查找后发现是POJO的xml配置文件使用了Hibernate的头配置文件

把POJO的xml配置文件（下面这个是Hibernate的配置头文件，由于不是自动生成，当时写时直接从Hibernate.cfg.xml中拷贝过来）

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

改成POJO xml配置文件

<!DOCTYPE hibernate-mapping PUBLIC

"-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

的头就可以了
