spring webclient执行异常：DeferringLoadBalancerExchangeFilterFunction non qualifying bean

[undefined]

我已经用spring webflex创建了spring boot项目。我的想法是学习spring webclient和相关的东西。在应用程序启动时，我得到了以下错误:

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等依赖项。错误只是给出了DeferrringLoadBalancerExchangeFilterFunction不可用的信息，我已经尝试在配置类中使用@Bean注入它。但错误仍然存在。请指教

请注意，在我的代码中，我使用了feign client以及web client。不知道这是否有影响
