不要自己折騰去亂半天，保證自己的數據格式對的情況下直接用Google和Alibaba的jar

谷歌的Gson.jar:

//list轉換為json Gson gson = new Gson(); List<Person> persons = new ArrayList<Person>(); String str = gson.toJson(persons); //list轉換為json List<CustPhone> list = new ArrayList<CustPhone>(); String str=JSON.toJSON(list).toString();

阿里的fastJson.jar：

//list轉換為json List<CustPhone> list = new ArrayList<CustPhone>(); String str=JSON.toJSON(list).toString();//json轉換為listList<Person> list = new ArrayList<Person>(); list = JSONObject.parseArray(jasonArray, Person.class);

得到的數據

[{"fullName":"sdfsf","id":11},{"fullName":"sdfsfs","id":12},{"fullName":"sdfsf","id":13},{"fullName":"dsfasfs","id":14},{"fullName":"dsfasfs","id":15},{"fullName":"dsfasfs","id":16},{"fullName":"dsfasfs","id":17},{"fullName":"dsfasfs","id":18},{"fullName":"dsfasfs","id":19},{"fullName":"dsfasfs","id":20},{"fullName":"dsfasfs","id":21}]

在maven之下簡直無煩惱
