1.用OpenOffice把PPT、Word、Excel、Text轉換爲pdf
2.用SWFTool將生成的pdf轉換成swf,而後利用FlexPlayer實如今線預覽播放
2、準備工做
1.安裝OpenOffice,官網下載地址:http://www.openoffice.org/download/index.html,最新版爲3.4.1,我使用的版本爲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.啓動OpenOffice服務,CMD命令進入OpenOffice安裝目錄下的program目錄,鍵入以下命令
soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" -nologo -headless -nofirststartwizard
參考資料:http://blog.csdn.net/hbcui1984/article/details/5109169
3.下載JODConverter:http://sourceforge.net/projects/jodconverter/files/,項目中主要使用lib目錄下的jar包。
4.下載並安裝SWFTools:http://www.swftools.org/download.html,下載exe文件安裝完成便可
5.下載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
官網下載地址:http://flexpaper.devaldi.com/download/,版本爲2.1.5,與1.5.1有較大差異,未使用最新版。 javascript
新建OfficeOnline項目,引入相應jar包(使用的是cos進行文檔上傳,cos.jar須要另外下載),將FlexPaper_1.5.1_flash.zip解壓後的js目錄引入到項目中,FlexPaperViewer.swf也引入進來
2.新建DocConverter.java
注意:根據SWFTools安裝路徑不一樣須要修改pdf2swf()方法中pdf2swf.exe的路徑,我安裝的路徑是在D盤
main()測試中根據本身文檔路徑進行修改測試。 css
