Core Resilience Features in Spring Framework 7
summary
Spring Framework 7 adds concrete resilience primitives: @Retryable (defaults to initial attempt plus a maximum of 3 retries), a programmatic RetryTemplate with retry policies, backoff multipliers, jitter and an overall timeout, and @ConcurrencyLimit that blocks callers by default (or fails fast) to cap concurrent invocations. Reactive return types translate to Reactor retry/backoff operators; sync task executors gain configurable concurrency limits and virtual thread support. Available since 7.0.6 and effectively replaces the old Spring Retry project.
