인프런 커뮤니티 질문&답변

안녕하세요!

김영한 강사님의 강의를 들으며 제 프로젝트에 맞춰서 강사님 코드를 클론 코딩해서 공부를 하던 중 하단과 같은 오류가 떠서 문의드립니다.

Error creating bean with name 'likeApiController' defined in file [/Users/gimnayeon/Desktop/GreenProject/GrinGreen/out/production/classes/com/grin/GrinGreen/api/LikeApiController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'likeService' defined in file [/Users/gimnayeon/Desktop/GreenProject/GrinGreen/out/production/classes/com/grin/GrinGreen/service/LikeService.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'businessRepository' defined in file [/Users/gimnayeon/Desktop/GreenProject/GrinGreen/out/production/classes/com/grin/GrinGreen/repository/BusinessRepository.class]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.grin.GrinGreen.repository.BusinessRepository]: No default constructor found; nested exception is java.lang.NoSuchMethodException: com.grin.GrinGreen.repository.BusinessRepository.<init>()

오류 그대로 기본 생성자가 없다는 거 같은데 제가 아직 부족해서 그런지 아무리 찾아봐도 어디서 문제인지 모르겠어서요.. 도움 부탁드립니다..

저는 멤버 가입 후 그 멤버로 업체를 만들어서 업체 목록을 조회를 하려고 했습니다!
