poi操作execl如何在cell里做一个超链接访问当前路径文件夹或文件

求例子。。。

[code="java"]
这个是设置一个超链接弹出email地址, 其他类似
import java.io.FileOutputStream;

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

/**

  public class HyperlinkExample {

  public static void main(String[]args) throws Exception{
  Workbook wb = new XSSFWorkbook(); //or new HSSFWorkbook();
  CreationHelper createHelper = wb.getCreationHelper();

  CellStyle hlink_style = wb.createCellStyle();
  Font hlink_font = wb.createFont();
  hlink_font.setUnderline(Font.U_SINGLE);
  hlink_font.setColor(IndexedColors.BLUE.getIndex());
  hlink_style.setFont(hlink_font);

  Cell cell;
  Sheet sheet = wb.createSheet("Hyperlinks");
  //URL
  cell = sheet.createRow(0).createCell((short)0);
  cell.setCellValue("URL Link");

  Hyperlink link = createHelper.createHyperlink(Hyperlink.LINK_URL);
  link.setAddress("http://poi.apache.org/");
  cell.setHyperlink(link);
  cell.setCellStyle(hlink_style);

  //link to a file in the current directory
  cell = sheet.createRow(1).createCell((short)0);
  cell.setCellValue("File Link");
  link = createHelper.createHyperlink(Hyperlink.LINK_FILE);
  link.setAddress("link1.xls");
  cell.setHyperlink(link);
  cell.setCellStyle(hlink_style);

  //e-mail link
  cell = sheet.createRow(2).createCell((short)0);
  cell.setCellValue("Email Link");
  link = createHelper.createHyperlink(Hyperlink.LINK_EMAIL);
  //设置路径
  link.setAddress("mailto:poi@apache.org?subject=Hyperlinks");
  cell.setHyperlink(link);
  cell.setCellStyle(hlink_style);

  //create a target sheet and cell
  Sheet 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");
  Hyperlink link2 = createHelper.createHyperlink(Hyperlink.LINK_DOCUMENT);
  link2.setAddress("'Target Sheet'!A1");
  cell.setHyperlink(link2);
  cell.setCellStyle(hlink_style);

  FileOutputStream out = new FileOutputStream("hyperinks.xlsx");
  wb.write(out);
  out.close();

  }
  }
