2. maven添加依赖

1. 在项目根目录创建lib文件夹
2. 将下载的aspose-slides.jar包，放在lib目录下
3. 在pom.xml 引入本地依赖包

    <dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-slides</artifactId>
            <version>19.3</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/lib/aspose.slides-19.3.jar</systemPath>
        </dependency>

3. 将license.xml文件放置在resources根目录下（去水印）

4. 创建java类，编写代码

import com.aspose.slides.License;
import com.aspose.slides.Presentation;

import com.aspose.slides.SaveFormat;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.core.io.support.ResourcePatternResolver;

import java.io.*;
import java.util.Date;

public class PPT2PdfAsposeUtil {
    public static boolean getLicensePPT() {
        boolean result = false;
        InputStream is = null;
        try {
            ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
            org.springframework.core.io.Resource[] resources = resolver.getResources("classpath:license.xml");
            is = resources[0].getInputStream();
            License aposeLic = new License();
            aposeLic.setLicense(is);
            result = true;
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (is != null) {
                try {
                    is.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return result;
    }

    /**
     *
     * @param inPath ppt路径
     * @param outPath pdf路径
     * @return
     */
    public static boolean ppt2Pdf(String inPath,String outPath){
        // 验证License 去除水印
        if (!getLicensePPT()) {
            return false;
        }
        long start = new Date().getTime();
        try {
            FileInputStream fileInput = new FileInputStream(inPath);
            Presentation pres = new Presentation(fileInput);
            FileOutputStream out = new FileOutputStream(new File(outPath));
            pres.save(out, SaveFormat.Pdf);
            out.close();
        } catch (Exception e) {
             e.printStackTrace();
            return false;
        }
        long end = new Date().getTime();
        System.out.println("pdf转换成功，共耗时：" + ((end - start) / 1000.0) + "秒"); // 转化用时
        return true;
    }

    public static void main(String[] args) {
        ppt2Pdf("E:\\code\\test\\1.pptx","E:\\code\\test\\1.pdf");
    }
}

5. 测试

执行main方法

 public static void main(String[] args) {
        ppt2Pdf("E:\\code\\test\\1.pptx","E:\\code\\test\\1.pdf");
    }
