合并 ppt

合并ppt (要解决格式需要购买专业的jar包,下面一种免费的格式处理不了,一种收费的可以处理格式问题)
代码(不处理格式)

				XMLSlideShow src = new XMLSlideShow(inputstream);
				for (XSLFSlide srcSlide : src.getSlides()) {
     
					// merging the contents
					ppt.createSlide().importContent(srcSlide);
				}
			}

			// 删除第一个文件
			new File(filePath1).delete();
			// 删除第二个文件

			// creating the file object

			ppt.write(out);
			out.close();
		} catch (IOException e) {

代码(处理格式)

package com.ebon.hello.controller;

import com.spire.presentation.*;

public class HeBingPPt {
     
    public static void main(String[] args) throws Exception{
     
        //加载文档1，文档2
        Presentation ppt1 = new Presentation();
        ppt1.loadFromFile("D://template//b.pptx");
        Presentation ppt2 = new Presentation();
        ppt2.loadFromFile("D://template//a.pptx");

        //遍历文档1的所有幻灯片，添加到文档2
        for(int i = 0;i<ppt1.getSlides().getCount();i++){
     
            ppt2.getSlides().append(ppt1.getSlides().get(i));
        }

        //保存文档2
        ppt2.saveToFile("D://template//c.pptx",FileFormat.PPTX_2013);
        ppt2.dispose();
    }
