안녕하세요 Hello JPA개발 강의를 듣던중

insert를 날려도 출력이 안되고

그냥 콘솔에 출력해도 출력이 안돼서 도저히 뭐가 문제인지 모르겠어서 질문남깁니다..

패키지 구조입니다

persistence입니다

pom.xml입니다

member클래스입니다

h2는 1.4.200버전으로 받은거같아요

jpa java JPA

OMG

안녕하세요.이진경님, 공식 서포터즈 OMG입니다.
.

catch문에 아래 코드를 추가해주세요

catch(Exception e) {

e.printStackTrace(); //추가

}

를 추가한 후 다시 실행한 메시지 전체 내용을 볼 수 있게 캡쳐 혹은 댓글에 복사 붙여넣기하여 첨부해주세요.

추가로 pom.xml의 h2버전을 1.4.199에서 1.4.200으로 변경해주세요. jaxb dependency는 자바8일 경우에 추가하지 않아도 됩니다.

.
감사합니다.

pom이랑 catch문 각각 수정했습니다..!

OMG

이 부분 보시면 파란색 칠한 코드 영역의 membes 가 오타로 보이는데요

members나 member로 바꿔보셔야 할거같아요

mappedBy에 membes로 지정하였을까요?
