JSON字符串和list集合互转

谷歌的Gson.jar：

//list转换为json

Gson gson = new Gson();

List<Person> persons = new ArrayList<Person>();

String str = gson.toJson(persons);

//json转换为list

Gson gson = new Gson();

List<Person> persons = gson.fromJson(str, new TypeToken<List<Person>>(){}.getType());

阿里的fastJson.jar：

//list转换为json字符串

List<CustPhone> list = new ArrayList<CustPhone>();

String str=JSON.toJSON(list).toString();

//json字符串转换为list

List<Person> list = new ArrayList<Person>();

list = JSONObject.parseArray(String str, Person.class);
