What is the role of @SpringBootApplication annotation?

@SpringBootApplication annotation can be used to enable those three features below.

• @EnableAutoConfiguration enable Spring Boot's auto-configuration mechanism.
• @ComponentScan enable @Component scan on the package where the application is located.
• @Configuration allow to register extra beans in the context or import additional configuration classes.

The @SpringBootApplication annotation is equivalent to using @Configuration, @EnableAutoConfiguration, and @ComponentScan with its default attributes.

package net.javapedia.springboot.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication // same as using @Configuration @EnableAutoConfiguration @ComponentScan
public class MyApplication {

	public static void main(String[] args) {
		SpringApplication.run(MyApplication.class, args);
	}

}
