Accepted Answer

Annotations in Spring Boot simplify configuration and enhance code readability, enabling easier development and management of applications.

@SpringBootApplication: Combines @Configuration, @EnableAutoConfiguration, and @ComponentScan for easy setup.
@RestController: Indicates that a class is a controller where every method returns a domain object instead of a view.
@Autowired: Automatically injects dependencies into Spring beans, reducing boilerplate code.
@RequestMapping: Maps HTTP requests to specific handler methods in controllers.
@Entity: Marks a class as a JPA entity, allowing it to be mapped to a database table.
