如何使用WebClient执行同步请求？

Question

Spring documentation states that we have to switch from RestTemplate to WebClient even if we want to execute synchronous http call.

For now I have following code:

  Mono<ResponseEntity<PdResponseDto>> responseEntityMono = webClient.post()
                .bodyValue(myDto)
                .retrieve()
                .toEntity(MyDto.class);
        responseEntityMono.subscribe(resp -> log.info("Response is {}", resp));
   //I have to return response here
   // return resp;

Sure I could use CountdownLatch here but it looks like API misusing.

How could I execute synchronous request?

Answer 1

It works:

webClient.post()
         .bodyValue(myDto)
         .retrieve()
         .toEntity(MyDto.class)
         .block(); // <-- This line makes trick

Answer 2

!!!Attention!!!

For a fresh version of webflux please use:

webClient.post()
         .bodyValue(myDto)
         .retrieve()
         .toEntity(MyDto.class)
         .toFuture()
         .get();
