3.1 修改配置

在无Eureka 环境下如何运行Spring Cloud RIbbon 提供的负载均衡？修改一下application.yml配置

ribbon:
  eureka:
    enabled: false #禁用eurake
# 禁用 Eureka 后手动配置服务地址
fw-cloud-ribbon-server: #服务名称
  ribbon:
    listOfServers: localhost:8773,localhost:8774

这里需要将Eureka设置为false,就是不启用从Eureka获取服务实例，但是需要将已经启动的服务端实例的地址设置在调用服务的后面，规则如下

服务名称(spring.application.name):
    ribbon:
        listOfServers: ip:port,ip:port

3.2 重新启动

通过postman 重新请求localhost:8771/user/1

并且控制台会把配置的实例地址输出来
