aspose-cells.jar实现Excel文件转换为PDF文件

利用 aspose-cells-8.5.2.jar 实现 excel 内容转换为 pdf 文件输出。
开发过程中如果不验证 License 输出文件中会产生水印，详见如下 verifyLicense() 方法
主要实现代码：

/*** @param src 需要被转换的excel全路径带文件名* @param dest 转换之后pdf的全路径带文件名* @throws GeneralException*/public static void convert(String src,String dest) throws GeneralException {
    // 验证License 若不验证则转化出的pdf文档会有水印产生if (!verifyLicense()) {
     throw new GeneralException("License验证失败！");}try (FileOutputStream fileOS = new FileOutputStream(new File(dest));) {
    Workbook wb = new Workbook(src);wb.save(fileOS, com.aspose.cells.SaveFormat.PDF);} catch (Exception e) {
    e.printStackTrace();}}private static boolean verifyLicense() {
    boolean result = false;try {
    InputStream is = Excel2pdfUtil.class.getResourceAsStream("/license.xml");License aposeLic = new License();aposeLic.setLicense(is);result = true;} catch (Exception e) {
    e.printStackTrace();}return result;}
