hibernate3.3.1和3.6.0版本的xml配置文件的写法

1.Hibernate 3.3.1 的XML的头：

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

<!-- *.hbm.xml文件 -->
<!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：

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

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

<!-- *.hbm.xml文件中也可以使用这个 -->
<!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：
