This application has no explicit mapping for /error, so you are seeing this as a fallback.

对于这个错误，我试了很多方法，工程也重建了，就是不解决，我的其他服务都能注册上，唯独就这个注册不上，一个一个地方的排查，最后问题竟然是配置文件application.yaml中spring.application.name上

这是出错的，studentserver，但是当我给他改成别的就可以正常注册了，比如中间加下横线 

所以我猜测可能是server的"s"字母和student(s)冲突了，后面我把student改成students也是正常运行，nacos上也是有服务信息。

这是我遇到的问题和解决办法，希望能对你们有帮助，有大佬知道这是怎么原理也可以评论私信告诉我 。
