Java实现doc或xls转PDF

1.添加jar包：aspose-words-15.8.0-jdk16.jar

2.实现工具类：

package com.example.demo.config; import java.io.*; import com.aspose.words.*; //引入aspose-words-15.8.0-jdk16.jar包 public class Doc2Pdf { public static boolean getLicense() { boolean result = false; try { InputStream is = com.aspose.words.Document.class .getResourceAsStream("/license.xml"); License aposeLic = new License(); aposeLic.setLicense(is); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } public static void doc2pdf(String Address) { if (!getLicense()) { // 验证License 若不验证则转化出的pdf文档会有水印产生 return; } try { long old = System.currentTimeMillis(); File file = new File("D:/aaa/pdf1.pdf"); //新建一个空白pdf文档 FileOutputStream os = new FileOutputStream(file); Document doc = new Document(Address); //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(); } }     /**      * @param excelPath 需要被转换的excel全路径带文件名      * @param pdfPath   转换之后pdf的全路径带文件名      */     public static void excel2pdf(String excelPath, String pdfPath) {         if (!getLicense()) { // 验证License 若不验证则转化出的pdf文档会有水印产生             return;         }         try {             long old = System.currentTimeMillis();             Workbook wb = new Workbook(excelPath);// 原始excel路径             FileOutputStream fileOS = new FileOutputStream(new File(pdfPath));             wb.save(fileOS, com.aspose.cells.SaveFormat.PDF);             fileOS.close();             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 main(String[] args) { Doc2Pdf.doc2pdf("D:/交通部接口.docx"); } }
