为什么会发生这种HibernateException？

Answer 1

这很可能是因为在您正在使用的Hibernate jar中不存在的hibernate.cfg.xml顶部引用了DTD。

假设您没有使用Hibernate 2.0版，请在您的hibernate.cfg.xml中检查一下：

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

如果您使用XML hbm文件进行实体映射，那么您可以在那些XML文件中使用：

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

HibernateException＆＃34;无法解析配置：hibernate.cfg.xml＆＃34;运行简单的Hibernate应用程序时出错
