用Gson 实体类转换ZonedDateTime类型

实体类直接转换会报错，所以需要特别转换：

Gson gson=new GsonBuilder().registerTypeAdapter(ZonedDateTime.class,new JsonDeserializer<ZonedDateTime>(){
	@Override
    public ZonedDateTime deserialize(JsonElement jsonElement, Type type, JsonDeserializationContext jsonDeserializationContext) throws JsonParseException {
								return ZonedDateTime.parse(jsonElement.getAsJsonPrimitive().getAsString());
							}
 						}).create();
					return gson.fromJson(result,OrderDigestInfoResp.class);
