• Feign报错Caused by: com.netflix.client.ClientException: Load balancer does not have available server f

• 1.引入Eureka依赖

• 2.@AuthorizedFeignClient注解中name写错

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

ribbon:
  eureka:
    enabled: true

springCloud com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect

或者com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server

原因如下：

在默认设置下，Eureka服务注册中心也会将自己作为客户端来尝试注册它自己，所以我们需要禁用它的客户端注册行为。

禁止方式如下：在application.properties配置文件中增加以下内容

eureka.client.register-with-eureka=false

eureka.client.fetch-registry=false
