JdbcTemplate 기초 실행시 에러 발생

Question

13강을 따라하고 있는데 아래와 같은 에러가 발생합니다. 제가 강의를 듣는 환경은 STS4 를 사용하고 있고, JDBC API와 Oracle Driver를 같이 선택해서 프로젝트를 생성했고, 강의 Sample 그대로를 따라서 작성 후 내장 서버를 실행시키면 아래와 같은 에러가 발생합니다. 무엇이 잘 못 된 걸까요?

오라클 드라이버를 그레이들에서 선택하신 것 같습니다. 오라클 드라이버는 그레이들에서 선택이 된다고 하여도 제대로 동작을 하지 않습니다. 강의에서 말한 방법으로 수작업으로 환경 설정하여 사용하셔야 합니다. JDK 11에는 JRE가 따로 없으므로 JRE를 8 버전으로 설치하시고 강의 내용대로 오라클 드라이버를 위치시키시면 됩니다.
