Companion code for "Spring Framework 7's Built-in Resilience: @Retryable, @ConcurrencyLimit, and What's Left for Resilience4j". Every retry counted by recording real invocations: defaults, backoff and jitter, timeout, reactive and CompletableFuture returns, the concurrency limit's BLOCK and REJECT policies, retries around transactions, composition with Resilience4j 2.4.0, and the annotation API across 7.0.0-7.0.9.

Reflection over Retryable.class.getDeclaredMethods() on 7.0.9
(ApiSurfaceTest):

maxRetries |
3 - retries after the first call |

@ConcurrencyLimit has no usable default limit (Integer.MIN_VALUE means "not set") and
policy = BLOCK. @EnableResilientMethods has proxyTargetClass = false and
order = Integer.MAX_VALUE - 1.
It moved during 7.0.x
api-surface.txt, per release:
| Added in | What |
|---|---|
| 7.0.0 | @Retryable (no timeout), @ConcurrencyLimit (no policy), RetryTemplate, RetryPolicy |
| 7.0.2 | @Retryable.timeout/timeoutString, RetryPolicy.Builder.timeout(..), RetryListener.onRetryPolicyTimeout and onRetryableExecution |
| 7.0.3 | @ConcurrencyLimit.policy with ThrottlePolicy.BLOCK / REJECT |
Release dates from the Maven Central Last-Modified headers: 7.0.0 on 13 Nov 2025, 7.0.2 on
11 Dec 2025, 7.0.3 on 15 Jan 2026. Articles written against the 7.0 GA - including the Spring reference page at the time
this was written, which does not mention timeout or policy - describe a smaller API than the
one you have.
