如何让Spring sleuth在使用Feign builder时工作

Question

我正试图让spring slueth通过我们的系统提供追踪身份。

在检查其他服务的日志时，我注意到正在生成新的ID。

@Configuration
@RequiredArgsConstructor
public class OkHttpConfig {

  private final Properties properties;

  @Bean
  public OkHttpClient okHttpClient() {
    return new Builder()
        .connectTimeout(properties.getHttpTimeoutMillis(), TimeUnit.MILLISECONDS)
        .readTimeout(properties.getHttpTimeoutMillis(), TimeUnit.MILLISECONDS)
        .writeTimeout(properties.getHttpTimeoutMillis(), TimeUnit.MILLISECONDS)
        .connectionPool(new ConnectionPool(properties.getHttpPoolSize(),
            properties.getHttpKeepAliveMillis(), TimeUnit.MILLISECONDS))
        .build();
  }

@Configuration
public class HttpClientConfiguration {

  @Autowired
  private Properties properties;

  @Autowired
  private Client client;

  @Bean
  public SomeClient SomeClient(Client client, ObjectMapper objectMapper {
    return feignClient(properties.getUrl(), SomeClient.class, client,
            objectMapper);
  }

  public static <T> T feignClient(String baseUrl, Class<T> clientClass,
      Client client, ObjectMapper objectMapper) {
    return Feign.builder()
        .client(client)
        .decoder(new JacksonDecoder(objectMapper))
        .encoder(new JacksonEncoder(objectMapper))
        .target(clientClass, baseUrl);
  }

Unsatisfied dependency expressed through field 'client'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type 'feign.Client' available: 
expected at least 1 bean which qualifies as autowire candidate.Dependency annotations:

在聊天(https://chat.stackoverflow.com/rooms/188411/discussion-between-yk-47-and-marcin-grzejszczak)中，我们分析了当前的设置。它缺少了bean定义，最重要的是，它缺少了spring-cloud的开场白。
