Could not get JDBC Connection 오류 보고

이전에 사용한 것은 모두 mysql 데이터베이스인데 이번 프로젝트는 Oracle 데이터베이스에 사용하고 환경을 설치한 후에 데이터베이스 연결 테스트를 실시해야 한다. 타임즈 Could not get JDBC Connection;에 대한 오류입니다. 자세한 오류는 다음과 같습니다.

### Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is java.sql.SQLException: oracle.jdbc.OracleDriver] with root cause

이번에 아주 저급한 오류를 범했습니다. 연결할 때 Oracle 데이터베이스입니다.pom 파일은 인용된 확실한 Mysql 드라이브로 Could not get JDBC 연결 오류를 초래했습니다. 그리고 이전 프로젝트에서ojdbc6-0.0.1-SNAPSHOT를 찾았습니다.jar의 패키지를 Eclipsece를 통해 Maven 로컬 창고에 추가한 다음pom에 추가합니다.xml에서 인용하면 다시 시작하면 됩니다!
