Grails(15)How to Customized Marshaller

Grails(15)How to Customized Marshaller
SOAPUI eclipse plugin URL
http://www.soapui.org/eclipse/update

Use the POSTMAN in chrome to test the REST API

We can create the Marshaller class especially for one class

package com.sillycat.project.util.marshaller

import grails.converters.JSON

import org.codehaus.groovy.grails.web.converters.exceptions.ConverterException
import org.codehaus.groovy.grails.web.converters.marshaller.ObjectMarshaller
import org.codehaus.groovy.grails.web.json.JSONWriter

import com.sillycat.project.Store
import com.sillycat.project.util.Util

class StoreJSONMarshaller implements ObjectMarshaller<JSON> {

publicboolean supports(Object object) {
     if(object instanceof Store){
          return true;
     }
     return false;
}

publicvoid marshalObject(Object object, JSON converter)
throws ConverterException {
     def store = (Store)object
     JSONWriter writer = converter.getWriter();

     writer.object();

     def streetAddress = (store.address2 == null || store.address2.equals("")) ? store.address1 : store.address1 + ' ' + store.address2
     writer.key("address")
     writer.value([
          'state':store.state,
          'country': store.country,
          'streetAddress': streetAddress,
          city: store.city,
          postalCode: store.zip
     ])

     writer.key("id")
     writer.value(store.getId())

     writer.key("name")
     writer.value(store.storeName)

     writer.key("status")
     writer.value(store.enabled?'ENABLED':'DISABLED')

     writer.key("retailerStoreId")
     writer.value(store.storeCode)

     writer.key("geofences")

     def latitude = null;
     def longitude = null;

     if(store.geoFence != null && store.geoFence.center != null){
          latitude =  store.geoFence.center.latitude;
     }

     if(store.geoFence != null && store.geoFence.center != null){
          longitude = store.geoFence.center.longitude
     }

     writer.value([
          name: store.storeName,
          id: store.geoFence.id,
          type: "STORE",
          latitude: latitude,
          longitude: longitude,
          radius: store.geoFence.radius,
          ssid : store.ssid,
          bssid: store.bssid
     ])

     def brandCode = null
     //if(Util.getCurrentBrand() != null){
     //brandCode = Util.getCurrentBrand().getCode()
     //}
     //writer.key("brandCode")
     //writer.value(brandCode)

     writer.key("timezone")
     writer.value(store.timeZone == null ? null : store.timeZone.getID())

     writer.endObject();
     }
}

Here comes the test class:
@Test
publicvoid testGetSuccess() {
List<Store> stores = [
  new Store(storeCode:"TS1",storeName:"Test Store 1",enabled:true),
  new Store(storeCode:"TS2",storeName:"Test Store 2",enabled:true),
  new Store(storeCode:"TS3",storeName:"Test Store 3",enabled:false)]

mockDomain(Store, stores)

JSON.registerObjectMarshaller(new StoreJSONMarshaller(), 1)
registerMetaClass(Util)

def controller = new StoreController()
controller.params.id = 1
controller.apiGet()

assertEquals(controller.response.status, 200)
//System.out.println(controller.response.status)
//System.out.println(controller.response.contentAsString)

def actualStore = JSON.parse(controller.response.contentAsString)

assertNotNull(actualStore)
assertEquals("Test Store 1",actualStore.name)
}

In the configuration file, BootStrap.groovy
bootstrapService.registerCustomJSONMarshallers()

And here is the class BootstrapService.groovy

import grails.converters.JSON

import com.sillycat.project.util.marshaller.StoreJSONMarshaller

class BootstrapService {

static transactional = true

void registerCustomJSONMarshallers() {
  JSON.registerObjectMarshaller(new StoreJSONMarshaller(), 1)
}
}
