spring webclient: retry with backoff on specific error

Question

i\'d like to retry the request 3 times after waiting 10sec when response is 5xx. but i don\'t see a method that I can use. On object

WebClient.builder()
             


        

Answer 1

the retryWhen with Retry.anyOf and Retry.onlyIf are deprecated I assume. I found this approach useful, and it allows us to process and throw a User defined exception.

for example :

retryWhen(Retry.backoff(3, Duration.of(2, ChronoUnit.SECONDS))
                        .filter(error -> error instanceof UserDefinedException/AnyOtherException)
                        .onRetryExhaustedThrow((retryBackoffSpec, retrySignal) ->
                                new UserDefinedException(retrySignal.failure().getMessage())))
