json数据格式

{
  "list": [
    {
      "ann_type_name": "邮件", 
      "anne_name": "plugin.png", 
      "anne_path": "/jscdc/upload/eamil/plugin.png", 
      "userid": "11e4-e6a3-4bcea910-a76f-9f966c0d602a"
    }, 
    {
      "ann_type_name": "邮件", 
      "anne_name": "act_6.gif", 
      "anne_path": "/jscdc/upload/eamil/act_6.gif", 
      "userid": "11e4-e6a3-4bcea910-a76f-9f966c0d602a"

			JSONObject jsonObject = JSONObject.fromObject(string); //把json格式的字符串，转换成json对象
			//String reString = (String) jsonObject.get("arg1");
			JSONArray jsonArray = jsonObject.getJSONArray("list");  //取出json对象里面“root”数组，并转换成JSONArray对象
			Iterator<JSONArray> itr = jsonArray.iterator();  //迭代jsonArray
			while(itr.hasNext()) {
