以下是使用Java向单元格内容添加超链接的程序。

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 AddHyperlinkToCell {
   public static void main(String[] args) throws Exception {
      //Create a Workbook
      XSSFWorkbook workbook = new XSSFWorkbook();
      //Create a Spread Sheet
      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("https://www.xnip.cn/" );
      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@xnip.cn?subject=Hyperlink");
      cell.setHyperlink(link);
      cell.setCellStyle(hlinkstyle);
      FileOutputStream out = new FileOutputStream(
         new File("C:/poiexcel/addHyperlink.xlsx"));
      //Writing the content
      workbook.write(out);
      out.close();
      System.out.println("hyperlink.xlsx written successfully");
   }
}
