2. Solutions
1), in the case of ensuring that the Hibernate.cfg.xml file is correct, does not include file constraints.
2), Reason: the introduction of the DTD constraint file location is incorrect.
3), I-XML file constraint file is
<! DOCTYPE hibernate-configuration Public
"-//hibernate/hibernate Configuration DTD 3.0//en"
"Http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd" >
4), change the constraint file to
<! DOCTYPE hibernate-configuration Public
"-//hibernate/hibernate Configuration DTD 3.0//en"
"Http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >
5), view hibernate-configuration-3.0.dtd and Hibernate-mapping-3.0.dtd files
