Explain @SpringBootApplication, @Configuration and @ComponentScan annotations

Comment

The @SpringBootApplication annotation indicates a configuration class that declares one or more @Bean methods and also triggers auto-configuration and component scanning. 
This is a convenience annotation that is equivalent to declaring below three annotations:
@Configuration, @EnableAutoConfiguration, and @ComponentScan.

@Configuration annotation is used to create a Java-based Spring configuration class that contains @Bean definition methods.
So Spring container can process the class and generate Spring Beans to be used in the application.
The @ComponentScan annotation is used with the @Configuration annotation to tell Spring the packages to scan for annotated components.
