本文解决了一个关于Hibernate在启动时遇到的“必须声明元素类型hibernate-mapping”的错误。通过修改DTD声明，从http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd更改为http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd，成功解决了问题。

工程刚开始是正常工作的，但过了一段时间启动时报错如下：

2019-07-03 09:50:10,[ERROR] [org.hibernate.util.XMLHelper.error] Error parsing XML: XML InputStream(7) 必须声明元素类型 "hibernate-mapping"。
... ...
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateTemplate' defined in class path resource [applicationContext.xml]: Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: invalid mapping

Caused by: org.hibernate.MappingException: invalid mapping

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

改为

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

改完后，工程正常启动
