Converting json to java where a field is of interface Type

Question

I have a JSON like

{
   "age" : "35",
   "otherdetails":{
   "address" : "xyx",
    "pincode" : "978897"
    }
}

I have a base class to covert JSON TO JAVA

 class Base
 {
     int age;
     OtherDetails otherdetails;
 }

also i have an interface for otherdetails and a class implementing the interface

interface OtherDetails
class AddressDetails extends OtherDetails
{
   String address;
   String pincode;
}

How can i use gson or jackson to convert the json so that it picksup AddressDetails class when converting thee otherdetails attribute?

So what happens here? is values are null or is it gives you an exception ? — Vimukthi, Jul 08 '19 at 08:03

The solution was to add a new attribute in my json like classname in which i populate the correct classname eg AdressDetail. Then at the interface level i had to add annotation with the classname attribute – tushar singhal Jul 08 '19 at 12:41
