How do you add Spring Retry to a Spring Boot project?

To add Spring Retry to a Spring Boot project, you include the spring-retry dependency in your build file and enable retry support with an annotation on your configuration class.

Maven dependency:

<dependency>
    <groupId>org.springframework.retry</groupId>
    <artifactId>spring-retry</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
</dependency>

The spring-aspects dependency is required because Spring Retry uses AOP proxies under the hood when annotation-based retrying is enabled.

Enable retry in configuration:

@Configuration
@EnableRetry
public class AppConfig {
}

Once @EnableRetry is placed on a configuration class, Spring scans for @Retryable and @Recover annotations in your beans and wraps them automatically. Without this annotation, the retry annotations are silently ignored.

In Spring Boot, it is common to place @EnableRetry directly on the main application class alongside @SpringBootApplication for simplicity.
