WORD03,WOR07 和PPT转HTML

项目中需要用OFFICE系列转成HTML展示出来，所以写了个工具类，转03,07与PPT的，由于EXCEL基本不需要，所以没有。由于POI是将整个个文件读入到内存中，所以无法转换过大的OFFICE文档。

需要引入的JAR包（MAVEN）：

<dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi</artifactId>            <version>3.9</version>        </dependency>        <dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi-ooxml</artifactId>            <version>3.9</version>        </dependency>        <dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi-scratchpad</artifactId>            <version>3.9</version>        </dependency>          <dependency>            <groupId>fr.opensagres.xdocreport</groupId>            <artifactId>org.apache.poi.xwpf.converter.xhtml</artifactId>            <version>1.0.4</version>        </dependency>
