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：

145 } 146 }
运行生存文件结果如下：
