json数组怎样导出到Excel

本篇文章给大家分享的是有关json数组怎样导出到Excel，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。

导出方法

public static JSONObject createExcel(String src, JSONArray json) {         //用于返回响应的消息         JSONObject result = new JSONObject();         try {             File file = new File(src);             file.createNewFile();             OutputStream outputStream = new FileOutputStream(file);             WritableWorkbook writableWorkbook = Workbook.createWorkbook(outputStream);             WritableSheet sheet = writableWorkbook.createSheet("First sheet", 0);             //设置边框             WritableFont font = new WritableFont(WritableFont.TIMES, 10, WritableFont.NO_BOLD, false);             WritableCellFormat format = new WritableCellFormat(font);             format.setBorder(jxl.format.Border.ALL, BorderLineStyle.THIN);             format.setAlignment(Alignment.CENTRE);             JSONArray jsonArray = json;             Label label;//单元格对象             int column = 0;//列数计数             JSONObject first = jsonArray.getJSONObject(0);             Iterator<String> iterator = first.keys();             while (iterator.hasNext()) {                 String key = iterator.next();                 label = new Label(column++, 0, key, format);                 sheet.addCell(label);             }             for (int i = 0; i < jsonArray.size(); i++) {                 JSONObject item = jsonArray.getJSONObject(i);                 iterator = item.keys();                 column = 0;                 while (iterator.hasNext()) {                     String key = iterator.next();                     String value = item.getString(key);                     label = new Label(column++, (i + 1), value, format);                     sheet.addCell(label);                 }             }             writableWorkbook.write();             writableWorkbook.close();         } catch (Exception e) {             result.put("result", "failed");             result.put("reason", e.getMessage());             return result;         }         result.put("result", "successed");         return result;     }

测试方法

public static void main(String[] args) {         String src = "C:\\a.xls";         String str = "[{\"dupCount\":4,\"qs_sumValue\":30,\"qs_span\":16,\"qs_dupCount\":0,\"sumValue\":64,\"dxb\":\"2:6\",\"job_qs\":\"2:1\",\"winNumber\":\"19 03 08 06 12 01 05 10\",\"zhb\":\"4:4\",\"matchNo\":\"17122387\",\"zhb_qs\":\"2:1\",\"job\":\"4:4\",\"dxb_qs\":\"1:2\",\"span\":18},{\"dupCount\":4,\"qs_sumValue\":36,\"qs_span\":14,\"qs_dupCount\":1,\"sumValue\":70,\"dxb\":\"3:5\",\"job_qs\":\"0:3\",\"winNumber\":\"20 10 06 11 15 01 02 05\",\"zhb\":\"4:4\",\"matchNo\":\"17122386\",\"zhb_qs\":\"0:3\",\"job\":\"4:4\",\"dxb_qs\":\"1:2\",\"span\":19},{\"dupCount\":5,\"qs_sumValue\":32,\"qs_span\":13,\"qs_dupCount\":0,\"sumValue\":57,\"dxb\":\"1:7\",\"job_qs\":\"2:1\",\"winNumber\":\"19 07 06 10 01 02 03 09\",\"zhb\":\"5:3\",\"matchNo\":\"17122385\",\"zhb_qs\":\"2:1\",\"job\":\"5:3\",\"dxb_qs\":\"1:2\",\"span\":18},{\"dupCount\":6,\"qs_sumValue\":15,\"qs_span\":10,\"qs_dupCount\":1,\"sumValue\":46,\"dxb\":\"1:7\",\"job_qs\":\"3:0\",\"winNumber\":\"11 01 03 08 10 02 05 06\",\"zhb\":\"5:3\",\"matchNo\":\"17122384\",\"zhb_qs\":\"3:0\",\"job\":\"4:4\",\"dxb_qs\":\"1:2\",\"span\":10},{\"dupCount\":0,\"qs_sumValue\":27,\"qs_span\":5,\"qs_dupCount\":0,\"sumValue\":46,\"dxb\":\"1:7\",\"job_qs\":\"1:2\",\"winNumber\":\"10 11 06 04 05 01 02 07\",\"zhb\":\"5:3\",\"matchNo\":\"17122383\",\"zhb_qs\":\"1:2\",\"job\":\"4:4\",\"dxb_qs\":\"1:2\",\"span\":10}]";         JSONArray jsonArray = JSONArray.fromObject(str);         JSONObject jsonObject1 = createExcel(src, jsonArray);         if (!JSONUtils.isNull(jsonObject1.get("result"))) {             String result = jsonObject1.get("result").toString();             if ("failed".equals(result)) {                 System.out.println(jsonObject1.get("reason"));             }         }     }
