Practice 4 Spring

Annotations.

@SpringBootApplication.

A meta-annotation that combines three core Spring annotations - @Configuration - Marks the class as a source of bean definitions.

@EnableAutoConfiguration - Enables Spring Boot’s auto-configuration mechanism based on classpath settings, beans, and property configurations.

@ComponentScan - Enables component scanning so that Spring can discover and register beans in the application context.

🔍 Effect - It bootstraps the entire Spring Boot application.

@EnableRetry

Enables Spring Retry functionality.

🔍 Effect:

Allows methods annotated with @Retryable to be retried automatically on failure (e.g., transient network issues).

You can configure retry attempts, backoff policies, and exception types.

🧠 Use case: Retrying failed API calls, database operations, or message consumption in a resilient way.
