castor对xml、object数据进行换转Demo（一）

javabean对象数据通过castor转换成xml格式数据

 * (B):加入Mapping.xml进行

}

mapping_beanToxml.xml
转换规则配置文件如下

<!DOCTYPE databases PUBLIC   
"-//EXOLAB/Castor Mapping DTD Version 1.0//EN"  
"http://castor.exolab.org/mapping.dtd">
<mapping>
	<description>Basic mapping example</description>
	<class name="com.wj.castor.Person" auto-complete="true">
		<map-to xml="Person" />
		
		<field name="name">
			<bind-xml name="name" node="attribute" />
		</field>
		
		<field name="sex">
			<bind-xml name="sex" node="attribute" />
		</field>
		
		<field name="age">
			<bind-xml name="age" node="attribute" />
		</field>
	</class>
</mapping> 

转换生成结果文件person1.xml

<?xml version="1.0" encoding="UTF-8"?>
<array-list>
	<Person name="David" sex="女" age="24"/>
	<Person name="WJ" sex="男" age="25" />
</array-list>
