本文介绍了一个使用Hibernate框架进行数据库映射的具体配置实例。通过XML文件定义了Book类与数据库表BOOK之间的映射关系，并设置了数据库连接属性。展示了如何通过Hibernate进行对象关系映射(ORM)并自动生成SQL语句。

Book

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="org.kimnin.hibernate">
<class name="Book" table="BOOK">
  <id name="id" column="BOOK_ID">
   <generator class="native" />
  </id>
  <property name="name" column="BOOK_NAME" />
</class>
</hibernate-mapping>

cfg

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