关于nacos无限刷日志的问题解决过程

情况1：
https://www.jianshu.com/p/37b9719c1191
这一篇是在Linux下启动的Nacos，然后，解决办法是，给Nacos服务指定固定IP
但是，对我的情况无效

情况2：

说是Nacos版本的bug，于是，升级nacos服务即可
我也升级了，但是无效

我的情况：
我在springboot配置文件中，设置了Nacos连接的账号密码

  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
        namespace: ${NACOS_SPACE:public}
        username: ${NACOS_USERNAME:nacos}
        password: ${NACOS_PASSWORD:nacos}

所以，导致不停的刷取配置
控制台信息如下：

于是，我去除账号密码的设置，就解决消除了这个情况
但是，这不是最终办法
应该保证在设置密码和不设置密码的两种情况下，都不会刷配置的情况。
有待进一步解决。
