접근이 거부되었습니다. 예외가 발생합니다.

5) 웹 기반 인가처리 DB 연동 - FilterInvocationSecurityMetadataSource (2) 강의 관련 질문입니다.

참고로, 현재 SecurityConfig 파일이 파일명으로 구분해서 Ajax 인증용과 폼인증 두개 입니다.

문제는 로그인까지 성공하고 /mypage 로 들어가면 접근 거부 예외가 생깁니다.

'org.springframework.security.access.AccessDeniedException: 접근이 거부되었습니다.'

SecurityConfig , AjaxSecurityConfig 설정파일명으로 구분했고 마지막에

설정 코드도 올렸지만 authenticationManager 같은 Bean 메서드들도 이름으로 구분했습니다.

사용자정보, 권한정보등 제대로 갖고 왔는데 어디가 잘못된건지 잘모르겠네요..

혹시 시큐리티 설정파일에서 서비스 클래스 두가지를 사용해서 그런지 의심도 되고 그렇네요..

private final SecurityResourceService securityResourceService;

private final UserDetailsService userDetailsService;

아래에 도움이 될까 해서 디버깅화면 캡쳐해서 올렸습니다.

그리고 코드는 아래 깃허브에 올렸습니다.

감사합니다.

AbstractSecurityInterceptor 클래스

UrlFilterInvocationSecurityMetadataSource 클래스

RoleVoter 클래스

ExceptionTranslationFilter 클래스

FormAccessDeniedHandler 클래스

AccessDeniedException 클래스

웹페이지에는 흰 배경만 나타나고 302 코드를 반환하네요.
