Apache POI PPT - 创建超链接

本章将学习如何在演示文稿中创建超链接。

创建超链接

可以使用 createHyperlink() 方法从 XSLFTextRun 类读取演示文稿中的超链接。按照以下所示步骤在演示文稿中创建超链接。

如以下所示，使用 XMLSlideShow 类创建空演示文稿。−

XMLSlideShow ppt = new XMLSlideShow();

创建空幻灯片并在正文和内容布局中创建文本框和幻灯片正文。

//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向其设置文本，如以下所示 −

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

如以下所示，使用 createHyperlink() 方法从 XSLFTextRun 类创建超链接 −

XSLFHyperlink link = textRun.createHyperlink();

如以下所示，使用 XSLFHyperlink 类的 setAddress() 方法设置超链接的链接地址 −

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

以下是创建演示文稿超链接的完整程序 −

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://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();              
   }
}

将以上 Java 代码保存为 CreatingHyperlinks.java，然后按如下所示从命令提示符处进行编译和执行： −

$javac CreatingHyperlinks.java
$java CreatingHyperlinks

编译并执行可生成以下输出 −

slide created successfully 

在正文中包含超链接的新增幻灯片如下所示 −
