一、使用Jodconverter 利用OpenOffice3.X将Office文件转换成HTML,PDF

 

 JAVA中使用jodconverter 利用OpenOffice3.X将office文件转换成HTML或是PDF

项目中，经常有用户将一些Office文档上传到应用中。之后如果需要查看的话，只能下载，才能查看。

为了达到更好的用户体验，需要不用下载Office文件就能在网页中查看文件内容。于是只好将Office文件转换成HTML或是PDF直接显示在网页中。就实现了在网页中直接查看的效果。

这种方法需要在服务端安装OpenOffice3.X的。但是比起需要在客户端安装office还是在服务器端安装更好一点。下面就是根据网上查找的一些资料，初步实现了转换工能。

第一步：下载 jodconverter-core-3.0-beta-4.zip

解开后导入下列jar

        jodconverter-core-3.0-beta-4.jar

        commons-cli-1.1.jar

        commons-io-1.4.jar

        json-20090211.jar

        juh-3.2.1.jar

        jurt-3.2.1.jar

        ridl-3.2.1.jar

        unoil-3.2.1.jar

导入相关的包：

第二步：下载OpenOffice3.X,安装

二、Jacob来调用excel另存功能

 

  需要下载jacob的包，该包还包含2个dll文件，一个是jacob-1.17-x64.dll，这个是64位的，还有一个是jacob-1.17-x86.dll文件，这个是32位的。将jar包包含到classpath目录，dll文件包含到jre/bin目录即可

 以上是jacob利用另存把excel转成pdf文件，但是我没有找到多个sheet转化为一个pdf的方法，我使用遍历sheet保存多个pdf文件，通过itextpdf再将这多个PDF合成一个，效率偏低不过能够实现

					savepath = staticpath + savepath + "0" + i + ".pdf";
					savepaths.add(savepath);
