Feign client and Spring retry

You can add a Retryer in the FeignClientConfig

@Configuration
public class FeignClientConfig {

    @Bean
    public Retryer retryer() {
        return new Custom();
    }

}

class Custom implements Retryer {

    private final int maxAttempts;
    private final long backoff;
    int attempt;

    public Custom() {
        this(2000, 3);
    }

    public Custom(long backoff, int maxAttempts) {
        this.backoff = backoff;
        this.maxAttempts = maxAttempts;
        this.attempt = 1;
    }

    public void continueOrPropagate(RetryableException e) {
        if (attempt++ >= maxAttempts) {
            throw e;
        }

        try {
            Thread.sleep(backoff);
        } catch (InterruptedException ignored) {
            Thread.currentThread().interrupt();
        }
    }

    @Override
    public Retryer clone() {
        return new Custom(backoff, maxAttempts);
    }
}

Updated with sample Retryer example config based on the Retryer.Default.

If you are using ribbon you can set properties, you can use below properties for retry:

myapp.ribbon.MaxAutoRetries=5
myapp.ribbon.MaxAutoRetriesNextServer=5
myapp.ribbon.OkToRetryOnAllOperations=true

Note: "myapp" is your service id.
