常见错误

loadbalancer开启后报错

开启下面开关
spring:
cloud:
loadbalancer:
ribbon:
enabled: true
后，控制台报错

Parameter 0 of method loadBalancerWebClientBuilderBeanPostProcessor in org.springframework.cloud.client.loadbalancer.reactive.LoadBalancerBeanPostProcessorAutoConfiguration required a bean of type 'org.springframework.cloud.client.loadbalancer.reactive.DeferringLoadBalancerExchangeFilterFunction' that could not be found.

The following candidates were found but could not be injected:
	- Bean method 'deferringLoadBalancerExchangeFilterFunction' in 'LoadBalancerBeanPostProcessorAutoConfiguration.ReactiveLoadBalancerConfig' not loaded because @ConditionalOnBean (types: org.springframework.cloud.client.loadbalancer.LoadBalancerClient; SearchStrategy: all) did not find any beans of type org.springframework.cloud.client.loadbalancer.LoadBalancerClient
	- Bean method 'reactorDeferringLoadBalancerExchangeFilterFunction' in 'LoadBalancerBeanPostProcessorAutoConfiguration.ReactorDeferringLoadBalancerFilterConfig' not loaded because AnyNestedCondition 0 matched 2 did not; NestedCondition on OnNoRibbonDefaultCondition.RibbonLoadBalancerNotPresent @ConditionalOnMissingClass found unwanted class 'org.springframework.cloud.netflix.ribbon.RibbonLoadBalancerClient'; NestedCondition on OnNoRibbonDefaultCondition.RibbonNotEnabled @ConditionalOnProperty (spring.cloud.loadbalancer.ribbon.enabled=false) found different value in property 'spring.cloud.loadbalancer.ribbon.enabled'


Action:

Consider revisiting the entries above or defining a bean of type 'org.springframework.cloud.client.loadbalancer.reactive.DeferringLoadBalancerExchangeFilterFunction' in your configuration.

解决方法

将原来的

		<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-loadbalancer</artifactId>
        </dependency>

替换为

 		<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
        </dependency>
