一个人有多个地址，公司地址、家庭地址等等。

Address1ntab.java

private int addressId;private String detailAddress;

Person1ntab.java

private int personId;private String personName;private int age;private Set address1n = new HashSet();

表结构：

-- 一对多单向 中间表DROP TABLE IF EXISTS join_1ntab;create table join_1ntab (    person_id int(11) not null unique,    address_id integer not null,    primary key (person_id, address_id)) ENGINE=InnoDB DEFAULT CHARSET=utf8;-- 一对多单向 地址表DROP TABLE IF EXISTS address_1ntab;create table address_1ntab (    address_id int(11) primary key auto_increment,    detail_address varchar(255)) ENGINE=InnoDB DEFAULT CHARSET=utf8;-- 一对多单向 用户表DROP TABLE IF EXISTS person_1ntab;create table person_1ntab (    person_id int(11) primary key auto_increment,    person_name varchar(255),    age int(3)) ENGINE=InnoDB DEFAULT CHARSET=utf8;alter table join_1ntab add constraint fk_1ntab_address foreign key (address_id) references address_1ntab(address_id);alter table join_1ntab add constraint fk_1ntab_person foreign key (person_id) references person_1ntab (person_id);

Address1ntab.hbm.xml

<?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"><hibernate-mapping>  <class name="com.ack.hibernateMapping.entity.Address1ntab" table="address_1ntab"><id name="addressId" column="address_id"><generator class="identity"/></id><property name="detailAddress" column="detail_address"/>  </class></hibernate-mapping>

Person1ntab.hbm.xml

<?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"><hibernate-mapping>  <class name="com.ack.hibernateMapping.entity.Person1ntab" table="person_1ntab"><id name="personId" column="person_id"><generator class="identity"/></id><property name="personName" column="person_name"/><property name="age"/><!--映射集合属性，join_1n是连接表表名--><set name="address1n" table="join_1ntab">  <key column="person_id"/>  <many-to-many column="address_id" unique="true"     class="com.ack.hibernateMapping.entity.Address1ntab"/></set>  </class></hibernate-mapping>

测试类：

public class Test_pa_1ntab {public static void main(String[] args) {Address1ntab add1 = new Address1ntab();Address1ntab add2 = new Address1ntab();Address1ntab add3 = new Address1ntab();Person1ntab p1 = new Person1ntab();Person1ntab p2 = new Person1ntab();add1.setDetailAddress("丽水市莲都区");add2.setDetailAddress("丽水市缙云县");add3.setDetailAddress("丽水市青田县");p1.getAddress1n().add(add1);p1.getAddress1n().add(add2);p2.getAddress1n().add(add3);p1.setPersonName("陈三");p2.setPersonName("陈大大");Session session = HibernateUtil.getCurrentSession();session.beginTransaction();session.save(add1);session.save(add2);session.save(add3);session.save(p1);session.save(p2);session.getTransaction().commit();}}

测试结果暂时报错，明天再看。
