我是 Spring MVC 的新手。我正在使用 STS，并且创建了 Spring MVC 模板项目（默认使用 Maven）。我正在尝试使用 Hibernate，我知道在默认的 Java 项目中我必须将 hibernate.xml.cfg 放在 /src 文件夹中。我已经读过，在我的情况下（使用带有 maven 的 Spring MVC 模板）我必须将 hibernate.cfg.xmlsrc/main/resources和/WEB-INF/classes. 但这也没有帮助。我仍然有 ClassNotFoundException：
SEVERE: Servlet.service() for servlet [appServlet] in context with path [/mvc] threw exception [Handler processing failed; nested exception is java.lang.ExceptionInInitializerError] with root cause
java.lang.ClassNotFoundException: org.dom4j.DocumentException

这是我的 hibernate.cfg.xml：
<?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">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="connection.url">jdbc:sqlserver://localhost:1433</property>
<property name="connection.username">hibernate</property>
<property name="connection.password">123456</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>

</session-factory>
</hibernate-configuration>
我的 HibernateUtil 类：
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;
}
}
也许我应该在 web.xml 或 servlet-context.xml 中写一些关于 hibernate.cfg.xml 的内容？我正在解决这个问题大约 7 个小时，我什至尝试将 hibernate.cfg.xml 放在项目的每个文件夹中，但它没有帮助。
