One of the most important annotations in spring is @Configuration annotation which indicates that the class has @Bean definition methods. So Spring container can process the class and generate Spring Beans to be used in the application. This annotation is part of the spring core framework.

https://docs.spring.io › spring-boot › reference › features › developing-auto-configuration.html

Spring Boot uses an annotation processor to collect the conditions on auto-configurations in a metadata file (META-INF/spring-autoconfigure-metadata.properties). If that file is present, it is used to eagerly filter auto-configurations that do not match, which will improve startup time.

Simply put, the Spring Boot auto-configuration helps us automatically configure a Spring application based on the dependencies that are present on the classpath. This can make development faster and easier by eliminating the need to define certain beans included in the auto-configuration classes.

The @SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration and @ComponentScan with their default attributes: [...] where the @ComponentScan javadoc states. If specific packages are not defined, scanning will occur from the package of the class that declares this annotation.
