使用 spring webflux WebClient 发现服务 [英] Service discovery with spring webflux WebClient

问题描述

是否可以将 Ribbon 和 Eureka 服务发现与 spring webflux webclient 一起使用?

Is it possible to use Ribbon and Eureka service discovery with spring webflux webclient?

我尝试了此代码，但在集成测试期间出错.

I tried this code but getting an error during integration test.

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

reactor.core.Exceptions$ErrorCallbackNotImplemented: java.lang.IllegalArgumentException: URI is not absolute: /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

为方便起见，我将发布与此答案最相关的部分.

I will post the most relevant sections to this answer for convenience.

创建负载均衡的网络客户端构建器

Create the load balanced web client builder

 @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);
}
