1、配置license

在resources目录下创建license.xml文件，代码如下：

<License>  <Data>    <Products>      <Product>Aspose.Total for Java</Product>      <Product>Aspose.Words for Java</Product>    </Products>    <EditionType>Enterprise</EditionType>    <SubscriptionExpiry>20991231</SubscriptionExpiry>    <LicenseExpiry>20991231</LicenseExpiry>    <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>  </Data>  <Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature></License>

引入jar包：
aspose没有相应的maven地址，所有手动引入jar包；

aspose-cells-20.4 - c.jar
aspose-words-18.10-jdk16.jar

2、excel转pdf

封装工具类：

import com.aspose.cells.*;import com.aspose.cells.License;import com.aspose.cells.LoadOptions;import com.aspose.cells.PdfSaveOptions;import java.io.*;/** * @Author: LiHuaZhi * @Date: 2021/7/13 14:21 * @Description: **/public class Excel2PdfUtil {    /**     * 加载配置文件     * @return     */    private static boolean getLicense() { boolean result = false; try (InputStream in = Doc2PdfUtil.class.getClassLoader().getResourceAsStream("license.xml")) {     License license = new License();     license.setLicense(in);     result = true; } catch (Exception e) {     e.printStackTrace(); } return result;    }    /**     * @param inputStream     * @param docPath     * @param pdfPath     * @description 如果流不为空则使用转pdf，反之则用docPath进行转pdf     */    public static File excel2Pdf(InputStream inputStream, String docPath, String pdfPath) { System.out.println("pdf转换中..."); long old = System.currentTimeMillis(); File pdfFile = new File(pdfPath); try (FileOutputStream fos = new FileOutputStream(pdfFile)) {     // 验证     if (!getLicense()) {  throw new RuntimeException("文件转换失败!");     }     // 设置字体包位置 - 不同环境可用从配置文件中获取     IndividualFontConfigs configs = new IndividualFontConfigs();     // configs.setFontFolder("/usr/share/fonts/chinese", true);     configs.setFontFolder("C:\\Windows\\Fonts", true);     LoadOptions loadOptions = new LoadOptions();     loadOptions.setFontConfigs(configs);     Workbook workbook;     if (inputStream != null) {  workbook = new Workbook(inputStream, loadOptions);     } else {  workbook = new Workbook(docPath, loadOptions);     }     PdfSaveOptions opts = new PdfSaveOptions();     // 设置excel不换行在pdf显示     // opts.setAllColumnsInOnePagePerSheet(true);     // 设置一个sheet在一页pdf     opts.setOnePagePerSheet(true);     workbook.save(fos, opts);     long now = System.currentTimeMillis();     System.out.println("pdf转换成功，共耗时：" + ((now - old) / 1000.0) + "秒");     return pdfFile; } catch (Exception e) {     e.printStackTrace();     throw new RuntimeException("文件转换失败!"); } finally {     try {  if (inputStream != null) {      inputStream.close();  }     } catch (IOException e) {  e.printStackTrace();     } }    }}

Controller实现：

    @RequestMapping("/excel")    @ResponseBody    public void uploadExcel(@RequestParam("file") MultipartFile file) throws Exception { String docPath = "C:\\Users\\LiGezZ\\Desktop\\ad.xlsx"; String pdfPath = "C:\\Users\\LiGezZ\\Desktop\\test.pdf"; File pdf = Excel2PdfUtil.excel2Pdf(file.getInputStream(), docPath, pdfPath);    }

3、word转pdf

封装工具类：

import java.io.*;import com.aspose.words.*;/** * @Author: LiHuaZhi * @Date: 2021/7/13 14:21 * @Description: **/public class Doc2PdfUtil {    /**     * 加载配置文件     *     * @return     */    private static boolean getLicense() { boolean result = false; try (InputStream in = Doc2PdfUtil.class.getClassLoader().getResourceAsStream("license.xml")) {     License license = new License();     license.setLicense(in);     result = true; } catch (Exception e) {     e.printStackTrace(); } return result;    }    /**     * doc转pdf     *     * @param docPath doc文件路径，包含.doc     * @param pdfPath pdf文件路径，包含.pdf     * @description 如果流不为空则使用转pdf，反正则用docPath进行转pdf     */    public static File doc2Pdf(InputStream inputStream, String docPath, String pdfPath) { System.out.println("pdf转换中..."); long old = System.currentTimeMillis(); File pdfFile = new File(pdfPath); try (FileOutputStream fos = new FileOutputStream(pdfFile)) {     // 验证     if (!getLicense()) {  throw new RuntimeException("文件转换失败!");     }     // FontSettings.getDefaultInstance().setFontsFolder("/usr/share/fonts/chinese", true);     FontSettings.getDefaultInstance().setFontsFolder("C:\\Windows\\Fonts", true);     Document document;     if (inputStream != null) {  document = new Document(inputStream);     } else {  document = new Document(docPath);     }     //  DocumentBuilder builder = new DocumentBuilder(document);     // 设置纸张大小     //  builder.getPageSetup().setPaperSize(PaperSize.A3);     // 设置横向     // builder.getPageSetup().setOrientation(Orientation.LANDSCAPE);     document.save(fos, SaveFormat.PDF);     long now = System.currentTimeMillis();     System.out.println("pdf转换成功，共耗时：" + ((now - old) / 1000.0) + "秒");     return pdfFile; } catch (Exception e) {     e.printStackTrace();     throw new RuntimeException("文件转换失败!"); } finally {     try {  if (inputStream != null) {      inputStream.close();  }     } catch (IOException e) {  e.printStackTrace();     } }    }}

Controller实现：

    @RequestMapping("/word")    @ResponseBody    public void uploadWord(@RequestParam("file") MultipartFile file) throws Exception { String docPath = "C:\\Users\\LiGezZ\\Desktop\\test.docx"; String pdfPath = "C:\\Users\\LiGezZ\\Desktop\\test.pdf"; File pdf = Doc2PdfUtil.doc2Pdf(file.getInputStream(), docPath, pdfPath);    }
