Apache POI PPT - Creating Hyperlinks

在本章中，你将学习如何在演示文稿中创建超链接。

Creating Hyperlinks

你可以使用 XSLFTextRun 类的 createHyperlink() 方法来读取演示文稿中的超链接。按照下面给出的步骤，在演示文稿中创建一个超链接。

使用 XMLSlideShow 类创建一个空演示文稿，如下所示：

XMLSlideShow ppt = new XMLSlideShow();

创建一个空幻灯片，并使用主体和内容布局创建一个文本框和幻灯片的正文。

//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();

创建文本运行对象，并设置其文本，如下所示：

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

使用 XSLFTextRun 类的 createHyperlink() 方法创建一个超链接，如下所示：

XSLFHyperlink link = textRun.createHyperlink();

使用 XSLFHyperlink 类的 setAddress() 方法设置超链接的链接地址，如下所示：

link.setAddress("https://www.tutorialspoint.com/");

下面给出了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().get(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("Tutorials point");

      //creating the hyperlink
      XSLFHyperlink link = textRun.createHyperlink();

      //setting the link address
      link.setAddress("https://www.tutorialspoint.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 created 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，如下所示：

$javac CreatingHyperlinks.java
$java CreatingHyperlinks

它将编译和执行以生成以下输出 −

slide created successfully

新添加的幻灯片及其正文中的超链接如下所示：
