강의를 진행하던 중 Could not determine type for: java.util.List, at table 이라는 error가 발생하였다.

 

문제가 어디서 터지나 봤더니

 

위 코드에서 List<String> roles를 Entity로 mapping 할 수 없어서 오류가 발생 한 듯 했고

 

구글링을 통하여 @OneToMany 를 붙여주면 해결 할 수 있다는 글을 읽고서 붙여 봤더니

 

위와 같은 오류가 생겼고 이를 바탕으로 다시 구글링 한 결과

 

@OnetoMany와 비슷한 기능을 하게 해주는 @ElementCollection 을 붙이면 해결 된다는 글을 보았고

 

error 없이 구동에 성공했다

 

@OneToMany 와 @ElementCollection 에 대해서 정리해봐야겠다.
