흐앙 .....

 

이렇게 오류가 많을 수가,,,,,,

 

1. 첫번째 시도

 

같이 하는 친구한테 말했더니 mysql 접속할 때 mysql  ip등록 해줬던거 기억 나냐고 했다

와

그랬지?

 

https://jy-p.tistory.com/23

mysql 외부 접근 및 된 권한 확인

 

오 없네 없어 내 ip가 mysql 주소로 저장이 안되어있다.

 

 grant all privileges on *.*to'root'@'내ip' identified by '비밀번호';

 

2. 두번째 시도

https://oops4u.tistory.com/2583

jar : DB connection error

....

 

이것도 문제였지만 

aws의 저장소를 쓰고 있는데 인바운드에 ip주소를 추가해주었다. 

mysql/orora 로 

그랬더니 이제 잘된다^^
