Spring Webflux : Webclient : Get body on error

Question

I am using the webclient from spring webflux, like this :

WebClient.create()
            .post()
            .uri(url)
            .syncBody(body)
            .a         


        

Answer 1

I do something like this:

Mono responseMono = requestSpec.exchange()
            .doOnNext(response -> {
                HttpStatus httpStatus = response.statusCode();
                if (httpStatus.is4xxClientError() || httpStatus.is5xxServerError()) {
                    throw new WebClientException(
                            "ClientResponse has erroneous status code: " + httpStatus.value() +
                                    " " + httpStatus.getReasonPhrase());
                }
            });

and then:

responseMono.subscribe(v -> { }, ex -> processError(ex));
