Grails / Groovy - Domain Object - Map of its Properties

Question

How can I get a map of the key/values of only the user-defined properties on one of my domain objects?

Problem is if I do this myself, I get my properties plus class

Answer 1

I think the best way is to use .properties on a domain object to get map of the fields in grails , tested in grails 2.1

class Person{
String firstName
String lastName

} 
def person=new Person()
person.firstName="spider"
person.lastName="man"
def personMap=person.properties
