분명 방금 전까지 잘됐는데..

갑자기 에러 남 ; 말이 안되는데 ..

 

 

원인 !

- AWS RDS 배포하면서 url 형식을 잘못 기입했다.

-> jdbc:mysql://[RDS엔드포인트]:3306/[DB명]?serverTimezone=Asia/Seoul&characterEncoding=UTF-8

--> 배포 버전은 잘 동작했는데 로컬에서는 여전히 안돌아가서 의존성을 추가해줬다.

 

⬇️ build.gradle

...
dependencies {
	...
	// entityManagerFactory
	implementation group: 'org.javassist', name: 'javassist', version: '3.15.0-GA'
}
...
