介绍

1.编写一个方法，传入JSONArray 

2.如果是list数据同样道理

3.通过传入的数据进行遍历

4.创建对应的文件

5.创建对应的excel，的行

6.创建行的列内容

7.写入表头

8.写入每一个单元内容

9.校验信息

10.直接用最后的完整文件

创建文件夹

  String tempFileDir = "D:/test/09874/";
      File parentFileDir = new File(tempFileDir);
      if (!parentFileDir.exists()) {
        parentFileDir.mkdirs();
      }
      String uploadFile = tempFileDir+"视频网站数据xx.xlsx";

1.创建方法

2.添加传入值

3.可以扩展添加生成文件地址和生成文件名

4.校验文件夹是否纯在，不纯在，创建，防止应为没有文件夹报错

打开文件

String uploadFile = tempFileDir+"视频网站数据xx.xlsx";
      OutputStream fos = new FileOutputStream(uploadFile);
      XSSFWorkbook workBook = new XSSFWorkbook();
      XSSFSheet sheet = workBook.createSheet();

      XSSFRow row = null;
      XSSFCell cell = null;

创建表头

//表头 
      row = sheet.createRow(0);
      String[] names = { "序号", "页面地址", "视频名称" , "上传时间", "视频时长","上传作者主页地址","视频网站地址","视频网站名称"};
      for (int index = 0; index < 8; index++) {
        cell = row.createCell(index);
        cell.setCellValue(names[index]);
      }
      

写入表内容数据

//表数据
      for (int i = 0; i < ja.size(); i++) {
        String[] zf = ja.getString(i).split(",__,");
        
        row = sheet.createRow(i+1);//创建行
        
        cell = row.createCell(0);//序号
        cell.setCellValue(i+1);
        
        cell = row.createCell(1);//内容
        cell.setCellValue(zf[0]);
        
        cell = row.createCell(2);
        cell.setCellValue(zf[1]);
        
        cell = row.createCell(3);
        cell.setCellValue(zf[2]);
        
        cell = row.createCell(4);
        cell.setCellValue(zf[3]);
        
        cell = row.createCell(5);
        cell.setCellValue(zf[4]);
        
        cell = row.createCell(6);
        cell.setCellValue(zf[5]);
        
        cell = row.createCell(7);
        cell.setCellValue(zf[6]);
         
      }
      workBook.write(fos);

        cell = row.createCell(0);//序号
        cell.setCellValue(i+1);
        
        cell = row.createCell(1);//内容
        cell.setCellValue(zf[0]);
        
        cell = row.createCell(2);
        cell.setCellValue(zf[1]);
        
        cell = row.createCell(3);
        cell.setCellValue(zf[2]);
        
        cell = row.createCell(4);
        cell.setCellValue(zf[3]);
        
        cell = row.createCell(5);
        cell.setCellValue(zf[4]);
        
        cell = row.createCell(6);
        cell.setCellValue(zf[5]);
        
        cell = row.createCell(7);
        cell.setCellValue(zf[6]);
         
      }
      workBook.write(fos);
    } catch (Exception e) {
      e.printStackTrace();
      System.out.println(e.toString());
    }
  }

 介绍

1.从上往下可以进行自行扩展

2.主要重点就在于创建文件

3.文件字段位置

4.位置对应上即可
