Spring passing parameter values via annotations for current user

Question

I'm developing some social system, and I want make some annotation which automatically inject loggedUser to method parameter.

I've tried to use a AOP but official documentation says:

Return types are restricted to primitives, String, Class, enums, annotations, and arrays of the preceding types. Methods can have default values.

public void getLoggedUserDetails( @CurrentUser User user){
//some logic
}

It it possible to do that with Aspects and annotaion or I should look for another solution?

Answer 1

there is a @AuthenticationPrincipal and it works for controller method parameters. see here

@Controller
class UserController {


    @GetMapping("/self")
    public ResponseEntity<User> demo(@AuthenticationPrincipal User user){
        return new ResponseEntity<>(user, HttpStatus.OK);
    }

You can also create a custom annotation:

@Target({ElementType.PARAMETER, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@AuthenticationPrincipal
public @interface CurrentUser {}
