            system
            ${basedir}/src/main/resources/lib/aspose-slides-22.12.jar
        

2.license.xml文件

3.centos7系统下，需要拷贝字体文件到指定目录

将windows系统下的字体目录下所有的字体文件 C:\Windows\Fonts\

/app/fontFiles/fonts/

package com.xkj.utils;
import com.aspose.slides.FontsLoader;
import com.aspose.slides.Presentation;
import com.aspose.words.Document;
import com.aspose.words.FontSettings;
import com.aspose.words.License;
import com.aspose.words.SaveFormat;
import org.springframework.core.io.ClassPathResource;

import java.io.*;

public class DocToDocxConverter {

        public static void main(String[] args) {
            doc2pdf("D:\aa.doc",
                    "D:\output.pdf");
            ppt2pdf("D:\bb.ppt",
                    "D:\xxx.pdf");
        }

        public static boolean getLicense() {
            boolean result = false;
            try {
                ClassPathResource classPathResource = new ClassPathResource("license.xml");
                InputStream inputStream = classPathResource.getInputStream();
                License aposeLic = new License();
                aposeLic.setLicense(inputStream);
                result = true;
            } catch (Exception e) {
                e.printStackTrace();
            }
            return result;
        }

        public static void doc2pdf(String inPath, String outPath) {
            if (!getLicense()) { // 验证License 若不验证则转化出的pdf文档会有水印产生
                return;
            }
            // aspose不支持linux 增加字体即可
            FontSettings.setFontsFolders(new String[]{"/app/fontFiles/fonts/"},
                    true);
            try {
                long old = System.currentTimeMillis();
                File file = new File(outPath); // 新建一个空白pdf文档
                FileOutputStream os = new FileOutputStream(file);
                Document doc = new Document(inPath); // Address是将要被转化的word文档
                doc.save(os, SaveFormat.PDF);// 全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF,
                // EPUB, XPS, SWF 相互转换
                long now = System.currentTimeMillis();
                System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒"); // 转化用时
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        public static void ppt2pdf(String inPath, String outPath) {
            try {
                Presentation ppt = new Presentation(inPath);
                FontsLoader.loadExternalFonts(new String[]{"/app/fontFiles/fonts/"});
                FileOutputStream fileOS = new FileOutputStream(new File(outPath));
                ppt.save(fileOS, com.aspose.slides.SaveFormat.Pdf);
                fileOS.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
