java后台存入json对象:
/** * 根据卡内码得到最近的租还车记录 * 返回json对象 * @param cardInNo * @return */ public String getRefInfo(String cardInNo) { StringBuffer bf=new StringBuffer(1024); bf.append("");//sql语句 System.out.println(bf.toString()); /************ 存储json对象***************/ List<JSONObject> jsonList=new ArrayList<JSONObject>(); try { /****************获得判断信息存入数组中*******************/ String [][] str=getArrayByName(bf.toString()); if(str!=null){ for (int i = 0; i < str[0].length; i++) { JSONObject returnValue =new JSONObject(); returnValue.put("a", str[0][i]) .put("b", str[1][i]) .put("c", str[2][i].trim().equals("")?"":str[2][i].substring(0, 19)) .put("d", str[3][i].trim().equals("")?"":str[3][i].substring(0, 19)) .put("e", str[4][i]) .put("f", str[5][i]) .put("g", str[6][i]) .put("h", str[7][i]) .put("i", str[8][i]); jsonList.add(returnValue); } } }catch (Exception e) { e.printStackTrace(); } System.out.println(jsonList.toString()); return jsonList.toString(); }
