fastjson的jsonObject-jsonArray处理

1 String jsonstr = "[{\"id\":\"123\",\"name\":\"张三\",\"age\":\"11\"},{\"id\":\"321\", \"name\":\"李四\",\"age\":\"21\"}]";
2 JSONArray jsonArray = JSONArray.parseArray(jsonstr);
3 for (int i=0;i<jsonArray.size();i++) {//会循环两次
4     JSONObject jsonObject = jsonArray.getJSONObject(i);
5     String id = jsonObject.getString("id");//123,321
6     String name = jsonObject.getString("name");//张三,李四
7     String age = jsonObject.getString("age");//11,21
8 }
