兔子--java服务器端把对象列表转化为jsonarray

          List     list = new ArrayList<Person>();
list = 通过查询数据库，查出数据;
// 把list转化为jsonArray
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
try {
JSONObject object = new JSONObject();
object.put("id", list.get(i).getId());
object.put("name", list.get(i).getName());
object.put("age", list.get(i).getAge()); 
array.put(object);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
pw.write(array.toString());
