Grails - grails.converters.JSON - removing the class name

Question

Is there a way to remove the class field in a JSON converter?

Example:

import testproject.*
import grails.converters.*  
emp = new Employee()  
emp         


        

Answer 1

import testproject.*
import grails.converters.*  
import grails.web.JSONBuilder

def emp = new Employee()  
emp.lastName = "Bar"  

def excludedProperties = ['class', 'metaClass']

def builder = new JSONBuilder.build {
  emp.properties.each {propName, propValue ->

  if (!(propName in excludedProperties)) {
    setProperty(propName, propValue)
  }
}

render(contentType: 'text/json', text: builder.toString())
