How did you configure application parameters at your previous job?

In my previous role, I used several approaches to configure application parameters:

• Configuration files: properties files or YAML/JSON, where parameters could be stored and changed without recompilation.
• Environment variables: for configuring environment-dependent parameters (e.g., database, ports).
• Spring Framework (if applicable): used application.properties or application.yml for centralized configuration.
• Configuration profiles: created separate configurations for different environments (dev, test, prod).

Example of configuration via application.properties:

server.port=8080
datasource.url=jdbc:mysql://localhost:3306/mydb

This allowed flexible parameter changes without modifying the code.
