spring - 使用Spring Webflux WebClient进行服务发现

可以在Spring Webflux WebClient中使用Ribbon和Eureka服务发现吗？

我尝试了这段代码，但是在集成测试中遇到了错误。

Reactor.core.Exceptions $ ErrorCallbackNotImplemented:java.lang.IllegalArgumentException:URI不是绝对的:/auth-service/auth-service/validate-manager-client-access

@Bean
  @LoadBalanced
  public WebClient loadBalancedWebClient() {
    return WebClient.create(baseURL);
  }

  @Override
  public Mono<Boolean> validateManagerClientAccess(Mono<LoginDTO> loginDTOMono) {
    return webClient
        .post()
        .uri(validateManagerURL)
        .body(loginDTOMono, LoginDTO.class)
        .retrieve()
        .bodyToMono(Boolean.class);
  }

# Remote Services Configuration
remote:
  auth-service:
    service-id: auth-service
    path:
      validate-manager-client-access: /auth-service/validate-manager-client-access

最佳答案

看着我自己... Piotr Minkowski在这里很好地回答了这个问题...

为了方便起见，我将最相关的部分发布到此答案。

创建负载平衡的Web客户端构建器

 @Bean
 @LoadBalanced
 public WebClient.Builder loadBalancedWebClientBuilder() {
     return WebClient.builder();
 }

然后可以像

@Autowired
private WebClient.Builder webClientBuilder;
@GetMapping("/{id}/with-accounts")
public Mono findByIdWithAccounts(@PathVariable("id") String id) {
    LOGGER.info("findByIdWithAccounts: id={}", id);
    Flux accounts= webClientBuilder.build().get().uri("http://accountservice/customer/{customer}", id).retrieve().bodyToFlux(Account.class);
return accounts
      .collectList()
      .map(a -> new Customer(a))
      .mergeWith(repository.findById(id))
      .collectList()
      .map(CustomerMapper::map);
}
