[Spring Project]org.apache.catalina.LifecycleException: 구성요소 [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]을(를) 시작하지 못했습니다.

 

#프로젝트 실행 시 발생하는 오류

→ 프로젝트 클린 후 재부팅 (실패)

→ window → preference → maven → user settings : repository 경로 확인 → (이클립스 종료 후) repository 폴더 삭제

    → 프로젝트 실행 (실패)

→ web.xml 오타 체크 (???)

→ 해결방법 찾는 중
