1:添加maven依赖
aspose 11.5.0 aspose words 16.4.0 aspose cell 8.9.2 aspose 11.5.0
2:添加license-excel.xml文件(Resource文件夹下)
Aspose.Total for Java Aspose.Words for Java Enterprise 20991231 20991231 8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7 sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=
3:代码如下:
3.1获取License文件
public static boolean getLicense(){ boolean result = false; InputStream is = null; try{ is =UploadFiles.class.getClassLoader().getResourceAsStream("license-excel.xml"); License aposeLic = new License(); aposeLic.setLicense(is); result = true; }catch(Exception e){ e.printStackTrace(); }finally{ try { is.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } return result; }
3.2:文本文件转码
/* 将txt 转换编码 * @param file * @author zsqing */public File saveAsUTF8(File file){ String code = "gbk"; byte[] head = new byte[3]; try { InputStream inputStream = new FileInputStream(file); inputStream.read(head); if (head[0] == -1 && head[1] == -2) { code = "UTF-16"; } else if (head[0] == -2 && head[1] == -1) { code = "Unicode"; } else if (head[0] == -17 && head[1] == -69 && head[2] == -65) { code = "UTF-8"; } inputStream.close(); System.out.println(code); if (code.equals("UTF-8")) { return file; } String str = FileUtils.readFileToString(file, code); FileUtils.writeStringToFile(file, str, "UTF-8"); System.out.println("转码结束"); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return file; }
3.3:word和txt转换pdf
/** * 将word txt转换成pdf * @param inPath * @param outPath * @author zsqing*/public void wordAndTextToPdf(String inPath, String outPath ,String localIP,HttpServletRequest request) { String fileToPdfUrl=""; boolean flag = false; File file = null; FileOutputStream os = null; try { //long old = System.currentTimeMillis(); // 新建一个空白文档 file = new File(outPath); file = saveAsUTF8(file); os = new FileOutputStream(file); // InPath是将要被转化的文档 com.aspose.words.Document doc = new com.aspose.words.Document(inPath); /* * 全面支持DOC,DOCX进行OOXML,RTF,HTML,OpenDocument,PDF,EPUB,XPS,SWF间转换 */ doc.save(os, SaveFormat.PDF); flag = true; //long now = System.currentTimeMillis(); //System.out.println("共耗时:" + ((now - old) / 1000.0) + "秒"); // 转化用时 } catch (Exception e) { e.printStackTrace(); } finally { try { if (os != null) { os.close(); } } catch (Exception e) { e.printStackTrace(); } if (!flag) { file.deleteOnExit(); } } }
3.4:Excel转换pdf
/** * 将docx转换成pdf * @param inPath * @param outPath * @author zsqing */ public void wordToPdf(String inPath, String outPath ,String localIP,HttpServletRequest request) { String fileToPdfUrl=""; boolean flag = false; File file = null; FileOutputStream os = null; try { //long old = System.currentTimeMillis(); // 新建一个空白文档 file = new File(outPath); file = saveAsUTF8(file); os = new FileOutputStream(file); // InPath是将要被转化的文档 com.aspose.words.Document doc = new com.aspose.words.Document(inPath); /* * 全面支持DOC,DOCX进行OOXML,RTF,HTML,OpenDocument,PDF,EPUB,XPS,SWF间转换 */ doc.save(os, SaveFormat.PDF); flag = true; //long now = System.currentTimeMillis(); //System.out.println("共耗时:" + ((now - old) / 1000.0) + "秒"); // 转化用时 } catch (Exception e) { e.printStackTrace(); } finally { try { if (os != null) { os.close(); } } catch (Exception e) { e.printStackTrace(); } if (!flag) { file.deleteOnExit(); } } }
