反序列化 – 用于java.util.Date的Gson Deserializer

有人有Deserializer工作吗？我在方法“deserialize”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);

}

解决方法

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