스프링부트 2.x버전에서 복합키 매핑 오류 관련 문의

Question

(기존의 질문드렸던 내용 https://www.inflearn.com/questions/1022839/%EB%B3%B5%ED%95%A9%ED%82%A4-%EB%81%BC%EB%A6%AC%EC%9D%98-%EB%A7%A4%ED%95%91-%EC%A7%88%EB%AC%B8-%EB%93%9C%EB%A6%BD%EB%8B%88%EB%8B%A4 의 추가 질문 입니다.)   안녕하세요. 항상 좋은 강의감사드립니다! 😉 😉 현재 회사에서 팀내사용을 목적으로 백엔드 프로젝트를 제작 중인 개발자입니다. 기존에 복합키 끼리의 매핑 관련해 질문을 드렸었습니다. 해당 부분은 스프링부트 3.x버전으로 진행했는데 이번에 운영목적으로 사용될 서버가 java11까지만 지원해 어쩔 수 없이 java17에서 java11로, 스프링 부트는 3.x에서 2.x버전으로 버전 변경을 진행했습니다.   근데 버전을 변경하고 나서 해당 복합키 매핑 관련진행시 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path

  이러한 오류가 발생하면서 빌드가 진행되지 않습니다. 버전 문제라고 생각한 이유는 코드를 그대로 보존 후(jakarta-> javax import변경) 진행했는데 java17에서는 오류없이 진행되고 java11에서는 위와같은   org.springframework.beans.factory.BeanCreationException: Error creating

오류가 발생하는 원인과 해결방법을 알 수 있을까요?   감사합니다!
