问题 It seems like it the Spring RestTemplate isn't able to stream a response directly to file without buffering it all in memory. What is the proper to achieve this using the newer Spring 5 WebClient ?

I see people have found a few workarounds/hacks to this issue with RestTemplate , but I am more interested in doing it the proper way with the WebClient

问题 I'm trying to add a conditional Retry for WebClient with Kotlin Coroutines + WebFlux.fn + reactor-addons: suspend fun ClientResponse.asResponse(): ServerResponse = status(statusCode()) .headers { headerConsumer -> headerConsumer.addAll(headers().asHttpHeaders()) } .body(bodyToMono(DataBuffer::class.java), DataBuffer::class.java) .retryWhen { Retry.onlyIf { ctx: RetryContext<Throwable> -> (ctx.exception() as? WebClientResponseException)?.statusCode in retryableErrorCodes } .exponentialBackoff

问题 How many concurrent requests can I send if the remote service if blocking? Means: what is the maxConnection pool limit that spring uses internally when using WebClient ? @Autowired private WebClient webClient; webClient.post().uri(url).syncBody(req).retrieve().bodyToMono(type); And moreover: how can I modify it? 回答1: Before reactor-netty 0.9.0.M4 version there wasn't limit by default because of "elastic" connection provider was used. This fix changed it to "fixed" connection provider with the
