안녕하세요.
데이터 베이스는 MariaDB 10.9 를 사용하고 있는데
엔티티 클래스 설계 후
실행하면 Category테이블 생성에 에러가 납니다.
Caused by: java.sql.SQLException: (conn=98) Can't create table studying.`category` (errno: 150 "Foreign key constraint is incorrectly formed")
보면 외래키가 설정되지 않은 parent_id 키가 생성이 되어있습니다.
답변을 작성해보세요.

혹시 기존 테이블 정보가 남아 있다면 삭제한 뒤 다시 시도해보시겠어요?
그래도 오류가 발생하면 아래 가이드를 따라 프로젝트 공유 부탁드립니다.
전체 프로젝트를 압축해서 구글 드라이브로 공유해서 링크를 남겨주세요.
구글 드라이브 업로드 방법은 다음을 참고해주세요.
https://bit.ly/3fX6ygx
업로드시 권한 문제 꼭 확인해주세요
공유 기본 설정은 비공개로 되어 있어 업로드 한 본인 계정만 접근이 가능합니다.
본인 계정이 아닌 링크를 통한 타 계정 접근이 가능한지 확인하는 방법은 업로드 한 구글 계정을 로그아웃하고 링크를 접속하여 "액세스 권한 요청 화면"이 출력되는지 확인을 해주세요.

올려주신 프로젝트에서 데이터베이스만 h2로 교체 후 실행했을 때 테이블이 정상적으로 잘 만들어졌습니다.
기존 테이블 정보가 충돌하는 것 같은데, 가능하시다면 테이블을 모두 삭제하신 후 다시 시도해보시겠어요?
