## 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![在这里插入图片描述][060b95ccad28488687fe91611e0de10f.png]
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");
        }
