导入jar包直接调用,简单粗暴无烦恼!
jar文件:http://files.cnblogs.com/files/huanglibin/%E6%AD%8C%E7%9A%84Gson.jar%E5%92%8C%E9%98%BF%E9%87%8C%E7%9A%84fastJson.jar.rar
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
List<CustPhone> list = new ArrayList<CustPhone>();
String str=JSON.toJSON(list).toString();
//json转换为list
List<Person> list = new ArrayList<Person>();
list = JSONObject.parseArray(jasonArray, Person.class);
