2. 문제 원인

이 경고는 Spring Boot의 JPA 기능에서 자동으로 설정되는 spring.jpa.open-in-view 속성에 관한 것입니다. 이 속성은 Open Session In View (OSIV) 패턴을 활성화하거나 비활성화하는 데 사용됩니다. OSIV 패턴은 JPA 세션을 뷰 렌더링 중에 열린 상태로 유지하여 지연 로딩 관련 문제를 해결하는 데 도움이 됩니다.

3. 해결 방법

Spring Boot Properties 설정을 수정합니다.

# vim application.properties

spring.jpa.open-in-view=false

# vim application.yml

spring:
  jpa:
    open-in-view: false

4. 해결 완료
