How Can I flatten my DTO into VO - dozer

Question

Here is a sample simple scenario that I want to map. I have a DTO as follows
Class Person {
String Name;
List<Contact> contacts;
}
Class Contact {
String type; //values 'home', 'work', 'mobile' etc
Phone number;
}
Class Phone {
String areaCode;
String number;
}
I need to map it to a VO object as follows
Class PersonVO {
String Name;
PhoneVO homePhone;
PhoneVO workPhone;
}
Class PhoneVO {
String areaCode;
String number;
}
Is there an easier way to map them using dozer or I have to use customconvertors? how can I use default mapping for phone to phoneVO?

Answer 1

You cannot map Person DTO and PersonVO without using a CustomConverter,
because Person's Phone 'number' variable gets it's value based on whether
'type' variable contains values 'home' or 'work', and so on. Dozer cannot handle such
conditional cases.
However, default mapping for Phone and PhoneVO alone is very simple:
<mappings xmlns="http://dozer.sourceforge.net"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://dozer.sourceforge.net
http://dozer.sourceforge.net/schema/beanmapping.xsd">
<mapping>
<class-a>{package-name}.Phone</class-a>
<class-b>{package-name}.PhoneVO</class-b>
</mapping>
</mappings>
