Pass of user details from Spring security config to Controller Class

Question

Suggestion required after authentication from security config needs to pass the every user details to the APIs request.

Answer 1

The idea is that you can customise your authentication process such that after successful authentication , it will store the user object inside Authentication which can be retrieved by calling Authentication.getPrincipal().

Then in the controller method , you can access the user object representing the current user by :

//You have cast the user to the type of the user that you customzie manually   
MyCustomUser user = (MyCustomUser) SecurityContextHolder.getContext().getAuthentication().getPrincipal();

Or use @AuthenticationPrincipal to access it :

@GetMapping("/foo")
public String getFoo(@AuthenticationPrincipal MyCustomUser user) {

    
}
