我目前正在使用Interceptor为我的Web应用程序执行审计跟踪。
但是，当我尝试将详细信息保存到DB时，我遇到了以下问题：
org.hibernate.MappingException: Unknown entity: com.demo.domain.AuditLog
我认为我的applicationContext中存在映射问题，因为我的其他类工作正常。
我是否以正确的方式进行审计跟踪？

我找到了问题的根源。
return new Configuration().configure().buildSessionFactory();
从类路径获取默认的hibernate.cfg.xml文件。但是如何在web-inf中获取applicationContext-Hibernate.xml？
我无法使用servletContext，因为它不在servlet中。
HibernateUtil类：
public class HibernateUtil
{
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory()
{
try
{
// Create the SessionFactory from hibernate.cfg.xml
return 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;
}
}
