该错误消息说，（埋在一个大的堆栈跟踪）：
Document root element "hibernate-mapping", must match DOCTYPE root "hibernate-configuration"
这是因为在你的Person.hbm.xml文件，你有
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
在这里你也许应该有
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
这DOCTYPE有根标签相匹配。
这很简单
1.创建构造函数
public Person(){}
这是在休眠最主要的。 它会通过此构造的对象映射（使用Java反射机制的概念）
2.Understand的DTD。 有两种类型的DTD可用映射DTD和配置DTD的
映射 - DTD是
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
配置DTD是
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
hibernate.cfg.xml的是配置文件Person.hbm.xml是映射文件，因此改在DTD Person.hbm.xml
它将运行。
在一定条件下InvalidmappingException出现请仔细阅读
我们将使用的，而不是我们用那么这个例外发生一定的ID标签。
在POJO类声明的数据成员像数据库“名” U声明“名” OK，然后在映射文件你所写的只是简单的术语，我们可以说，像什么ü在ID标签名称声明属性及其相应的没有数据成员值在POJO类，然后只有一个错误出现InvalidMappingException。
当orthis列名不完全匹配相应的数据库归档SQLGrammarException出现。
我也有此错误消息。 但在我的情况下，类名是错误的。 添加正确的包，并根据波纹管例如类名。
