java实现类似百文库功能linux

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5程序运行需要openoffice服务支持12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(OpenOffice+JodConverter)=>SWF(pdf2swf)=>FlexPaper浏览2. Txt/Word/Excel/PPT=>PDF(MSOffice+JACOB)=>SWF(pdf2swf)=>FlexPaper浏览3. Txt/Word/Excel/PPT=>SWF (Flas

2、hPaper)=> FlexPaper浏览4. Txt/Word/Excel/PPT=>SWF(print2flash)=> FlexPaper浏览资料和工具准备工具OpenOfficeJodConverterSwftools(pdf2swf)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cd RPEMrpm -ivh *.rpm -nodeps force安装后的默认目录是在：/opt/目录下面启动服务

3、：/opt/3/program/soffice -headless -accept="socket,host=,port=8100;urp;" -nofirststartwizard &2.来安装openoffice sdkcd OOO330_m20_native_packed-1_en-US.9567/RPMS/rpm -vih *.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

4、，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：顺利的话就直接可以转成功了exec("java -jar /home/download/jodconverter-2.2.2/lib/jodconverter-cli-2.2.2.jar /home/download/aaa.doc /home/download/1.pdf")4.Linux下安装pdf2swf Tool中文支持安装：1）  mkdir p /usr/share/xpdfcd /usr/share/xpdf/2） &

5、#160;下载中文支持及字体库wget  ftp:/ftp.foolabs.          unzip font.zipmv Gbsn00lp.ttf gkai00mp.ttf xpdf-chinese-simplified/CMap/cd /usr/share/xpdf/xpdf-chinese-simplified4）vi add-to-xpdfrc内容如下：cidToUnicode   Adobe-GB1

9、df/xpdf-chinese-simplified/CMapdisplayCIDFontTT Adobe-GB1 /usr/share/xpdf/xpdf-chinese-simplified/CMap/gkai00mp.ttf保存后退出 相关Lib包安装:1）  yum y install gcc-c+(如果已安装可跳过)2）  yum install giflib-devel.x86_643）  yum install zlib-devel.x86_644）  yum install freetyp

10、e-devel.x86_645）  yum install libjpeg-devel.x86_64 SwfTool安装：1）cd /usr/local/5）./configure -prefix=/usr/local/swftools6）make7）make install8）测试一下是否可用./usr/local/swftools/bin/pdf2swf -o /path/output.swf -T -z -t -f /path/yourpdffile.pdf -s languagedir=/usr/share/xpdf/xpdf-chinese-s

11、implified -s flashversion=9项目目录及源码工程目录大致如下：另外，在lib下需要加入JodConverter压缩包中lib目录下的jar包，全部复制进去即可。ConvertServlet的servlet处理类代码如下：package org.edc.test.servlet;import java.io.File;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.
