Java實現(xiàn)Word/Excel/TXT轉(zhuǎn)PDF的方法

更新時間：2020年01月15日 10:18:16 作者：zsq_fengchen

這篇文章主要介紹了Java實現(xiàn)Word/Excel/TXT轉(zhuǎn)PDF的方法，本文給大家介紹的非常詳細(xì)，具有一定的參考借鑒價值,需要的朋友可以參考下

引言:

前段時間公司做的教育系統(tǒng),系統(tǒng)需要實時記錄用戶學(xué)習(xí)課程的情況和時間,所以對一些除視頻課程之外,對一些文本文檔型課件同樣如此,初次的方案是講office相關(guān)類型的文件進行轉(zhuǎn)換Html文件,然后展示對應(yīng)的html文件,PC端差不多沒問題了,但是個別文件再轉(zhuǎn)換html之后,樣式出現(xiàn)了錯亂,即時做了編碼轉(zhuǎn)換處理,但是還是有個別亂碼,最后改變方案,最后統(tǒng)一將文件轉(zhuǎn)為pdf,然后通過流的方式在前端展示,其中包括Word Excel PPT TXT PDF等文件,代碼如下:

備注:本來是可以直接展示pdf的,但是Andior上pdf展示不了,最后統(tǒng)一就用IO流的方式進行讀取展示了.

1：添加maven依賴

<!--excel word txt ppt轉(zhuǎn)pdf依賴-->
    <dependency>
      <groupId>aspose</groupId>
      <artifactId>pdf</artifactId>
      <version>11.5.0</version>
    </dependency>
    <dependency>
      <groupId>aspose</groupId>
      <artifactId>words</artifactId>
      <version>16.4.0</version>
    </dependency>
    <dependency>
      <groupId>aspose</groupId>
      <artifactId>cell</artifactId>
      <version>8.9.2</version>
    </dependency>
    <dependency>
      <groupId>aspose</groupId>
      <artifactId>pdf</artifactId>
      <version>11.5.0</version>
    </dependency>

2:添加license-excel.xml文件(Resource文件夾下)

<License>
 <Data>
  <Products>
   <Product>Aspose.Total for Java</Product>
   <Product>Aspose.Words for Java</Product>
  </Products>
  <EditionType>Enterprise</EditionType>
  <SubscriptionExpiry>20991231</SubscriptionExpiry>
  <LicenseExpiry>20991231</LicenseExpiry>
  <SerialNumber>8bfe198c-7f0c-4ef8-8ff0-acc3237bf0d7</SerialNumber>
 </Data>
 <Signature>sNLLKGMUdF0r8O1kKilWAGdgfs2BvJb/2Xp8p5iuDVfZXmhppo+d0Ran1P9TKdjV4ABwAgKXxJ3jcQTqE/2IRfqwnPf8itN8aFZlV3TJPYeD3yWE7IT55Gz6EijUpC7aKeoohTb4w2fpox58wWoF3SNp6sK6jDfiAUGEHYJ9pjU=</Signature>
</License>

3:代碼如下:

3.1獲取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:文本文件轉(zhuǎn)碼

/* 將txt 轉(zhuǎn)換編碼
  * @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("轉(zhuǎn)碼結(jié)束");
    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
    return file;
  }

3.3:word和txt轉(zhuǎn)換pdf

/**
 * 將word txt轉(zhuǎn)換成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();
      // 新建一個空白文檔
      file = new File(outPath);
      file = saveAsUTF8(file);
      os = new FileOutputStream(file);
      // InPath是將要被轉(zhuǎn)化的文檔
      com.aspose.words.Document doc = new com.aspose.words.Document(inPath);
      /*
       * 全面支持DOC,DOCX進行OOXML,RTF,HTML,OpenDocument,PDF,EPUB,XPS,SWF間轉(zhuǎn)換
       */
      doc.save(os, SaveFormat.PDF);
      flag = true;
      //long now = System.currentTimeMillis();
      //System.out.println("共耗時：" + ((now - old) / 1000.0) + "秒"); // 轉(zhuǎn)化用時
      
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }
    finally
    {
      try
      {
        if (os != null)
        {
          os.close();
        }
      }
      catch (Exception e)
      {
        e.printStackTrace();
      }
      if (!flag)
      {
        file.deleteOnExit();
      }
    }
  }

3.4:Excel轉(zhuǎn)換pdf

/**
 * 將docx轉(zhuǎn)換成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();
      // 新建一個空白文檔
      file = new File(outPath);
      file = saveAsUTF8(file);
      os = new FileOutputStream(file);
      // InPath是將要被轉(zhuǎn)化的文檔
      com.aspose.words.Document doc = new com.aspose.words.Document(inPath);
      /*
       * 全面支持DOC,DOCX進行OOXML,RTF,HTML,OpenDocument,PDF,EPUB,XPS,SWF間轉(zhuǎn)換
       */
      doc.save(os, SaveFormat.PDF);
      flag = true;
      //long now = System.currentTimeMillis();
      //System.out.println("共耗時：" + ((now - old) / 1000.0) + "秒"); // 轉(zhuǎn)化用時
      
    }
    catch (Exception e)
    {
      e.printStackTrace();
    }
    finally
    {
      try
      {
        if (os != null)
        {
          os.close();
        }
      }
      catch (Exception e)
      {
        e.printStackTrace();
      }
      if (!flag)
      {
        file.deleteOnExit();
      }
    }
  }
