hibernate如何在一对多关系中，级联删除一端集合中的部分元素

[ccx1024cc]

有一个person类和一个adress类。person为1端，adress为n端。
配置文件如下：

<?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">
<!-- 
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping package="test">
	<class name="Person" table="person_inf">
		<id name="id" column="person_id">
			<generator class="identity"/>
		</id>
		<set name="addresses"  inverse="true" cascade="all">
			<key column="person_id"/>
			<one-to-many class="Address"/>
		</set>
	</class>
</hibernate-mapping>

<?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">
<!-- 
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping package="test">
	<class name="Address" table="address_inf">
		<id name="addressID" column="address_id">
			<generator class="identity"></generator>
		</id>
		<property name="addressDetail" column="addressDetail"/>
		<many-to-one name="person" class="Person"
		column="person_id" not-null="true" cascade="all"/>
	</class>
</hibernate-mapping>

测试代码如下：

                Person person = (Person) session.get(Person.class, 3);
		Set<Address> address_temp = person.getAdresses();
		Iterator<Address> iterator = address_temp.iterator();
		while(iterator.hasNext()) {
			Address temp = iterator.next();
			person.getAddresses().remove(temp);
		}                          
//		session.delete(person);
		
		transcation.commit();
		session.close();
		factory.close();

但是现象就是，执行的语句只有Hibernate: select person0_.person_id as person_i1_1_0_ from person_inf person0_ where person0_.person_id=?，我看数据表了，adresses中的记录也没有被删除。新手入门，请教大神们啊。

我调试了一下，我的set集合中，取出来是空的，但是我的数据表格看上去没有错啊。adress和person的外键都能对上的。
