Localhost or 127.0.0.1 are local unless you again ali directly open the browser on the server, otherwise you have to enter the server address,

I mean, SpringBoot jars and mysql is running on the server in the same ali cloud, it should be the same environment, so yml file inside the database link fill localhost or 127.0.0.1, program should be able to connect on mysql, but the problem is to fill up public IP to connect

Localhost is pointing in the direction you are using PC itself, if you use the PC request localhost will point you request of PC, so the localhost is variable, 127.0.0.1 is also in the same way, so of course you use other PC request localhost will automatically become your PC's IP, this request will fail, localhost can't literally,
