【问题描述】：
我已经使用 Spring WebFlux 创建了 Spring Boot 项目。想法是学习 Spring WebClient 和相关的东西。在应用程序开始时，我得到以下错误
Error creating bean with name 'loadBalancerWebClientBuilderBeanPostProcessor' defined in class path resource [org/springframework/cloud/client/loadbalancer/reactive/LoadBalancerBeanPostProcessorAutoConfiguration.class]:
Unsatisfied dependency expressed through method 'loadBalancerWebClientBuilderBeanPostProcessor' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException:
No qualifying bean of type 'org.springframework.cloud.client.loadbalancer.reactive.DeferringLoadBalancerExchangeFilterFunction<?>' available: expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: {}
我的 maven 依赖项中有 spring-cloud-dependencies/spring-boot-starter*/spring-cloud-context 之类的依赖项。仅提供 DeferrringLoadBalancerExchangeFilterFunction 不可用的信息时出错，我尝试在我的配置类中使用 @Bean 注入它。但错误仍然存在。请指教
在 pom.xml 中发布依赖项

请注意，我在代码中使用了 feign 客户端和 Web 客户端。不知道有没有影响
【问题讨论】：
-
请不要描述您的代码，并努力发布您的 pom 和您的代码。投票结束。
-
尝试将
spring-cloud-starter-loadbalancer添加到您的 pom.xml 中。如果这没有帮助，请发布您的整个 pom。 -
@OlgaMaciaszek - 我已经尝试过了，但仍然是同样的例外。只有当我认为我有 webflex 和 fiegn 客户端组合时才会发生这种情况
-
@Toerktumlare - 添加了 pom。
-
请删除明确添加的 spring cloud feign 版本并使用 bom (
spring-cloud-starter-openfeign) 附带的依赖项 - 如果有帮助，请告诉我。如果没有，请粘贴整个 pom 文件。
