1.用OpenOffice把PPT、Word、Excel、Text转换为pdf
2.用SWFTool将生成的pdf转换成swf,然后利用FlexPlayer实现在线预览播放
二、准备工作
1.安装OpenOffice,官网下载地址:http://www.openoffice.org/download/index.html,最新版为3.4.1,我使用的版本为3.3.0:http://pan.baidu.com/share/link?shareid=1181746637&uk=1913152192#dir/path=%2F%E8%BD%AF%E4%BB%B6%E5%B7%A5%E5%85%B7
2.启动OpenOffice服务,CMD命令进入OpenOffice安装目录下的program目录,键入如下命令
soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" -nologo -headless -nofirststartwizard

3.下载JODConverter:http://sourceforge.net/projects/jodconverter/files/,项目中主要使用lib目录下的jar包。
4.下载并安装SWFTools:http://www.swftools.org/download.html,下载exe文件安装完成即可
5.下载FlexPlayer
http://pan.baidu.com/share/link?shareid=1181746637&uk=1913152192#dir/path=%2F%E8%BD%AF%E4%BB%B6%E5%B7%A5%E5%85%B7
官网下载地址:http://flexpaper.devaldi.com/download/,版本为2.1.5,与1.5.1有较大差别,未使用最新版。
新建OfficeOnline项目,引入相应jar包(使用的是cos进行文档上传,cos.jar需要另外下载),将FlexPaper_1.5.1_flash.zip解压后的js目录引入到项目中,FlexPaperViewer.swf也引入进来
2.新建DocConverter.java
注意:根据SWFTools安装路径不同需要修改pdf2swf()方法中pdf2swf.exe的路径,我安装的路径是在D盘
main()测试中根据自己文档路径进行修改测试。
