Spring Boot passing value / using method inside the application.properties

Question

For example:

I have a class called Path.java

In Path.java, I have getter method "getPort()" that returns int 8080

In application.properties, I want to use server.port = "getPort()"

How?

I want to externalize the datasource. I already have a class that grabs the information from the external .txt file. I need to use this class inside the application.properties.

Like, spring.datasource.url = ??getURL()??

Properties doesn't work that way. Their purpose is to gather a static content provided for the application as configuration. — Nikolas Charalambidis, May 30 '19 at 15:01
The answer is NO, you can achieve like this in the existing spring boot properties file. — Sambit, May 30 '19 at 15:02
There are ways, but they're far more complicated than the direct approach of extracting the information before launch (usually in a shell script) and setting the environment variable `PORT`. — chrylis -cautiouslyoptimistic-, May 30 '19 at 16:03

Thinking how you get the port in your Path.java . Then just reuse that information. There is no way to call a method in a properties file.
