Background:
Doing a desktop application (set the Spring boot environment), involves the TCP connection, I want to in the application is opened automatically enter the IP address and port number (IP address and port number can also change in interface)

As shown in figure:

After the running of the idea, can read and write data from the properties and normal but cannot read and write data after the packaged into a jar, this how to solve? Or what better way to store the IP address and port number?
