Question

Accepted Answer

SpringBootApplication is a combination of three annotations in Spring Boot.

SpringBootApplication is a meta-annotation that combines @Configuration, @EnableAutoConfiguration, and @ComponentScan annotations.
@Configuration annotation indicates that the class is a source of bean definitions.
@EnableAutoConfiguration annotation enables Spring Boot to automatically configure the application based on the dependencies added to the classpath.
@ComponentScan annotation tells Spring to scan and detect other Spring components in the package.
This annotation is used to simplify the configuration of Spring Boot applications.
Example: @SpringBootApplication public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }
