jar包和openoffice的下载
最好都到官网下载或者sourceforge下载，不要在csdn或者其他的地方下载，因为很多都被人重新打包过导致各种问题。
- pdfbox的下载地址
只需要pdfbox-1.8.13.jar，fontbox-1.8.13.jar，用来pdf转图片
- openoffice的下载地址
- commons-loging.jar的下载（你如果下载过poi，你会发现里面也有）
- JODConverter的下载地址
用来连接openoffice
打开openoffice
2.启动OpenOffice的服务
安装完openoffice，安装服务
cd C:\Program Files (x86)\OpenOffice 4\program
执行
soffice -headless -accept=”socket,host=127.0.0.1,port=8100;urp;” -nofirststartwizard
查看是否安装成功，查看端口对应的pid
netstat -ano|findstr "8100"
查看pid对应的服务程序名
tasklist|findstr "pid值"
若有对于值，说明服务启动成功
代码
（我的代码都是针对于项目的doc文件夹下面的文件，如果要直接用，需要新建一个doc文件夹，并把文件放在下面，若要换成其他路径，需要修改tmpDir）
附该代码项目的下载地址
