톰캣을 이용해서 Spring 프로젝트를 실행하려고 하는데 해당 에러가 난다.

경고: 웹 애플리케이션 [ROOT]이(가) JDBC 드라이버 [net.sf.log4jdbc.sql.jdbcapi.DriverSpy]을(를) 등록했지만, 웹 애플리케이션이 중지될 때, 해당 JDBC 드라이버의 등록을 제거하지 못했습니다. 메모리 누수를 방지하기 위하여, 등록을 강제로 제거했습니다.

에러가 나는 이유는 무엇일까?

 

해당 에러는 Oracle JDBC 드라이버가 있는 두 개의 웹 앱이 서로 충돌한 것이다.

 

JDBC 드라이버 DriverManger는 모든 웹 앱에서 공유하는 JVM 전체 싱글톤에 자신을 등록한다.

두 개의 다른 웹 앱에서 동일한 JDBC 드라이버 등록이 두 번 있는 경우 문제가 발생할 수 있다고 한다.

 

아마 오라클 드라이버를 두 개 쓰고 있을 가능성이 크다.

 

그러면 이 에러를 해결하기 위해서는 어떻게 해야 될까?🤔

관련 JAR을 tomcat/lib 폴더에 넣으면 잘 작동한다.

tomcat의 lib 폴더 안에 sql jar를 넣는다.

또 JDBC 드라이버를 Tomcat의 lib 폴더에 넣으면 Tomcat을 다시 시작하지 않고 웹 앱을 재배포할 때 메모리 누수를 방지하는 데 도움이 된다고 한다.

ojdbc14-10.2.0.4.0.jar 를 다운받고 tomcat lib 폴더에 추가하면 된다.
