Circuit breaker: evaluate response as a failure

Hi,

I was checking the options for Circuit Breaker: https://resilience4j.readme.io/docs/circuitbreaker

But I didn´t see the possibility to evaluate a successful response as a failure. This possibility is available for another behaviour Retry: https://resilience4j.readme.io/docs/retry

retryOnResultPredicate
result -> false
Configures a Predicate which evaluates if a result should be retried. The Predicate must return true, if the result should be retried, otherwise it must return false.

Do you think that it is possible to add something similar in this behaviour?

Many thanks in advance.

We created a SupplierUtils which helps you in situations where you can’t modify the client code.

Supplier<HttpResponse> supplier = () -> httpClient.doRemoteCall();
Supplier<HttpResponse> supplierWithResultHandling = SupplierUtils.andThen(supplier, result -> {
    if (result.getStatusCode() == 400) {
       throw new HttpClientServerException();
    } else if (result.getStatusCode() == 500) {
       throw new HttpServerException();
    }
    return result;
});
HttpResponse httpResponse = circuitBreaker
  .executeSupplier(supplierWithResultHandling);

Applied the solution and the usage is easy.
