spring-webclient

问题 I don't understand reactive webclient works.

问题 I am getting a NoClassDefFoundError on the line where I try to create WebClient instance using ' create '. Tried builder() but still the same thing.

问题 I am doing some testing with Spring WebClient. In the following codes, I have set the compress to true. However when I check the debug logs, I can see the "accept-encoding: gzip" header is added, but the body is not compressed. Any way to force compress on post request body? Thanks. HttpClient httpClient = HttpClient.create().compress(true).wiretap(true); WebClient webClient = WebClient.builder() .baseUrl("https://jsonplaceholder.typicode.com") .defaultHeader(HttpHeaders.CONTENT_TYPE,
