Grails LazyMap to POJO Conversion failed due to Date value

Question

I am using Grails 2.4 and jersey request builder plug-in.

I am getting below error on

def resRequestList = RESPONSE FROM REST REQUEST
ResourceTest item1 = resRequestList.get(0)

error is

Cannot cast object '{createdBy=2576, endDate=10-Jun-2016, id=14}'
with class 'groovy.json.internal.LazyMap' to class 'com.modal.resource.ResourceTest' 

due to: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '10-Jun-2016' with class 'java.lang.String' to class 'java.util.Date'

It looks like conversion failed from Sting to Date.

I needs solution to map it automatically to POJO without string to date conversation error.

There should be anything which do preprocessing before casting.

Please Help.

You can add @BindingFormat('dd-MMM-yyyy') annotation to your date field in ResourceTest class. You can also use grails.databinding.dateFormats config option to set default, global binding format. See this answer for details: Binding a Grails date from params in a controller.

I would also recommend not to send month as Jun as this is locale specific and may not work dependning on your environment.

Hi droggo. Thanks for reply, My ResourceTest class is POJO not POGO. How do i add @BindingFormat('dd-MMM-yyyy') in POJO class. – Hardik Patel Jun 21 '16 at 06:43

Finally I find alternate solution which is best fit to me.

I have used reflection to get original List of Object using GenericType.

My Code is as below

def resRequestList = clientResponse.getEntity(new GenericType<ArrayList<ResourceTest>>(){});
