deserialization - 适用于java.util.Date的Gson反序列化器

Question

有人让Deserializer工作吗？我正在方法“反序列化”而不是元素中获得完整的JSON表达式？

    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();
