struts 2配置文件：struts.xml
?xml version="1.0" encoding="GBK"?
!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "[url]"[/url]
struts
constant name="struts.i18n.encoding" value="GBK"/
constant name="struts.custom.i18n.resources" value="messageResource"/
package name="lee" extends="struts-default"
action name="add" class="org.yeeku.action.AddPersonAndSon"
resultwelcome.html/result
/action
/package
/struts
对应的映射文件：Son.hbm.xml
?xml version="1.0" encoding="GBK"?
!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN" "[url]"[/url]
hibernate-mapping package="org.yeeku.model"
!-- 每个class元素映射一个持久化类 --
class name="Son" table="son"
id name="id"
generator class="identity"/
/id
property name="sonName"/
property name="sonAge"/
many-to-one name="parent" column="person_id" not-null="true"/
/class
/hibernate-mapping
