spring + hibernate class not

나는 실행을 위해 노력하고 있으며 문제가있는 간단한 웹 어플리케이션을 가지고있다. Java EE 6 애플리케이션을 Spring으로 마이그레이션했습니다. 그것은 최대 절전 모드로 시작하지만, Spring이 엔티티를 참조하는 명명 된 bean을 만들려고 할 때 ClassNotFoundException을 얻습니다.spring + hibernate class not

봄에 WAR의 WEB-INF/lib 안에 jar 파일이 보이지 않는 이유는 무엇입니까? 프록시 문제가 있습니까?

스 니펫 (있는 경우)을보고 싶은 파일을 알려주세요.

EDIT : stack trace attached - 간략하게 스택 추적에서 정규화 된 클래스 이름을 수정했습니다. 나는 또한 나의 봄 콩 윤곽을 붙였다. 또한 참고로, 내 엔티티 클래스는 모두 다른 jar 파일에 있습니다 (의도적으로). 나는 그것이 어떤 문제를 일으키는 것으로 믿지만, 왜 확실하지는 않습니다.

확인하고 WEB-INF/lib 디렉토리의 내용이 WAR에 번들 또는에서 시작 분해 디렉토리로 이동 한 경우를 참조하십시오. – duffymo

전체 스택 추적 및 오류 메시지는 무엇입니까? 일반적으로 메시지는 찾을 수없는 클래스를 알려줍니다. – beny23

이미 WAR 파일을 확인 했으므로 그대로 있습니다. 그러나, hibernate의 로그를 검토 한 후에, 주석이 달린 클래스들을 탐지하기위한 시작 시간이 0ms 였기 때문에 어떤 엔티티들도 발견되지 않았다고 Hibernate는 보지 않는다. 나는 더 이상 최대 절전 모드를 확인하지 않았다. – Walter

내가 그것을 알아 냈어, 내 persistence.xml을 외부 항아리를 가리키는에서 지정했다.
