接下来然我们看看，"生成"了什么样的映射文件（*.hbm.xml）:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class
name="dbdemo.User"
table="Users"
>
<id
name="userID"
column="LogonID"
type="string"
>
<generator class="assigned">
</generator>
</id>
<one-to-one
name="address"
class="dbdemo.Address"
cascade="none"
outer-join="auto"
constrained="false"
/>
<set
name="books"
table="Book_User_Link"
lazy="false"
inverse="true"
cascade="all"
sort="unsorted"

<key
column="UserID"

</key>
<many-to-many
class="dbdemo.Book"
column="BookID"
/>
</set>
<set
name="contacts"
table="Contacts"

inverse="true"
cascade="all"
sort="unsorted"

<key
column="User_ID"

<one-to-many

</set>
<property

type="string"
column="EmailAddress"
not-null="false"

<property

column="LastLogon"
not-null="false"

<property

column="Password"

<property

<!--
To add non XDoclet properties, create a file named
hibernate-properties-User.xml
containing the additional properties and place it in your merge dir.

</class>
</hibernate-mapping>
一旦创建完映射文件（放在classpath 中，并且和对象是"一对一"关系），你就可以通过Hibernate的接口和方法来操纵系统对象。
最后说一下，本文中例子下载包中的内容，每一个单独的例子都有main方法来运行：第一个例子：HibernateDemo.java，增加两个users，并且和address相关联（"一对一"）；第二个例子：HibernateDemoOneToMany.java，学习用Hibernate进行"一对多"映射；最后，第三个 |
