问题 I'm using WebClient (SpringBoot 2.0.2.RELEASE) to send a POST with SOAP request, but it is missing " Content-Length " header required by the legacy API. Is it possible to configure WebClient to include " Content-Length " header? There is an Spring Framework Issue resolved and introduced for EncoderHttpMessageWriter in SpringBoot 2.0.1, but it seems not to work for JAXB. I tried to use BodyInserters : webClient.post().body(BodyInserters.fromObject(request)).exchange(); and syncBody : webClient

问题 I use SpringBoot and reactive programming with Webflux. I want to repeat some calling of my endpoint till data will be available (something will be returned). I want to call commandControllerApi.findById until displayCommand will be returned with status == SUCCESS . How to tell Webflux that this part of my chain should be called for example 5 times because the data in my database should apper after 5-10 seconds... I think the current code causes calling the whole chain again and not only the

问题 I am developing a Spring WebFlux application and I have a web adapter that I use to call the external api methods that I use. One of the apis has a paginated result using a link header with a rel="next". I need to call this api until this next link does not exist but I am unsure how to achieve this. Below is the basic call that I am currently using: public Flux<ItemDto> getAllItems(){ return webClient.get() //The headers and base url for the api are defined in the constructor .uri("/api/items

问题 I'm not able to open more than 10 connections with spring-webflux and r2dbc (with r2dbc-pool driver 0.8.0.M8 ). My config looks like: @Configuration public class PostgresConfig extends AbstractR2dbcConfiguration { @Override @Bean public ConnectionFactory connectionFactory() { ConnectionFactory connectionFactory = ConnectionFactories.get(ConnectionFactoryOptions.builder() .option(DRIVER, "pool") .option(PROTOCOL, "postgresql") .option(HOST, host) .option(USER, user) .option(PASSWORD, password)

问题 I'm trying to use the Spring Reactive WebClient to upload a file to a spring controller. The controller is really simple and looks like this: @PostMapping(value = "/upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE) public ResponseEntity<String> uploadFile( @RequestParam("multipartFile") MultipartFile multipartFile, @RequestParam Map<String, Object> entityRequest ) { entityRequest.entrySet().forEach(System.out::println); System.out.println(multipartFile); return ResponseEntity.ok("OK");

问题 Is it possible to do something like the code below? I have one service that makes an API call and another one which returns a stream of values. I need to modify every value by the value returned by the API call. return Flux.zip( someMono.get(), someFlux.Get(), (d, t) -> { //HERE D IS ALWAYS THE SAME AND T IS EVERY NEW FLUX VALUE }); I've tried with .repeat() for the Mono and it works, but it's calling the method every time there's a new Flux value and it's a API call, so it's not good. Is it
