Annotations

OAnnotations are metadata markers placed on classes, methods, or fields that tell Spring how to treat a piece of code, such as @Component to register a bean or @Autowired to inject a dependency. Spring Boot relies heavily on annotations to reduce configuration files, using ones like @SpringBootApplication to bootstrap an entire application with sensible defaults. They are processed at startup to wire beans, map requests, and configure behavior without extra boilerplate.
