java word文档 转 html文件

一、简介
　　一般word文件后缀有doc、docx两种。docx是office word 2007以及以后版本文档的扩展名；doc是office word 2003文档保存的扩展名。对于这两种格式的word转换成html需要使用不同的方法。
对于docx格式的文档使用xdocreport进行转换。依赖如下：

<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>fr.opensagres.xdocreport.document</artifactId>
    <version>1.0.5</version>
</dependency>
<dependency>
    <groupId>fr.opensagres.xdocreport</groupId>
    <artifactId>org.apache.poi.xwpf.converter.xhtml</artifactId>
    <version>1.0.5</version>
</dependency>

对于docx格式的文档使用poi进行转换。依赖如下：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>3.12</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-scratchpad</artifactId>
    <version>3.12</version>
</dependency>

         File f = new File(file);
         if (!f.exists()) {
             System.out.println("Sorry File does not Exists!");
         } else {
             if (f.getName().endsWith(".docx") || f.getName().endsWith(".DOCX")) {  

                 // 1) 加载word文档生成 XWPFDocument对象
                 InputStream in = new FileInputStream(f);
                 XWPFDocument document = new XWPFDocument(in);

                 options.setIgnoreStylesIfUnused(false);
                 options.setFragment(true);  

                 // 3) 将 XWPFDocument转换成XHTML
                 OutputStream out = new FileOutputStream(new File(filepath + htmlName));
                 XHTMLConverter.getInstance().convert(document, out, options);  

                 //也可以使用字符数组流获取解析的内容

             } else {
                 System.out.println("Enter only MS Office 2007+ files");
             }
         }
     }

                 }
                 return imagepath + suggestedName;
             }
         });

         //解析word文档
         wordToHtmlConverter.processDocument(wordDocument);
         Document htmlDocument = wordToHtmlConverter.getDocument();

         File htmlFile = new File(filepath + htmlName);
         OutputStream outStream = new FileOutputStream(htmlFile);

         //也可以使用字符数组流获取解析的内容
 //        ByteArrayOutputStream baos = new ByteArrayOutputStream();
 //        OutputStream outStream = new BufferedOutputStream(baos);

         DOMSource domSource = new DOMSource(htmlDocument);
         StreamResult streamResult = new StreamResult(outStream);

         TransformerFactory factory = TransformerFactory.newInstance();
         Transformer serializer = factory.newTransformer();
         serializer.setOutputProperty(OutputKeys.ENCODING, "utf-8");
         serializer.setOutputProperty(OutputKeys.INDENT, "yes");
         serializer.setOutputProperty(OutputKeys.METHOD, "html");

         serializer.transform(domSource, streamResult);

         //也可以使用字符数组流获取解析的内容
 //        String content = baos.toString();
 //        System.out.println(content);
 //        baos.close();
         outStream.close();
     }
 }

　　运行生存文件结果如下：
