Я пытаюсь использовать AspectJ pointcut для args (), но при запуске в Springboot с tomcat выдает NullPointException.
Так как он сообщил об исключении нулевого указателя, и я отладил его, когда регистратор переменных переменной GenericFilterBeanявляется нулевым, я не знаю, нужно ли мне добавить дополнительную конфигурацию или что?
Буду признателен, если кто-нибудь знает, как решить эту проблему.
