Retrieving data using Grails Domain returns with a Class Key by default

Question

I'm working with a Grails query service and I'm using these the code blocks to retrieve database rows via a domain class.

adjustmentCodeList = AdjustmentCode.findAll {
   or {
      ilike('description', "%$filterText%")
      like('id', "%$filterText%")
   }                  
}

adjustmentCodeList = AdjustmentCode.list()

adjustmentCodeList = AdjustmentCode.list(max: count, offset: from)

It works fine actually, but there is a little problem though. It returns the following list (some sensitive data are omitted):

[
   {
      "class": "rvms.maintenance.AdjustmentCode",
      "id": ...,
      "description": ...,
      "lastUpdateBy": ...,
      "lastUpdateDate": ...,
      "status": ...,
      "statusDate": ...,
      "type": ...
   },
   {
      "class": "rvms.maintenance.AdjustmentCode",
      "id": ...,
      "description": ...,
      "lastUpdateBy": ...,
      "lastUpdateDate": ...,
      "status": ...,
      "statusDate": ...,
      "type": ...
   },
    ...
   {
      "class": "rvms.maintenance.AdjustmentCode",
      "id": ...,
      "description": ...,
      "lastUpdateBy": ...,
      "lastUpdateDate": ...,
      "status": ...,
      "statusDate": ...,
      "type": ...
   }
]

It includes the domain class name. How can I remove the class key using some config? My current solution is to manually remove the class key from the list by iterating it inside a loop, removing that key one at a time. But maybe... there is another Grails-ly way.

If you want to see the domain, it looks like this:

package rvms.maintenance

import grails.util.Holders
import groovy.sql.Sql
import oracle.jdbc.OracleTypes
import java.sql.Connection

class AdjustmentCode implements Serializable {
   String id
   String description
   String type
   String status
   Date statusDate
   String lastUpdateBy
   Date lastUpdateDate

   static mapping = {
      table '...'
      version false
      id column : '...'
      description column : '...'
      type column : '...'
      status column : '...'
      statusDate column : '...'
      lastUpdateBy column : '...'
      lastUpdateDate column : '...'
   }

   Map getAdjustmentCodeValues() {
      Map values = [];
      values << [id: this.getId()]
      values << [description: this.getDescription()]
      values << [type: this.getType()]
      values << [status: this.getStatus()]
      values << [statusDate: this.getStatusDate()]
      values << [lastUpdateBy: this.getLastUpdateBy()]
      values << [lastUpdateDate: this.getLastUpdateDate()]

      return values
   }
}

The Grails way to accomplish this is to customize the marshaller. I've explained how to do this with named marshallers in this answer and the same concept applies to your case as well (minus the named portion).
