Я создаю приложение Spring Boot MVC, которое требует проверки подлинности для некоторых методов контроллера.Для этого я не использовал какую-либо инфраструктуру управления идентификацией, предоставляемую Spring, потому что мне нужно сделать это самостоятельно, поскольку это школьный проект.Поэтому я планировал использовать Аспектно-ориентированное программирование в Spring AOP и создать аннотацию AuthentificatedOnly примерно так:
@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface AuthentificatedOnly {
}
Я также создал аспект, который должен соответствовать этой аннотации, и вывел исключениеесли пользователь не прошел аутентификацию (с созданным мною UserManager, с автоматическим подключением к Spring IOC, и это полностью оперативно, поскольку я тестировал его непосредственно на некоторых контроллерах, поэтому проблема не может быть в диспетчере пользователей).Аспект выглядит следующим образом:
@Aspect
@Component
public class AuthentificationCheckAspect {
@Autowired
private IUserManager userManager;
@Around("@target(dgl.dgladmin_rest.model.auth.AuthentificatedOnly)")
public Object checkAuthentification(ProceedingJoinPoint joinPoint) throws Throwable{
System.out.println("checking authentification for " + joinPoint.getSignature().toShortString());
if(!userManager.isConnected())throw new AuthentificationException();
return joinPoint.proceed();
}
}
Я использую свою аннотацию для некоторых методов контроллера, которые возвращают представление или ModelAndView, например:
@Controller
public class UserController{
[...]
@AuthentificatedOnly
@GetMapping("/users")
public String userPage(Model model){
return "users";
}
[...]
}
Когда я запускаю свое приложение, оно выдаетисключения и остановки:

Я считаю, что проблема заключается в аннотации @Around в моем аспекте, потому что приложение запускается нормально, если я заменю аннотацию @Around на аннотацию @Pointcut, но тогда я могу вызватьзатронутые методы и ничего не происходит (даже System.out.println не достигнут, поэтому я считаю, что этот аспект никогда не используется).
