현재 AutoProxyConfig, main의 코드는 위와 같고 이를 실행하면 다음과 같은 오류가 발생합니다

결국 ThreadLocalLogTrace에서 response에서의 TraceStatus가 null값이 들어가서 생긴 NPE 오류라고 나오는데 이전에 AnnotationAwareAspectJAutoProxyCreator가 아닌 직접 빈 후처리기를 만들고 등록할때까지는 아무런 오류가 없었는데 AnnotationAwareAspectJAutoProxyCreator를 등록하고 난 후에 main자체가 띄워지지가 않는데 어디가 문제인가요??

 

build.gradle에는 aop적용하였고 버전을 낮춰봤는데도 버전문제가 아닌거 같습니다
