Spring cloud Spring Cloud LoadBalancerClient-Hoxton SR8-抛出错误

以前我们使用的是SpringCloudFinchley.M9版本。我们使用LoadBalancerClient，如下所示

'''import java.net.URI;
import java.util.Objects;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.client.ServiceInstance;
import org.springframework.cloud.client.loadbalancer.LoadBalancerClient;
import org.springframework.stereotype.Component;

@Component
public class UriResolver {

    private static final Logger LOGGER = LoggerFactory.getLogger(UriResolver.class);

    private LoadBalancerClient loadBalancerClient;

    @Autowired
    public UriResolver(LoadBalancerClient loadBalancerClient) {
        this.loadBalancerClient = loadBalancerClient;
    }

    public URI getBaseUri(String vendorName) {
        ServiceInstance instance = loadBalancerClient.choose(vendorName);
        URI uri = null;
        if (!Objects.isNull(instance)) {
            uri = instance.getUri();
            LOGGER.debug("LoadBalancer Instance specific URI: " + instance.getUri());
            LOGGER.debug("LoadBalancer Instance specific ServiceId: " + instance.getServiceId());
            LOGGER.debug("LoadBalancer Instance specific Host: " + instance.getHost());
        }
        return uri;
    }

}'''

现在我们已经将spring云版本升级到Hoxton.SR8。启动spring boot应用程序时出现以下错误

---

“RibbonAutoConfiguration”中的Bean方法“loadBalancerClient”未加载，因为AllNestedConditions 2与2不匹配；RibbonAutoConfiguration.RibbonClassesConditions.RibbonPresent@ConditionalOnClass上的NestedCondition未找到所需的类“com.netflix.ribbon.ribbon”；RibbonAutoConfiguration.RibbonClassesConditions.AsyncRestTemplatePresent@ConditionalOnClass上的NestedCondition找到了必需的类“org.springframework.web.client.AsyncRestTemplate”；RibbonAutoConfiguration.RibbonClassesConditions.RestTemplatePresent@ConditionalOnClass上的NestedCondition找到了必需的类“org.springframework.web.client.RestTemplate”；RibbonAutoConfiguration.RibbonClassesConditions.IClientPresent@ConditionalOnClass上的NestedCondition未找到所需的类“com.netflix.client.IClient”

是否添加了功能区启动程序？我没有功能区启动程序。当我使用Finchley.M9时，我也没有ribbon启动器。当我升级到Hoxton.SR8时，是否必须添加ribbon starter？在添加spring cloud starter ribbon之后，它就起作用了。谢谢，斯宾塞·吉布
