使用POI转换word doc文件

目录

1       转换为Html文件

2       转换为Xml文件

3       转换为Text文件

       在POI中还存在有针对于word doc文件进行格式转换的功能。我们可以将word的内容转换为对应的Html文件，也可以把它转换为底层用来描述doc文档的xml文件，还可以把它转换为底层用来描述doc文档的xml格式的text文件。这些格式转换都是通过AbstractWordConverter特定的子类来完成的。

1       转换为Html文件

       将doc文档转换为对应的Html文档是通过WordToHtmlConverter类进行的。它会尽量的利用Html的方式来呈现原文档的样式。示例代码：

/**
 * Word转换为Html
 * @throws Exception
 */
@Test
public void testWordToHtml() throws Exception {
   InputStream is = new FileInputStream("D:\test.doc");
   HWPFDocument wordDocument = new HWPFDocument(is);
   WordToHtmlConverter converter = new WordToHtmlConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
   //对HWPFDocument进行转换
   converter.processDocument(wordDocument);
     Writer writer = new FileWriter(new File("D:\converter.html"));
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.setOutputProperty( OutputKeys.ENCODING, "utf-8" );
    //是否添加空格
     transformer.setOutputProperty( OutputKeys.INDENT, "yes" );
    transformer.setOutputProperty( OutputKeys.METHOD, "html" );
    transformer.transform(
                new DOMSource(converter.getDocument() ),
                new StreamResult( writer ) );
}

2       转换为Xml文件

       将doc文档转换为对应的Xml文件是通过WordToFoConverter类进行的。它可以把doc文档转换为底层用来描述doc文档的Xml文档。示例代码：

   /**
    * Word转Fo
    * @throws Exception
    */
   @Test
   public void testWordToFo() throws Exception {
      InputStream is = new FileInputStream("D:\test.doc");
      HWPFDocument wordDocument = new HWPFDocument(is);
      WordToFoConverter converter = new WordToFoConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
      //对HWPFDocument进行转换
      converter.processDocument(wordDocument);
        Writer writer = new FileWriter(new File("D:\converter.xml"));
       Transformer transformer = TransformerFactory.newInstance().newTransformer();
       transformer.setOutputProperty( OutputKeys.ENCODING, "utf-8" );
       //是否添加空格
        transformer.setOutputProperty( OutputKeys.INDENT, "yes" );
//     transformer.setOutputProperty( OutputKeys.METHOD, "html" );
       transformer.transform(
                   new DOMSource(converter.getDocument() ),
                   new StreamResult( writer ) );
   }

3       转换为Text文件

       将doc文档转换为text文档是通过WordToTextConverter来进行的。它可以把doc文档转换为底层用于描述doc文档的Xml格式的text文档。示例代码：

/**
 * Word转换为Text
 * @throws Exception
 */
@Test
public void testWordToText() throws Exception {
   InputStream is = new FileInputStream("D:\test.doc");
   HWPFDocument wordDocument = new HWPFDocument(is);
   WordToTextConverter converter = new WordToTextConverter(DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument());
   //对HWPFDocument进行转换
   converter.processDocument(wordDocument);
     Writer writer = new FileWriter(new File("D:\converter.txt"));
    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.setOutputProperty( OutputKeys.ENCODING, "utf-8" );
    //是否添加空格
     transformer.setOutputProperty( OutputKeys.INDENT, "yes" );
    transformer.setOutputProperty( OutputKeys.METHOD, "text" );
    transformer.transform(
                new DOMSource(converter.getDocument() ),
                new StreamResult( writer ) );
}
