발생 상황

간단한 토이 프로젝트 세팅 중, DB를 무엇으로 쓸 지 정해지지 않은 상태에서 가볍게 SQLite를 써보자고 하는 중이었는데요.

(SQLite는 단일 파일 DB로서 h2와 경량화된 데이터베이스이며 인메모리로 활성화할 수 있다는 공통점이 있습니다. 학습의 용도로 SQLite를 시도해보기로했어요.)

 

SQLite와 Spring JPA가 연동되지 않는 문제가 있었습니다.

발생 원인

JPA와 DB가 연동 되려면 Dialect가 필요한데 기존에 지원하던 SQLite용 Dialect가 Hibernate 6 에서는 더이상 지원하지 않았기 때문입니다.

👉 Dialect 패키지에 대한 참고링크 : https://docs.jboss.org/hibernate/orm/5.2/javadocs/org/hibernate/dialect/package-summary.html

 

org.hibernate.dialect (Hibernate JavaDocs)

Package org.hibernate.dialect Description This package abstracts the SQL dialect of the underlying database. A concrete Dialect may be specifed using hibernate.dialect.

대처

hibernate-community-dialects 의존성을 build.gradle 에 추가해주었습니다.

    implementation 'org.xerial:sqlite-jdbc:3.43.2.2'
    implementation('org.hibernate.orm:hibernate-community-dialects:6.1.7.Final') // 이부분을 추가해 주었습니다.
