Spring Boot Retry Pitfall: Timeout ≠ Failure — Idempotency & Concurrency Fixes

The article explains why naive retries after timeouts cause duplicate orders in Spring Boot, demonstrating how to properly classify retryable exceptions, implement idempotency with stable request IDs, handle non-idempotent third-party APIs via query-before-retry, add concurrency limits with @ConcurrencyLimit, and separate concerns into Service, Gateway, and Client layers using Spring Framework 7's @Retryable.

Spring Framework 7 Retry & ConcurrencyLimit: Avoiding the Traffic Amplifier Trap

The author migrates from hand-written retry code and Spring Retry to Spring Framework 7's built-in @Retryable and @ConcurrencyLimit, discovering that retry logic can amplify downstream traffic under virtual threads, and shares lessons on selective exception handling, jitter, idempotency for write operations, and the difference between local concurrency limits and distributed rate limiting.

Why I Dropped @FeignClient After Years of Use: Spring Boot’s Built‑In HTTP Service Client

The author refactors an old Spring Cloud project by removing Feign, replacing @FeignClient with Spring Boot 4.x’s native @HttpExchange and @ImportHttpServices, and demonstrates that Spring’s built‑in HTTP Service Client provides the same declarative convenience with less boilerplate, while still supporting custom configuration, error handling, and reactive use cases.
