谷歌的Gson.jar:

//list转换为json
Gson gson = new Gson();  
List persons = new ArrayList();  
String str = gson.toJson(persons);  

//json转换为list
Gson gson = new Gson();  
List persons = gson.fromJson(str, new TypeToken>(){}.getType());  

• 阿里的fastJson.jar：

//list转换为json
List list = new ArrayList();
String str=JSON.toJSON(list).toString();

//json转换为list
  List list = new ArrayList();  
        list = JSONObject.parseArray(jasonArray, Person.class);
