创建超链接（ Creating Hyperlinks）

在本章中，您将学习如何在演示文稿中创建超链接。

创建超链接

您可以使用XSLFTextRun类的createHyperlink()方法读取演示文稿中的超链接。 按照下面给出的步骤在演示文稿中创建超链接。

使用XMLSlideShow类创建一个空的演示文稿，如下所示 -

XMLSlideShow ppt = new XMLSlideShow();

创建一个空幻灯片，并使用正文和内容布局创建幻灯片的文本框和正文。

//create an empty presentation
XSLFSlideMaster slideMaster = ppt.getSlideMasters()[0];
//creating a slide with title and content layout
XSLFSlideLayout slidelayout = slideMaster.getLayout(SlideLayout.TITLE_AND_CONTENT);
XSLFSlide slide = ppt.createSlide(slidelayout);
//selection of body place holder
XSLFTextShape body = slide.getPlaceholder(1);
//clear the existing text in the slide
body.clearText();

创建一个文本运行对象并将文本设置为它，如下所示 -

XSLFTextRun textRun = body.addNewTextParagraph().addNewTextRun();
textRun.setText("IOWIKI");

使用XSLFTextRun类的createHyperlink()方法创建超链接，如下所示 -

XSLFHyperlink link = textRun.createHyperlink();

使用XSLFHyperlink类的setAddress()方法将链接地址设置为超链接，如下所示 -

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

以下是在演示文稿中创建超链接的完整程序 -

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.xslf.usermodel.SlideLayout;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFHyperlink;
import org.apache.poi.xslf.usermodel.XSLFSlide;
import org.apache.poi.xslf.usermodel.XSLFSlideLayout;
import org.apache.poi.xslf.usermodel.XSLFSlideMaster;
import org.apache.poi.xslf.usermodel.XSLFTextRun;
import org.apache.poi.xslf.usermodel.XSLFTextShape;
public class CreatingHyperlinks {
   public static void main(String args[]) throws IOException {
      //create an empty presentation
      XMLSlideShow ppt = new XMLSlideShow();
      //getting the slide master object
      XSLFSlideMaster slideMaster = ppt.getSlideMasters()[0];
      //select a layout from specified list
      XSLFSlideLayout slidelayout = slideMaster.getLayout(SlideLayout.TITLE_AND_CONTENT);
      //creating a slide with title and content layout
      XSLFSlide slide = ppt.createSlide(slidelayout);
      //selection of title place holder
      XSLFTextShape body = slide.getPlaceholder(1);
      //clear the existing text in the slid
      body.clearText();
      //adding new paragraph
      XSLFTextRun textRun = body.addNewTextParagraph().addNewTextRun();
      //setting the text
      textRun.setText("IOWIKI");	
      //creating the hyperlink
      XSLFHyperlink link = textRun.createHyperlink();
      //setting the link address
      link.setAddress("http://www.iowiki.com/");
      //create the file object            
      File file = new File("hyperlink.pptx");
      FileOutputStream out = new FileOutputStream(file);
      //save the changes in a file
      ppt.write(out);
      System.out.println("slide cretated successfully");
      out.close();              
   }
}

将上述Java代码保存为CreatingHyperlinks.java ，然后从命令提示符编译并执行它，如下所示 -

$javac CreatingHyperlinks.java
$java CreatingHyperlinks

它将编译并执行以生成以下输出 -

slide cretated successfully 

新添加的幻灯片在其正文中带有超链接，如下所示 -
