Thrift to Json with Field filter

gistfile1.java

//Solution to convert thrift to pojo to send back to client
// only some fields
public List<JsonObject> mapping(List<TBase> listThrift){
      TSerializer serializer = new TSerializer(new TSimpleJSONProtocol.Factory());
      ObjectMapper mapper = new ObjectMapper();
      for(TBase f : listThrift) {
            myJsonList.add(mapper.readValue(serializer.toString(f), MyJsonJson.class));
      }
      return myJsonList;
}
//JsonObject contains the same wanted fields as my Tbase object 

//Solution 2
public class JsonObject {
      public JsonObject(MyTBase myTBase){
            this.id = myTBase.id;
            this.name = myTBase.name;
            this.field = myTBase.field;
      }
