Apache POI PPT - 創(chuàng)建超鏈接

在本章中，您將學(xué)習(xí)如何在演示文稿中創(chuàng)建超鏈接。

創(chuàng)建超鏈接

您可以使用 XSLFTextRun 類的 createHyperlink()方法讀取演示文稿中的超鏈接。 按照下面給出的過程在演示中創(chuàng)建超鏈接。

使用 XMLSlideShow 類創(chuàng)建一個空的演示文稿，如下所示:

XMLSlideShow ppt = new XMLSlideShow();

創(chuàng)建一個空白幻燈片，并使用正文和內(nèi)容布局創(chuàng)建幻燈片的文本框和正文。

//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();

創(chuàng)建一個文本運行對象并設(shè)置文本到它，如下所示:

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

使用 XSLFTextRun 類的 createHyperlink()方法創(chuàng)建超鏈接，如下所示:

XSLFHyperlink link = textRun.createHyperlink();

使用 XSLFHyperlink 類的 setAddress()方法將鏈接地址設(shè)置為超鏈接，如下所示:

link.setAddress("//www.o2fo.com/");

下面給出了在演示文稿中創(chuàng)建超鏈接的完整程序:

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("Tutorials point");	
      
      //creating the hyperlink
      XSLFHyperlink link = textRun.createHyperlink();
      
      //setting the link address
      link.setAddress("//www.o2fo.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();              
   }
}

將上述Java代碼保存為 CreatingHyperlinks.java ，然后從命令提示符處編譯并執(zhí)行，如下所示:

$javac CreatingHyperlinks.java
$java CreatingHyperlinks

它將編譯并執(zhí)行以生成以下輸出:

slide cretated successfully 

新添加的幻燈片及其正文中的超鏈接如下所示:
