나는 봄 MVC에서 새로운 사람이다. 나는 STS를 사용하고 있으며 Spring MVC Template Project (Maven을 기본적으로 사용함)를 만들었다. 나는 Hibernate를 사용하려고 노력하고 있는데, 디폴트 자바 프로젝트에서/src 폴더에 hibernate.xml.cfg를 넣어야한다는 것을 안다. 제 경우에는 (maven을 사용하는 Spring MVC Template을 가지고) 이것을 읽었습니다. hibernate.cfg.xml을 src/main/resources과 /WEB-INF/classes에 넣어야합니다. 그러나 그것은 역시 도움이되지 못했습니다. 난 아직도 ClassNotFoundException가 있습니다MVC 템플릿 프로젝트는 hibernate.cfg.xml을 보지 않는다.
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from hibernate.cfg.xml
//AnnotationConfiguration
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
어쩌면 내가있는 hibernate.cfg.xml에 대해 뭔가를 작성해야 :
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

안녕하세요, 'andrew'가 패키지 인 경우 'HibernateUtil '생성자에서 'dom4j.jar'를 사용하려고합니다. – Stefan
얘들 아! 다들 감사 해요. 나는 아주 부주의했다. 그것은 작동합니다! 건배! –
