有两种方法实现:
(1)直接转换:
创建JSONArray对象、JSONObject对象,通过put方法将其数据以键值对的形式填充,如例:
//假如有一个Java实体类Person, 包括以下属性: Telefon, Geschlecht, Verheiratet, Adresse.
ArrayList
for (int i = 0; i
persons.add(new Person("138******67", "女", true, "北京朝阳区"));//填充Java实体类集合
}
JSONArray array = new JSONArray();// Json格式的数组形式
JSONObject obj;//json格式的单个对象形式
for (int i = 0; i
obj = neues JSONObject();
//依次填充每一个Java实体对象
versuchen {
obj.put("phone", personen.get(i).getPhone());//json通过put方式以key-value形式填充
obj.put("sex", personen.get(i).getSex());
obj.put("married", personen.get(i).getMarried());
obj.put("address", personen.get(i).getAddress());
array.put(obj);//JSONObject verwendet JSONArray
} Catch (JSONException e) {
e.printStackTrace();
}
}
(2)通过GSON工具实现:
只需要创建GSON对象,通过toJson方法转换即可。如例:
//模拟Java数据
Person person = neue Person("敏敏", 23, "女", "北京市海淀区);
//创建GSON对象
Gson gson = new Gson();
//调用toJson方法即可转换为字符串的json格式
String json = gson.toJson(person);
