雷林鹏分享:Apache POI超链接

  本章介绍了如何为超链接添加到内容的单元格。超链接通常被用来访问任何网站的网址,电子邮件或外部文件。

  下面的代码演示如何创建单元格的超链接。

  import java.io.File;

  import java.io.FileOutputStream;

  import org.apache.poi.common.usermodel.Hyperlink;

  import org.apache.poi.hssf.util.HSSFColor;

  import org.apache.poi.ss.usermodel.CreationHelper;

  import org.apache.poi.xssf.usermodel.XSSFCell;

  import org.apache.poi.xssf.usermodel.XSSFCellStyle;

  import org.apache.poi.xssf.usermodel.XSSFFont;

  import org.apache.poi.xssf.usermodel.XSSFHyperlink;

  import org.apache.poi.xssf.usermodel.XSSFSheet;

  import org.apache.poi.xssf.usermodel.XSSFWorkbook;

  public class HyperlinkEX

  {

  public static void main(String[] args) throws Exception

  {

  XSSFWorkbook workbook = new XSSFWorkbook();

  XSSFSheet spreadsheet = workbook

  .createSheet("Hyperlinks");

  XSSFCell cell;

  CreationHelper createHelper = workbook

  .getCreationHelper();

  XSSFCellStyle hlinkstyle = workbook.createCellStyle();

  XSSFFont hlinkfont = workbook.createFont();

  hlinkfont.setUnderline(XSSFFont.U_SINGLE);

  hlinkfont.setColor(HSSFColor.BLUE.index);

  hlinkstyle.setFont(hlinkfont);

  //URL Link

  cell = spreadsheet.createRow(1)

  .createCell((short) 1);

  cell.setCellValue("URL Link");

  XSSFHyperlink link = (XSSFHyperlink)createHelper

  .createHyperlink(Hyperlink.LINK_URL);

  link.setAddress("http://www.manongjc.com/" );

  cell.setHyperlink((XSSFHyperlink) link);

  cell.setCellStyle(hlinkstyle);

  //Hyperlink to a file in the current directory

  cell = spreadsheet.createRow(2)

  .createCell((short) 1);

  cell.setCellValue("File Link");

  link = (XSSFHyperlink)createHelper

  .createHyperlink(Hyperlink.LINK_FILE);

  link.setAddress("cellstyle.xlsx");

  cell.setHyperlink(link);

  cell.setCellStyle(hlinkstyle);

  //e-mail link

  cell = spreadsheet.createRow(3)

  .createCell((short) 1);

  cell.setCellValue("Email Link");

  link = (XSSFHyperlink)createHelper

  .createHyperlink(Hyperlink.LINK_EMAIL);

  link.setAddress(

  "mailto:contact@manongjc.com?"

  +"subject=Hyperlink");

  cell.setHyperlink(link);

  cell.setCellStyle(hlinkstyle);

  FileOutputStream out = new FileOutputStream(

  new File("hyperlink.xlsx"));

  workbook.write(out);

  out.close();

  System.out.println("hyperlink.xlsx written successfully");

  }

  }

  保存上面的代码到文件HyperlinkEX.java。并从命令提示符编译执行它如下。

  $javac HyperlinkEX.java

  $java HyperlinkEX

  它会生成一个名为hyperlink.xlsx在当前目录中的Excel文件并显示在命令提示符处输出:

  hyperlink.xlsx written successfully

  hyperlink.xlsx文件如下所示。
