How can I implement logging in the Spring Retry library?

You can implement logging in the Spring Retry library by using a logging framework like SLF4J. You can configure it to log retry attempts and failures.

Can you show me a code example?

Sure! Here's a simple example:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.retry.annotation.Backoff;
import org.springframework.retry.annotation.EnableRetry;
import org.springframework.retry.annotation.Retryable;
import org.springframework.stereotype.Service;

@Service
@EnableRetry
public class MyService {
    private static final Logger logger = LoggerFactory.getLogger(MyService.class);

    @Retryable(value = { MyException.class }, maxAttempts = 3, backoff = @Backoff(delay = 2000))
    public void myMethod() {
        logger.info("Attempting to execute myMethod...");
        // Your logic here
    }
}

This will log each attempt to execute myMethod.

What if I want to log the exceptions as well?

You can use an @Recover method to log exceptions. Here's how:

@Recover
public void recover(MyException e) {
    logger.error("Failed after retries: " + e.getMessage());
}

This method will be called when all retry attempts fail.
