實(shí)現(xiàn)doc，ppt，txt等格式文件向可以在flexPaper中預(yù)覽的翻頁動(dòng)畫swf的格式轉(zhuǎn)換，一般需要先把doc，ppt，txt等格式的文件先轉(zhuǎn)換為pdf，然后再由pdf轉(zhuǎn)換為swf才能實(shí)現(xiàn)在flexpaper中進(jìn)行預(yù)覽，實(shí)現(xiàn)類似百度豆丁的預(yù)覽效果，其轉(zhuǎn)換過程需要電腦安裝 openoffice，swfTools軟件，通過java代碼：實(shí)現(xiàn)文檔格式的轉(zhuǎn)換，下面我將我在一個(gè)分布式項(xiàng)目中的一個(gè)文檔預(yù)覽部分的思路與大家共享：
1.安裝openoffice，swfTools軟件，配置好java代碼的運(yùn)行環(huán)境。
2.啟動(dòng)openOffice服務(wù)：
①、進(jìn)入openoffice安裝目錄
cd opeonofiice的安裝路徑/program
②、啟動(dòng)端口監(jiān)聽
soffice -headless -accept="socket,host=127.0.0.1,port=8080;urp;" -nofirststartwizard
③、查看啟動(dòng)是否成功，存在8080端口即啟動(dòng)成功 netstat -an
3.在eclipse端運(yùn)行以下java代碼，實(shí)現(xiàn)文檔的格式轉(zhuǎn)換，并保存到

代碼已經(jīng)在MyEclipse上運(yùn)行測試無誤，可以實(shí)現(xiàn)將本地文件實(shí)現(xiàn)格式轉(zhuǎn)換，
4.注意：注意代碼中加載各個(gè)軟件的本地路徑要正確，防止加載不到軟件而報(bào)錯(cuò)
在代碼運(yùn)行前要啟動(dòng)openoffice服務(wù)，否則不能完成文件格式的轉(zhuǎn)換
