안녕하세요. 현재  아래의 수업을 듣고 있는 수강생입니다. 

" 강의명 : 실전! 스프링 부트와 JPA 활용1 - 웹 애플리케이션 개발/ 6강" 

어플리케이션 테스트를 하려고 하는데 계속 안됐습니다. 그래서 제공해주신 자료 모든 내용을 복사 붙여넣기를 해도 계속 Failed to load ApplicationContext 라는 문제가 발생하고 있습니다. 띄어쓰기 확인해봤지만 안됩니다. 제공해주신 pdf / 아래에 질의응답게시판에 작성하신 내용 또한 복사해서 붙여넣기도 해봤습니다. \main\resources 폴더 안에 있는 것도 확인해봤고요. 그래도 안됐습니다.

그런데  혹시 몰라서 yml을 삭제해버렸는데 작동이 잘 되더라고요.  

혹시 왜 이런 문제가 발생했는지 문의 드려도 괜찮을까요? 장기적으로 이런 문제가 또 발생하는데 yml이 필요한 경우가 있을 경우 어떻게 대응해야 할지 감이 오지 않습니다. 연말 잘 보내세요. 감사합니다.

안녕하세요. SJ BAE님

혹시 h2 데이터베이스 서버를 실행하셨는지요?

만약 그렇다고 하면 잘 동작하지 않은 애플리케이션 전체 프로젝트를 압축해서 올려주세요.

감사합니다.
