解决java.lang.ClassNotFoundException: org.springframework.cloud.client.loadbalancer.LoadBalancedRetryFactory

使用Spring Cloud Feign时遇到如下Class Not Found Error

Caused by: java.lang.NoClassDefFoundError: org/springframework/cloud/client/loadbalancer/LoadBalancedRetryFactory

我使用的软件版本信息如下：

springCloudVersion = 'Finchley.M2'
springBootVersion = '2.0.0.M3'

解决办法

把openfeign的版本从原来默认的springCloudVersion改为springBootVersion，也就是2.0.0.M3

// Feign
compile("org.springframework.cloud:spring-cloud-starter-openfeign:${springBootVersion}")
