表结构：

create table primaryTable(
primaryTableId int primary key,
refKey varchar(16)--被关联键，注意不是id
)ENGINE=innodb

create table childTable(
childTableId int primary key,
linkRefKey varchar(16)--关联到primaryTable表中的refKey
)ENGINE=innodb

hibernate映射文件：(注意红字部分)

primaryTable.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">

</class>
