解决Eureka启动过程报错：java.net.ConnectException: Connection refused

解决方法：
在配置文件添加以下配置

eureka:
  client:
    fetch-registry: false #不检索服务
    register-with-eureka: false #不向注册中心注册自己
    service-url:
      defaultZone: http://localhost:${server.port}/eureka
  server:
    enable-self-preservation: false # 关闭自我保护
    eviction-interval-timer-in-ms: 5000 # 每隔5秒进行一次服务列表清理
