how can i get data from Principal in controller?

Question

I'm using Spring Boot and Spring Security.

I would like to get current authenticated user data inside my userController (not only the name, username, password and authorities)

I found on differents links I can use Principal in my requestMapping method. But how can I data on this principal please ?

If I run in debug mode I can see all data I need inside the Principal variable.

@GetMapping("/users")
public ResponseEntity<?> getAllUsers(Principal principal) {
    
    return this.userService.getAllUsers();
}

i saw this post, but I expect it is possible to get data from Principale since i can see data in variable debug mode, no ? — Bertrand PETIT, Mar 26 '21 at 13:57
you need to cast it to a userdetails object so that the compiler knows what object it is and what methods exist on the object. — Toerktumlare, Mar 26 '21 at 13:59
It does not work with Principale. But it works with Authentication but it does not give me more details than username, email and authorities. I need the others variables — Bertrand PETIT, Mar 26 '21 at 14:54

you hard cast it to a user details object:

final UserDetails currentUser = (UserDetails) ((Authentication) principal).getPrincipal();
