Spring FaignClient:如何配置类似Ribbon的负载平衡器

我使用的是SpringFeignClient,必须支持SpringRibbon提供的负载平衡。

@FeignClient(name = "testClient", url = "${test.url}", configuration = TestConfig.class)
@RequestMapping(produces = MediaType.APPLICATION_JSON_VALUE, consumes = 
 MediaType.APPLICATION_JSON_VALUE)
 public interface TestClient {
 }

public class TestConfig{
 @Bean
 public Client feignClient() {
    return new ApacheHttpClient(getHttpClient());
  }
}
