Translating Java objects and XML into each other

Castor-xml.jar Package

--castor can complete Java and the XML conversion of each other:

1) take advantage of mapping config, group Javaobject xml

we set it before mapping.xml xml Mapping.xml How are configuration files configured account What about this object

Mapping.xml configured as follows

<?xml version= "1.0" encoding= "UTF-8"?>

<! DOCTYPE mapping Public "-//exolab/castor mapping DTD Version 1.0//en" "Http://castor.org/mapping.dtd" >

<mapping>

<class name= "Com.hoo.entity.Account" auto-complete= "true" >

<map-to xml= "Account"/>

<field name= "id" type= "integer" >

<bind-xmlname= "id" node= "attribute"/>

</field>

<field name= "Name" type= "string" >

<bind-xml name= "name" node= "element"/>

</field>

<field name= "Email" type= "string" >

<bind-xml name= "Email" node= "element"/>

</field>

<field name= "Address" type= "string" >

<bind-xml name= "Address" node= "element"/>

</field>

<field name= "Birthday" type= "Com.hoo.entity.Birthday" >

<bind-xml name= " birthday " node= "element"/>

</field>

</class>

<class name= "Com.hoo.entity.Birthday" >

<map-to xml= "Birthday"/>

<field name= "Birthday" type= "string" >

<bind-xml name= "Birthday" node= "attribute"/>

</field>

</class>

</mapping>
