I'm sharing here my latest project which is a library for Spring Boot apps that exposes a full database admin panel generated automatically based on your JPA annotations. Similar to the Django admin panel, if you're familiar with that. It doesn't require to adapt your existing application's code; it works by including the JAR and performing a couple of configuration steps.

I've already developed a considerable amount of features, but I still have to test it thoroughly with different Spring/JPA configurations and this is where it might still break frequently. User feedback would be invaluable on this aspect, but even if you don't try the code I'll gladly accept feedback about the idea or features you'd think might be useful.

Cheers!
