This article will explain in detail how to use Java to achieve Word/Excel/TXT to PDF function, the editor thinks it is very practical, so share it for you to do a reference, I hope you can get something after reading this article.

1: add maven dependency

Aspose pdf 11.5.0 aspose words 16.4.0 aspose cell 8.9.2 aspose pdf 11.5.0

2: add license-excel.xml files (under the Resource folder)

Aspose.Total for Java Aspose.Words for Java Enterprise 20991231 20991231 8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7 sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=

3: the code is as follows:

3.1 get License file

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: text file transcoding

/ * Transcoding txt * @ 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 ("transcoding end");} catch (FileNotFoundException e) {e.printStackTrace ();} catch (IOException e) {e.printStackTrace ();} return file;}

3.3:word and txt convert pdf

/ * * convert word txt to 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 (); / / create a new blank document file = new File (outPath); file = saveAsUTF8 (file) Os = new FileOutputStream (file); / / InPath is the document to be converted com.aspose.words.Document doc = new com.aspose.words.Document (inPath); / * * DOC,DOCX is fully supported for inter-OOXML,RTF,HTML,OpenDocument,PDF,EPUB,XPS,SWF conversion * / doc.save (os, SaveFormat.PDF); flag = true; / / long now = System.currentTimeMillis () / / System.out.println ("Total time:" + ((now-old) / 1000.0) + "seconds"); / / conversion time} catch (Exception e) {e.printStackTrace ();} finally {try {if (os! = null) {os.close () }} catch (Exception e) {e.printStackTrace ();} if (! flag) {file.deleteOnExit ();}

3.4:Excel conversion pdf

/ * * convert docx to 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 (); / / create a blank document file = new File (outPath); file = saveAsUTF8 (file) Os = new FileOutputStream (file); / / InPath is the document to be converted com.aspose.words.Document doc = new com.aspose.words.Document (inPath); / * * DOC,DOCX is fully supported for inter-OOXML,RTF,HTML,OpenDocument,PDF,EPUB,XPS,SWF conversion * / doc.save (os, SaveFormat.PDF); flag = true; / / long now = System.currentTimeMillis () / / System.out.println ("Total time:" + ((now-old) / 1000.0) + "seconds"); / / conversion time} catch (Exception e) {e.printStackTrace ();} finally {try {if (os! = null) {os.close () }} catch (Exception e) {e.printStackTrace ();} if (! flag) {file.deleteOnExit () } on "how to use Java to achieve Word/Excel/TXT to PDF function" this article is shared here, I hope the above content can be of some help to you, so that you can learn more knowledge, if you think the article is good, please share it out for more people to see.
