강사님 저 질문이있습니다.
아래는 4개 파일 다 소스 첨부했구요.
유효검사를 작성했는데, BindingResult result 했는데도 제대로 검사가 안돼서
초과하는 범위를 써도 에러가 0 이라고 뜹니다. 한 번 체크해주세요 감사합니다.
(pom.xml에도 아래와같이 추가는 잘 하였습니다.ㅜ..

너무 오래전 댓글이어서 분명 이미 해결 하셨을 것 같은데
저도 같은 증상으로 유효성검사에 실패했습니다.
저는 pom.xml에 추가한 Hibernate의 버전을 강사님이
제공하신 코드의 버전으로 바꾸니 해결되었습니다.
혹시라도 유효성검사가 안되시는 분들은 pom.xml설정의 Hibernate부분의 버전을 낮추어보세요.
