java实现类似百度文库功能linu

1、实现类似百度文库在线观看功能目录实现原理过程2资料和工具准备2工具准备和安装2项目目录及源码6程序运行需要openoffice服务支持1810/19实现原理过程 网上大致看了下实现的方式,大体上有四种转换的方式：1. Txt/Word/Excel/PPT=PDF(OpenOff ice+JodConverter)=SWF(pdf2swf)=FlexPap er浏览2. Txt/Word/Excel/PPT二PDF (MSOf f ice+JACOB)二SWF (pdf2swf)二FlexPaper 浏览-Txt/Word/ExceLPPT=SWF (FlashPaper)二FlexPaper

2、浏览4T-Txt/Word/Excel/PPT二SWF (print2flash)二)FlexPaper 浏览资料和工具准备工具OpenOfficeJodConverterSwftools(pdf 2swf)FlexPaper资料方面，大致搜索了百度文库和开源中国上的一些资料，其实都大同小异。工具准备和安装1 .安装openoffice3,这个安装过程很纠结，遇到过各种问题，因为先后在几台服务器上安装过，最顺利的安装方法如下tar zxvf 00o_3 3. 0_Linux_x86-64_install-rpm-wJRE_zh-CN. tar. gzcd RPEMrpm -ivh *. rpm

3、 -nodeps - force安装后的默认目录是在：/opt/目录下面启动服务：/opt/openoff ice. org3/program/soffice -headless一accept二socket， host=127 0 0 1, port=8100;urp;/z -nof irststartwizard &2 .来安装 openoffice sdktar zxvf 00o-SDK_3. 3. 0_Linux_x86-64_install-rpm_en-US. tar. gzcd 000330_m20_native_packed-l_en-US. 9567/RPMS/rpm -vih

4、 *. rpm3 . JODConverter其实不用安装 解压了就行安装jodconverter. 2. 2. 2 ,安装了这个之后就已经可以实现DOC转PDF 了。解压，复制到一个目录里面去，就能直接用了，调用它里面的/lib/jodconverter-cli-2. 2. 2. jar这个玩意儿就行，可以直接运行命令测试：java -jar /home/down1oad/jodeonverter-2. 2. 2/1ib/jodconverter-cli-2. 2. 2. jar/home/download/aaa. doc /home/download/1. pdf顺利的话就直接可以转成功

5、了exec (java -jar/home, down 1 oad,/jodconverter-2. 2. 2/lib/jodconverter-cli-2. 2. 2. jar/home, download/aaa. doc /home/down1oad/1. pdf)4 .
