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 got the error body by doing like this:

webClient
...
.retrieve()    
.onStatus(HttpStatus::isError, response -> response.bodyToMono(String.class) // error body as String or other class
                                                   .flatMap(error -> Mono.error(new RuntimeException(error)))) // throw a functional exception
.bodyToMono(MyResponseType.class)
.block();
