关于hibernate总是报错 配置factory的id找不到，mapping配置文件Could not parse mapping document from input stream

Caused by: org.hibernate.InvalidMappingException: Could not parse mapping document from input stream

。。。。。。。。。。

Caused by: org.dom4j.DocumentException: www.hibernate.org Nested exception: www.hibernate.org

解决办法：

Person.hbm.xml配置文件中，

"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">改为：

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