Question

이것은 stackoverflow에 대한 첫 번째 게시물입니다! 그러나 나는 UIO의 마스터 학생이므로 많은 도움을 얻은 후에 (심지어 선택하기 만하면) 도움이되지는 않지만 아마도 문제를 더 잘 이해할 수있는 곳으로 향하는 포인터 일 것입니다! 그리고 문제를 보여주는 내 방식이 마음에 들지 않는다면 그 점에 대해 의견을 말하십시오. 그러면 다음에 더 나아질 것입니다!

Answer 1

제약 조건 위반 예외는 일반적으로 데이터를 삽입하려고 할 때 발생합니다 테이블 행에 설정된 제약 조건을 위반하는 값으로

열에 삽입 된 값이 집합을 위반하지 않는지 확인하십시오. 예를 들어 열에 고유 색인이있는 경우 값이 다른 레코드와 고유해야합니다.

Answer 2

쿼리가 플러시를 트리거하여 ConstraintViolationException이 발생합니다. 불행히도 저장 시간에이 오류가 표시되지 않았지만 오류는이 쿼리와 관련이 없습니다.

이 쿼리를 수행하기 전에 삽입물을 조사하십시오. 절대로 (.saveAndFlush()/.save (flush : true))를 저장하여 불량 인서트를 즉시 확인하려고 할 때 플러시를 시도하십시오. Hibernate와 JDBC가 올바른 오류 메시지를 제공하여 정확히 무엇을 잘못했는지 정확하게 알려줄 것입니다. 이 비 특약 제약 위반.
