The @SpringBootApplication annotation is a cornerstone of any Spring Boot application, simplifying setup and minimizing boilerplate code, while combining key functionalities.
As a composite annotation, @SpringBootApplication includes @Configuration for bean definitions, @EnableAutoConfiguration for automatic setup, and @ComponentScan for locating components.
By using @SpringBootApplication, developers benefit from automatic configuration based on classpath dependencies, which eliminates much of the manual setup traditionally required.
The primary role of @SpringBootApplication is to designate the main class and bootstrap the application, thereby helping in application context initialization and component scanning.
