fastjson 从jsonArray中获取、遍历jsonObject属性

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');

}

 JSONArray query_rewrite_list = response.getJSONArray("query_rewrite");StringBuffer sb_query = new StringBuffer();StringBuffer sb_score = new StringBuffer();String tagging分词query = "";String tagging分词score = "";// 遍历JSONArray下的JSONObject，以及String类型的value值for (int i = 0; i < query_rewrite_list.size(); i++) {String query_rewrite_extention = response.getJSONArray("query_rewrite").getJSONObject(i).getString("extention");String query_rewrite_level = response.getJSONArray("query_rewrite").getJSONObject(i).getString("level");System.out.println("第" + (i + 1) + "个getJSONObject的extention为" + query_rewrite_extention);System.out.println("第" + (i + 1) + "个getJSONObject的level为" + query_rewrite_level);tagging分词query = sb_query.append(query_rewrite_extention + ",").toString();tagging分词score = sb_score.append(query_rewrite_level + ",").toString();// 单个字段写入-原始query 纠错词qc 类型-第一个卡片的主标题
//                    FileWrite.queryTagging("第" + (i + 1) + "个==" + query + "   " + query_rewrite_n);}// JSONArray下获取所有的JSONObject里的extention，按","拆分打印为一行。StringBuffer可缓存字符串拼接System.out.println("分词数组为" + tagging分词query);// 结果写入queryTagging_log.txt文件FileWrite.queryTagging(query + tagging分词query);FileWrite.queryTagging("======================");FileWrite.queryTagging(query + tagging分词score);

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);}
