篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了我装管理软件,用的移动宽带,不给公网IP怎么解决相关的知识,希望对你有一定的参考价值。
参考技术A 租台服务器,把管理软件部署上去,就可以访问了,租服务器会送一个ipjava 动态修改阿里云域名解析,用于解决家用宽带公网ip经常变动问题
需要有java、maven、springboot、阿里云域名使用经验、以及拥有一个域名

maven 打成包过后,直接在内网 java -jar update-domain-ip.jar 即可,只要外网ip变动了就会改变,这个3分钟就扫描一次,对于及时性要高一些的,可以提高扫描的频率
外网都需要通过域名访问,ip变了也无所谓,反正你只关心域名就行了
