本章说明如何向单元格中的内容添加超链接。通常,超链接用于访问任何Web URL,电子邮件或外部文件。
以下代码显示了如何在单元格上创建超链接。
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.tutorialspoint.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:?" + "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");
}
}
将上面的代码另存为HyperlinkEX.java 。如下从命令提示符编译并执行它。
$javac HyperlinkEX.java
$java HyperlinkEX
它将在当前目录中生成一个名为超链接.xlsx的Excel文件,并在命令提示符下显示以下输出。
hyperlink.xlsx written successfully
超链接.xlsx文件如下所示。
