Resilience and Retry (Boot 3)

Boot 3 does not have Spring Framework 7 core resilience annotations. Choose Spring Retry for simple imperative retry or Resilience4j when you also need circuit breakers, rate limiting, or bulkheads. Keep the dependency and configuration explicit.

@Configuration
@EnableRetry
class RetryConfig { }

@Service
class PaymentClient {
    @Retryable(
        retryFor = ConnectException.class,
        maxAttempts = 4,
        backoff = @Backoff(delay = 200, multiplier = 2.0, maxDelay = 2000))
    PaymentResult charge(ChargeRequest request) { ... }
