bean 생성 안되는 문제. UnsatisfiedDependencyException

Question

서버 실행시 문제입니다.어노테이션 제대로 지정되어있고 컨트롤러/서비스 되있으며다오를 인터페이스 형태로 두고 implement를 하지 않는 형태의 구현부입니다.servlet-context를 확인시 bean 생성에 문제가 있는 것 같습니다.설정적인 부분이라 어느 부분부터 손대야 할지 막막해 질문드립니다. 에러메시지 ERROR: org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'boardController': Unsatisfied dependency expressed through field 'boardService': Error creating bean with name 'boardService': Unsatisfied dependency expressed through field 'boardDAO': No qualifying bean of type [com.seed.edu01.DAO.BoardDAO] found for dependency [com.seed.edu01.DAO.BoardDAO]: expected at least 1 bean which qualifies as autowire candidate for this dependency.
