springcloud feign报错：Load balancer does not have available server for client

在项目使用feign拉取其他项目的服务时会报错Load balancer does not have available server for client

修改配置文件 添加fetch-registry: true

# eureka config
eureka:
  instance:
    prefer-ip-address: true
  client:
    serviceUrl:
      defaultZone: http://localhost:8888/eureka/
      ##如果不加就不会去注册中心拉取服务，导致无法拉取服务
      fetch-registry: true
