【转载】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>

二：示例
　　代码示例如下：

package com.test.word;

import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

                options.setFragment(true);  
                  
                // 3) 将 XWPFDocument转换成XHTML  
                OutputStream out = new FileOutputStream(new File(filepath + htmlName));
