Autenticación de inicio de sesión SpringBoot-AOP

Si se detecta que Cookie o Redis no tiene un token, significa que el inicio de sesión es anormal y salta a la página de inicio de sesión del código de escaneo.

}

• @ResponseStatus (HttpStatus.FORBIDDEN): debido a que la excepción devuelta a la recepción es 200, porque fue detectada, entonces cómo modificar este código de estado depende de esta anotación.
