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.

7. Migrating from spring-retry
← 6. What is left for Resilience4j · Index
The spring-retry README now says the project "is no longer maintained as an open-source project" and "has been superseded by Spring Framework 7". Its last release on Maven Central is 2.0.13.
| spring-retry | Spring Framework 7 | Watch out |
|---|---|---|
@EnableRetry |
@EnableResilientMethods |
|
@Retryable(maxAttempts = 3) |
@Retryable(maxRetries = 2) |
attempts vs retries - maxRetries = 3 is one call more |
@Retryable(retryFor = X.class) |
@Retryable(includes = X.class) (or value) |
causes are matched too |
@Retryable(noRetryFor = X.class) |
@Retryable(excludes = X.class) |
|
@Backoff(delay, multiplier, maxDelay) |
delay, multiplier, maxDelay attributes |
default delay is 1000 ms in both |
@Backoff(random = true) |
jitter |
jitter only adds delay (chapter 3) |
@Recover |
none - catch the exception in the caller | declined upstream |
RetryTemplate.builder() |
new RetryTemplate(RetryPolicy.builder()...build()) |
execute throws RetryException; invoke throws the original |
stateful retry / RetryContext |
none |
Keep spring-retry on the classpath only as long as something still uses @Recover or stateful
retry. Both libraries define an annotation named Retryable - check the import on every one.
