean definitions.
