Java Gson

gson.fromJson(String json, Class classOfT)

一次轉換一個Object:

import com.google.gson.Gson;

Gson gson = new Gson();
String json = "{"Id":"A123", "Name":"Bob"}";
SomePerson personObj = gson.fromJson(json, SomePerson.class);

class SomePerson {
    String Id;
    String Name;
}

gson.fromJson(String json, Type typeOfT)

一次轉換多個Object:

import java.lang.reflect.Type;

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;

Gson gson = new Gson();
String json = "[
    {"Id":"A001", "Name":"Bob"},
    {"Id":"A002", "Name":"Ken"}
]";
Type listType = new TypeToken<ArrayList<SomePerson>>() {}.getType();
List<SomePerson> personObjList = gson.fromJson(json, listType);

class SomePerson {
    String Id;
    String Name;
}
