책 이름 등록하고 사용자가 대여하는 기능을 하고있는데책 대출 기능에서 사용자이름과 책이름을 입력하고 저장하게되면내부 서버오류 500 뜨면서 java.lang.NullPointerException: null 이라고 나옵니다.구글링을 해봤는데 해결이 안되서 질문드립니다. 

ArticleApiController에서 return ArticleService.index(); 입력하고 create누르면 ArticleService 클래스에이렇게 static으로 정의가 됩니다. 상관없을까요? 또,static으로 정의되는 이유가무엇일까요? 떼면 빨간줄이 생기네요  이상태로 Talent 로 테스트를 해보면(get)이런 에러가 뜹니다.ArticleService.java:17은 이거구요, ArticleApiController.java:25는이겁니다 이유가 무엇일까요? ㅜㅜ... 이런 현상이 일어나는 이유가 궁금합니다

안녕하세요기존에는 CustomUserDetailsService 로 인증처리를 완료했는데 이때 AuthenticationProvider의 anthenticate 메서드 역할은 우리가 만든 loadUserByUsername + 스프링 시큐리티가 기본으로 제공하는 역할을 이용하였고 이번에 새로 추가한 CustomAuthenticationProvider 는AuthenticationProvider의 anthenticate 역할을 커스터마이징 했다고 생각하면 되는걸까요 ?

(예)[질문 내용]강의를 보고 엔티티를 설계하여 프로젝트를 진행하고 있습니다. 강의에서 말씀해주신대로 모든 FetchType을 LAZY로 하여 개발하고 있는데 문득 지연로딩이 실제로 어떤 상황에 필요한지가 궁금해졌습니다.강의에서 말씀해주신대로 연관관계 매핑 데이터를 즉시 가져오지 않고 필요할 때 사용할 수 있도록 할 때 지연로딩을 사용한다는 것은 이해했습니다.실무에서 어떤 상황에 적용되는지 찾아보니, 여러 이미지들을 스크롤하면서 이미지를 실제로 화면에서 보게 될 때 사용하면 효율적이라는 포스팅을 보았습니다.그런데 또 실무에서는 OSIV를 off한다고 보았습니다. OSIV가 off라면 영속성 컨텍스트가 Service, Repository에서만 살아있게 되어 어쨌든 Service 단에서 모두 처리해야 하는데 그렇다면 지연로딩이나 즉시로딩이나 별 차이가 없는 것 아닌가요?? 혹시 제가 잘못 알고 있는 것이 있는지, 어떤 상황에서 지연로딩을 사용하는 것이 좋은지 궁금합니다. 감사합니다:)
