java - Can jackson deserialize from different JSON string to same object? -

-

i have json string, this:

{ ... "token": "abc123" ... }

then reason, have update new structure, expected incoming json string becomes:

{ ... "token": {"property01":"true", "property02":"false", "value": "abc123"} ... }

originally, token field in string type, now, becomes object, additional properties.

i need handle both format backward compatibility, can jackson handle case?

you creating own deserializer:

class foojsondeserializer extends jsondeserializer<foo> {      @override     public foo deserialize(jsonparser jp, deserializationcontext ctxt) throws ioexception, jsonprocessingexception {         foo foo = new foo();         //deserialize data here         return foo;     } }

and don't forget add deserializer class

@jsondeserialize(using = foojsondeserializer.class) class foo {     ... }
