자꾸 에러가남

entity 생성 시간을 자동으로 입력해주는 

@CreationTimeStamp를 갖다 쓰려고 하는데 지원하지 않는 property type이라고함

Your import is wrong. As @raviiii1 suggested, instead of java.security.Timestamp use java.sql.Timestamp

 

 

 

알고보니 TimeStamp를 import java.security.Timestamp;로 땡겨 써서 그런 것 같음

 

 

 

 

 

성공.

 

 

[에러 이유]
Timestamp를 잘못된 라이브러리에서 import했었다.
 
import java.security.Timestamp; (X)
import java.sql.Timestamp; (O)
