业务场景：最近在做一个文件路径的加密，很多类设计到文件的路径，由于我们项目的使用的框架比较奇葩，然而很多类继承了一个处理返回参数的父类，我就在这个父类里面开始动刀了： 序列化这边的工具用到的是GSON属于谷歌： 1 import com.alibaba.fastjson.JSONObject; 2 import com.fasterxml.jackson.databind.ObjectMapper; 3 import com.google.gson.*; 4 import com.sxx.inpa.CommonEnctyptUtil; 5 6 import java.io.IOException; 7 import java.lang.reflect.Type; 8 import java.util.*; 9 10 public class GosnDemo { 11 12 public static void main(String[] args) throws IOException { 13 // GsonBuilder用来生成Gson对象. 规定Gson的序列化和返序列化时的格式等内容. 14 GsonBuilder gsonBuilder = new GsonBuilder(); 15 // 这里定义匿名内部类的序列化器

由 孤街浪徒 提交于 2019-12-23 12:34:08
问题 Hee Guys, I'm curious if it is possible to convert a Map to JSON and vica versa with GSON? The object that i'm putting in is already converted to a Object from JSON with GSON.

using GSON to parse and place into a list of objects

由 ε祈祈猫儿з 提交于 2019-12-23 09:27:28
问题 I found this article: http://www.dev-articles.com/article/Google-gson-and-list-of-objects-386003 It looks like it is trying to do what I want, which is parse my json and place them into a List of objects. What I dont get, or maybe the article is missing something, is how the "Project" class gets used. It seems it comes out of nowhere. EDIT: Thanks to yorkw I now have: public static String parseJSONResponse(String jsonResponse) { Type listType = new TypeToken<List<SingleEvent>>(){}.getType();

I currently have a serializer which seems to work and saves the class type for desirialization. I've been using bits of code from this SO post to make the serializer: Gson deserialize interface to its Class implementation This is the JSON I'm working with: [ {
