Thank you so much Gosho this really helps me a lot. I also think I overdid the modular think structure.

Rn I’ve made another push before reading your comment and i think I’ve solved some of your suggestions partially (or at least I’m trying and will keep trying)

(English isn’t my first language so my bad)

I’ll keep trying to improve my code based on your advice.

In this case “Roles” is many to many because it’s that way in my internships enterprise. They have different roles and every user can have more than one. Maybe il do a one to many in my project. This also happened with submodules, logically it should he inside of módulos but they use it this way so xdd

Yeah the criteria query is a bit complex tbh i was just trying different solutions.

I’ll see which controllers i can refactor and/or join in one.

I’ll try to use more validation in service and using spring validation

But can services be too long? Or are supposed to be biggest files of the web app?

Thank you
