로그에 따르면 클래스 경로에 com.microsoft.sqlserver.jdbc.SQLServerDriver 클래스가 없습니다. classpath에 있는지 확인 했습니까? 수동으로 또는 빌드 스크립트 (Maven/Gradle/Ant)에 추가해야 할 수도 있습니다. –
개발 중에는 sqljdbc4.jar을 사용하여 데이터베이스에 액세스합니다. 이 항아리를 포함해야합니까?! 컴파일 할 때 또는 특정 클래스 인 경우 누락 되었습니까? – Klelund
필요한 jar 파일을 클래스 "com.microsoft.sqlserver.jdbc가 포함 된 WEB-INF/lib 폴더에서 누락 된 것 같습니다 : 자세한 내용
서버 로그 서버 로그를 참조하십시오. SQLServerDriver "입니다. jar 파일을 해당 폴더에 넣고 다시 시도하십시오.
