<em>POI</em>列总计，我想利用Java中<em>POI</em>

//设置超链接就可以了，可以参考下面的代码

//如何设置超链接

 

 HSSFWorkbook wb = new HSSFWorkbook();

//超链接的单元格风格

   //超链接默认的是蓝色底边框

   HSSFCellStyle hlink_style = wb.createCellStyle();

   HSSFFont hlink_font = wb.createFont();

   hlink_font.setUnderline(HSSFFont.U_SINGLE);

   hlink_font.setColor(HSSFColor.BLUE.index);

   hlink_style.setFont(hlink_font);

HSSFCell cell;

   HSSFSheet sheet = wb.createSheet("Hyperlinks");

//URL

   cell = sheet.createRow(0).createCell((short)0);

   cell.setCellValue("URL Link");

   HSSFHyperlink link = new HSSFHyperlink(HSSFHyperlink.LINK_URL);

   link.setAddress("");

   cell.setHyperlink(link);

   cell.setCellStyle(hlink_style);

//链接到当前路径的一个7a64e4b893e5b19e334文件

   cell = sheet.createRow(1).createCell((short)0);

   cell.setCellValue("File Link");

   link = new HSSFHyperlink(HSSFHyperlink.LINK_FILE);

   link.setAddress("link1.xls");

   cell.setHyperlink(link);

   cell.setCellStyle(hlink_style);

//链接到e-mail

   cell = sheet.createRow(2).createCell((short)0);

   cell.setCellValue("Email Link");

   link = new HSSFHyperlink(HSSFHyperlink.LINK_EMAIL);

   //note, if subject contains white spaces, make sure they are url-encoded

   link.setAddress("mailto:?subject=Hyperlinks");

   cell.setHyperlink(link);

   cell.setCellStyle(hlink_style);

//链接到 workbook的某个地方

//创建一个目标Sheet和单元格

   HSSFSheet sheet2 = wb.createSheet("Target Sheet");

   sheet2.createRow(0).createCell((short)0).setCellValue("Target Cell");

cell = sheet.createRow(3).createCell((short)0);

   cell.setCellValue("Worksheet Link");

   link = new HSSFHyperlink(HSSFHyperlink.LINK_DOCUMENT);

   link.setAddress("'Target Sheet'!A1");

   cell.setHyperlink(link);

   cell.setCellStyle(hlink_style);

FileOutputStream out = new FileOutputStream("c://hssf-links.xls");

   wb.write(out);

   out.close();

我感觉你也可以在后端计算出结果传递到前端拼接出来呀

代码：

HSSFWorkbook wb = new HSSFWorkbook();HSSFSheet sheet = wb.createSheet();ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();BufferedImage bufferImg = ImageIO.read(new File("D:\\fruit.PNG"));ImageIO.write(bufferImg,"PNG",byteArrayOut);HSSFClientAnchor anchor = new HSSFClientAnchor(5,0,500,122,(short) 0, 5,(short)10,15); HSSFPatriarch patri = sheet.createDrawingPatriarch();patri.createPicture(anchor , wb.addPicture(byteArrayOut.toByteArray(), HSSFWorkbook.PICTURE_TYPE_PNG)); ByteArrayOutputStream outStream = new ByteArrayOutputStream();wb.write(outStream);

上面代码只是大概，但需要用到的类都已经列出。接下来需要做的就是把 outStream输出到excel文件中去了。

具体的类的document可以去下面网站上查看:
