Code Review Request
Hello! Does anyone have a moment to review my code? I have made a very simple project similar to Google Dropbox / the explorer with Spring Boot and Spring Security. Please look over the file structure, as I am trying to follow the Service-Controller-Repo structure. Otherwise please give me suggestions on how I can improve my overall code! Thanks!

can request be validated before reaching the controller?
hey guys. im talking with a friend of mine and he mentioned that in php language you usually validate the data BEFORE it reaches the controller. i was wondering if this can be done in Java Spring app? as i understand this idea cant be done in Java Spring app. the controller in Spring app is the entry point to the application. and you cant really do much in Dispatcher servlet. what do you guys think? thanks in advance.

Performance & Readability Improvements
I do have quite big classes, I wanted to break them down into smaller classes but i entered issues while doing that. My goal is better readability, equal performance compared to now when all modules enabled and better performance than now when all modules disabled. Im trying to avoid class loading,initialisation and registration of handlers that arent needed aswell as them registrated multiple times.
For example if i have a field that controls whether a module is going to be loaded or not, but the field also needed for a module and changing during runtime, then i have basically one part of the module i the class that refers execution to modules and one part in the module class, which doesnt look good. Also if i have smaller classes i need more total time to load these and they consume more file size and metaspace memory? I also noticed if i load on demand that i will get minor lag spikes. If i though keep them in big classes then i will have the best performance when everything is used and loaded but bad performance when only a fraction is enabled....

question about Java
I am reading that when Java was first introduced, the developers and designers anticipated that Java GUI programming would be the most predominant form of Java programming, even eclipsing other forms of windows programming (such as C++ and toolkits). What are some reasons for why this did not happen?
VS Code not executing program

Websocket Postman
I just wanted to check if someone notice anything wrong in my code.
Basically, what I want to do is that when a new user registers, I want the admins to be notified with "New user has been registered", but I want to do it in real-time using WebSocket.
I'm testing my WebSocket URL ws://localhost:8080/ws, and I successfully connect to it. I also subscribe to the destination:
