如何從大JSON文檔中提取數據？

你可以簡單地通過調用fromJson（）和的toJSON（）該庫的方法試試吧https://sites.google.com/site/gson/gson-user-guide

容易使用谷歌的GSON庫，它將解析Java對象的JSON和JSON對象到Java解析JSON

Gson gson = new Gson(); 

// 1. JSON to Java object, read it from a file. 
Staff staff = gson.fromJson(new FileReader("D:\\file.json"), Staff.class); 

// 2. JSON to Java object, read it from a Json String. 
String jsonInString = "{'name' : 'pravin'}"; 
Staff staff = gson.fromJson(jsonInString, Staff.class); 

// JSON to JsonElement, convert to String later. 
JsonElement json = gson.fromJson(new FileReader("D:\\file.json"), JsonElement.class); 
    String result = gson.toJson(json);
