SpringBoot之使用Feign实现微服务间的交互

server:
  port: 7102 # 端口
spring:
  application:
    name: order   # 注册到Eureka Server显示的应用名称
 
eureka:
  client:
    serviceUrl:
      defaultZone: http://admin:admin135@localhost:7200/eureka/
  instance:
    prefer-ip-address: true  #将自己的IP注册到Eureka Server
    instance-id: ${spring.application.name}:${spring.cloud.client.ip-address}:${server.port} #:${random.long(1,100)}
