解决方案

     GsonBuilder builder = new GsonBuilder();

        // Register an adapter to manage the date types as long values
        builder.registerTypeAdapter(Date.class, new JsonDeserializer<Date>() {
            public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
                return new Date(json.getAsJsonPrimitive().getAsLong());
            }
        });

        Gson gson = builder.create();
