The realization of Baidu Library--java use Openoffice,word to PDF

The main function of Baidu Library is to upload the Word document, transcoding into PDF format and then show it. There are four ways to do this:

method One: Use Apache Pio to read the doc file, and then convert the HTML file into a jsoup format HTML file, and finally use Itext to convert the HTML file into PDF. 

Method 2: Use Jdoctopdf to implement, this is a package good package, you can convert the doc to pdf,html,xml and other formats, call very convenient
you need to be aware of writing problems with Chinese fonts. 

Method 3: Using Jodconverter to invoke OpenOffice's service to convert, OpenOffice has a version of each platform, so this approach is as cross-platform as method 1. 
after installation to start OpenOffice Services, the specific starting method please Google

Method 4: One of the best methods, but requires a window environment, and the speed is the slowest need to install Msofficeword and SaveAsPDFandXPS.exe (a plugin for Word to convert Word to PDF)
The Office version is 2007 because Saveaspdfandxps is a plugin developed by Microsoft for office2007 and above

Here we adopt the third method, because of its cross-platform properties and simple and convenient operation.

 windows: 1 2 3. Download Jodconverter, and import all the jar packages under the Lib folder into Linux:  1. First install the OpenOffice for   Linux, can be downloaded to the official website can also use the command. Command download: wget http:  // sourceforge.net/ Projects/openofficeorg.mirror/files/4.1.1/binaries/zh-cn/apache_openoffice_4.1.1_linux_x86-64_install-rpm_ zh-cn.tar.gz   tar -xzvf apache_openoffice_4.1.1_linux_x86-64_      Install-rpm_zh-cn.tar.gz cd zh -CN CD RPMS RPM -ivh *.rpm  2. It is also possible to invoke command startup in Linux, but to tell you that it can be set to boot or boot with Tomcat, So that the transcoding program starts frequently.
