Alibaba fastjson 从jsonArray中获取jsonObject属性值

1.json字符串转jsonArray

JSONArray json  = JSONArray.parseArray(json_String);

2.jsonArray到jsonObject的转换

  for (int i = 0; i < jsonArray.size(); i++){row = sheet.createRow(num++);JSONObject object = (JSONObject) jsonArray.get(i);object.getString('属性');}

3.jsonObject到jsonArray的转换

 JSONArray seconddataArray = object.getJSONArray("jsonArray的key");for (int x = 0; x < seconddataArray.size(); x++){JSONObject seconddata = (JSONObject) seconddataArray.get(x);}
