Hibernate一对一外键关联

Hibernate一对一外键关联由"many-to-one"节点定义：

<?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="com.domain">
	<class name="Person">
		<id name="id">
			<generator class="native" />
		</id>

		<property name="name" unique="true"/>
		<many-to-one name="Passport" class="com.domain.Passport"></many-to-one>
	</class>
</hibernate-mapping>
