关键错误：

WARN  com.netflix.discovery.InstanceInfoReplicator - Ignoring onDemand update due to rate limiter

解决方案：
引入jar包

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

yml配置

eureka:
  client:
    healthcheck:
      enabled: true  # 当使用nacos配置中心时,必须设置为true,不然nacos动态修改配置时会出现eureka服务实例下线的问题

#监控配置
management:
  health:
    defaults:
      enabled: false #禁用所有组件健康检查

springcloud 和配置中心一起使用时踩到的一个坑
使用refreshScope.refresh导致Eureka服务下线
Spring Cloud Eureka服务注册
