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

Person.java

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>
