Question

Does anyone got Deserializer working?

I’m getting complete JSON expression in method deserialize instead of element?

public static void main(String[] args) {
    GsonBuilder gb = new GsonBuilder();
    gb.registerTypeAdapter(DummyObject.class, new JsonSerializer<Date>() {
        public JsonElement serialize(Date src, Type typeOfSrc, 
                         JsonSerializationContext context) {
            System.out.println("serialize...");
            return new JsonPrimitive(DateUtil.toString(src));
        }
    });
    gb.registerTypeAdapter(DummyObject.class, new JsonDeserializer<Date>() {
        DateFormat format = DateFormat.getInstance();
        public Date deserialize(JsonElement json, Type typeOfT, 
                         JsonDeserializationContext context) throws JsonParseException {
            if (!(json instanceof JsonPrimitive)) {
                throw new JsonParseException("The date should be a string value");
            }
            try {
                return format.parse(json.getAsString());
            } catch (ParseException e) {
                throw new JsonParseException(e);
            }
        }
    });
    String jsonExp = "{\"createdDate\":\"2011-12-27T15:21:16\"}";
    Gson g = gb.create();
    DummyObject tf = g.fromJson(jsonExp, DummyObject.class);
}

Gson gson = new GsonBuilder()
.setDateFormat("yyyy-MM-dd'T'HH:mm:ssz")
.create();
