What does @SpringBootApplication comprise of?

It is a convenience annotation that combines three key annotations:

1. @SpringBootConfiguration: Tags the class as a source of bean definitions for the application context.
2. @EnableAutoConfiguration: Tells Spring Boot to start adding beans based on classpath settings, other beans, and various property settings.
3. @ComponentScan: Tells Spring to look for other components, configurations, and services in the package, allowing it to find and register beans.
