在Java编程中,如何合并两个PPT文档?
注意:需要访问网址:http://poi.apache.org/download.html , 下载一个Apache POI软件包。这里下载最新版本:poi-bin-3.17-20170915.tar.gz解压并全部导入 。
需要导入全部包,如下图所示 -

以下是使用Java合并两个PPT文档的程序。
package com.zaixian;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.xslf.usermodel.XMLSlideShow;
import org.apache.poi.xslf.usermodel.XSLFSlide;
public class MergingMultiplePresentations {
    public static void main(String args[]) throws IOException {
        // creating empty presentation
        XMLSlideShow ppt = new XMLSlideShow();
        // taking the two presentations that are to be merged
        String file1 = "aboutus1.pptx";
        String file2 = "aboutus2.pptx";
        String[] inputs = { file1, file2 };
        for (String arg : inputs) {
            FileInputStream inputstream = new FileInputStream(arg);
            XMLSlideShow src = new XMLSlideShow(inputstream);
            for (XSLFSlide srcSlide : src.getSlides()) {
                // merging the contents
                ppt.createSlide().importContent(srcSlide);
            }
        }
        String file3 = "aboutus12.pptx";
        // creating the file object
        FileOutputStream out = new FileOutputStream(file3);
        // saving the changes to a file
        ppt.write(out);
        System.out.println("Merging done successfully");
        out.close();
    }
}
执行上面示例代码,得到以下结果 -
Merging done successfully
这就创建一个PPT文件:aboutus12.pptx了,如下所示 -
