映射文件如下：
<?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">
<hibernate-mapping>
<class name="com.ffcs.cip.entity.ShopDict" table="cip_shop_dict">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="identity" />
</id>
<many-to-one name="parent" class="com.ffcs.cip.entity.ShopDict" column="parent_id" />
<property name="name" type="java.lang.String">
<column name="name" length="50" />
</property>
<property name="orderId" type="java.lang.Integer">
<column name="order_id" />
</property>
<set name="childs" inverse="true" cascade="all-delete-orphan" lazy="true" table="cip_shop_dict">
<key column="parent_id"/>
<one-to-many class="com.ffcs.cip.entity.ShopDict"/>
</set>
</class>
</hibernate-mapping>
数据库设计如下：
create table dict
(
`id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
`parent_id` int(11) NOT NULL DEFAULT '0' COMMENT '父ID',
`name` varchar(50) DEFAULT NULL COMMENT '字典名称',
`order_id` int(11) DEFAULT NULL COMMENT '排序',
PRIMARY KEY(`id`)
)ENGINE=InnoDB DEFAULT CHARSET=utf8;
