本文详细介绍了Hibernate 3.3.1和3.6.0版本中配置文件hibernate.cfg.xml及*.hbm.xml的DTD声明方式，并给出了正确的DTD声明示例。若DTD声明错误，将导致Hibernate无法正确解析配置文件。

1.Hibernate 3.3.1 的XML的头：


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


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

2. Hibernate 3.6.0 的XML的头：

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


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


<!doctype hibernate-mapping public
"-//hibernate/hibernate mapping dtd 3.0//en"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

XML文件的头不能写错，否则会抛如下异常：
