发表于：2025-01-31 作者：千家信息网编辑

千家信息网最后更新 2025年01月31日，这篇文章将为大家详细讲解有关如何使用Java实现Word/Excel/TXT转PDF功能，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。1：添加maven依赖 aspose pdf 11.5.0 aspose words 16.4.0 aspose cell 8.9.2 aspose pdf 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();      }    }  }
