Problem Background

[[See Video to Reveal this Text or Code Snippet]]

While this setup works for a single store, what if you want to add more stores? In a traditional setup, this would require code changes and redeployment of your application. Thankfully, there’s an effective solution to enable dynamic loading of configurations.

Desired Configuration Structure

Summary

Benefits of This Approach

Scalability: Easily add new store configurations.

Maintainability: Less need for code changes; just edit properties.

Efficiency: Load configurations at application startup without additional complexity.

By following these steps, you can effectively manage your dynamic configurations in a Spring Boot application. Happy coding!
