json - Custom Deserialization using Jackson in Java -

i trying implement university project try fetch values 2 json fields , map 1 pojo class.

sample json:

"event":[{"d17-32":0,"s10":"d"}] 

pojo class

    public class event {     @jsondeserialize(using = signalcustomdeserializer.class)     @jsontypeinfo(use = jsontypeinfo.id.none)     @jsonproperty("s10")     private signal s10;      @jsonproperty("d17-32")     private string d17_32;     //getter , setter implementation     } 

class need serialize fields

    public class signal{         private string value;        private string detectorid;         private int detectorvalue; //this value has fetched json       //getter , setter implementation     } 

custom deserializer class

    public class signalcustomdeserializer extends jsondeserializer {         @override         public signal deserialize(jsonparser jsonparser, deserializationcontext deserializationcontext) throws ioexception, jsonprocessingexception {           string signalid = jsonparser.getcurrentname();           string signalval = jsonparser.getvalueasstring();           string detectorval = jsonparser.getvalueasstring("d01-16");           signal signal = new signal();           signal.setvalue(signalval);           signal.setdetectorid(getdetectorid(signalid));           return signal;        }     } 

i able signalid , signalvalue unable value other field. unsure if available in jsonobject when custom deserialization class called.
