ample.demo;le.gson.Gson;import java.util.HashMap;
import java.util.Map;public class GsonDemo {public static void main(String[] args) {Gson gson = new Gson();String json = "{"name": "Tom", "age": 23}";Map<String, Object> map = gson.fromJson(json, HashMap.class);String name = (("name");Integer age = ((("age")).intValue();System.out.println(name);// TomSystem.out.println(age);// 23}
}

java转json
