controller, service 등의 오류가 보여서 몇시간을 검색한 결과 스택오버플로우를 통해서 해결했다...

나의 경우는 myBatis를 사용한 xml파일에서 오타때문에 발생한 오류였다....ㅠㅠ

해당 쿼리를 주석 처리하니 정상 작동... 몇시간을 뻘짓했는데..

저 오류가 나면 controller, service 어노테이션 문제라고 생각을 했던것이 편겨이였다.

데이터 소스 쪽이나 application.properties 이쪽을 보라고 한것에 힌트로 마이바티스 xml파일 수정하니 해결했다.

다른 분들도 저런 오류면 어노테이션 말고 db쪽 설정이나 쿼리쪽 봐주세요.
