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

This is an old question, but I just ran across this requirement and found another solution that is worth answering here for others who come across this thread. I have put together an example based on that thread:

Sample Bean

class SampleBean {

    long id
    private String firstName
    String lastName
    def email

    Map asMap() {
        this.class.declaredFields.findAll { !it.synthetic }.collectEntries {
            [ (it.name):this."$it.name" ]
        }
    }
}

Test Class

class Test {

    static main(args) {
        // test bean properties
        SampleBean sb = new SampleBean(1,'john','doe','jd@gmail.com')

        println sb.asMap()
    }

}

The SampleBean I put a variety of fields to show that it works, this is the output of the println:

[id:1, firstName:john, lastName:doe, email:jd@gmail.com]
