log4jdbc-log4j2 적용중 오류

log4jdbc-log4j2 메이븐추가도했고 

log4jdbc-log4j2.properties도 만들어주고 

driverClassName과 url도 변경해주었는데

오류가난다...

로그는 다음과 같다

오류내용을 보면 root-context.xml에서 빈을 생성하는데 오류가 발생하였고, driverClassName에서 문제가 있다는것을 보고 driverClassName의 오타를 확인 해보았지만 정확했다. 그렇다면 driverClassName문제가 아니였던것이다.

다음내용을 보면 Log4j2 라이브러리를 찾을수 없다고 되있는데 이부분이 문제였던거다!

Log4j2는 api와 core로 나누어져있다. (참고: https://logging.apache.org/log4j/2.x/maven-artifacts.html)

Log4j-api와 Log4j-core 메이븐을 추가하면 해결된다.
