Java converts word to PDF with OpenOffice

First, Software Installation and Jar Package Download

The official website is as follows (English):

OpenOffice http://www.openoffice.org/

Jodconverter http://sourceforge.net/projects/jodconverter/files/JODConverter/

You can also Baidu to search, on the csdn above can also download to the required package.

jodconverter:http://download.csdn.net/download/yali1990515/4443791

After decompression, all the jar packages under the directory are placed under the project Lib or referenced in a way that invokes these jar packages.

OpenOffice:

Http://www.baidu.com/link?url= Nprmkalzg44nn-spouwjsrrlgohs5qzn7aejtc2ccsukjjwo6rxfjhh5g4kw0ckzm4zjs2kr2grdwsq8tarcswjb08oujq_ih4wqeeml_lm

Install after download, I install the path to C:/openoffice 4

Second, Start the service

This part will be implemented as thread-initiated in the program, without the need for additional cmd windows to invoke the system to start the service.

The implementation starts the service and shuts down the service after all operations are completed. In other words, each execution of the program goes through the process of service startup and service shutdown. If you think this is an impact on system performance, you can also start the OpenOffice service separately.

Third, Program Code

*/

Public Static int office2pdf (string sourcefile, String destfile) {

Try {

File Inputfile = new file (sourcefile);

if (!inputfile.exists ()) {

return -1;//The source file is not found, returns-1

}

If the destination path does not exist, the path is created

File OutputFile = new file (destfile);

if (!outputfile.getparentfile (). exists ()) {

Outputfile.getparentfile (). Mkdirs ();

}

Start the OpenOffice service

String command = "C:/openoffice 4/program/soffice.exe-headless-accept=\" socket,host=127.0.0.1,port=8100;urp;\ "";

Process Pro = Runtime. GetRuntime (). exec (command);

Connect to a OpenOffice.org instance running on port 8100

Openofficeconnection connection = new socketopenofficeconnection ("127.0.0.1", 8100);

Connection.connect ();

Convert

Documentconverter converter = new openofficedocumentconverter (

connection);

Converter.convert (Inputfile, outputFile);

Close the connection

Connection.disconnect ();

Shutting down the process of the OpenOffice service

Pro.destroy ();

return 0;

} catch (FileNotFoundException e) {

E.printstacktrace ();

return -1;

} catch (IOException e) {

E.printstacktrace ();

}

return 1;

}

Public Static void Main (string[] args) {

String Source = "D:\\trs/trswcmv7\\protect\\p0201501\\p020150109\\p020150109485061451482.doc";

String dest = "C:\\1.pdf";

int result = office2pdf(source, dest);

System. out. println (result);

}

}

You can comment out the annotations appropriately.

Cause: The newly installed OpenOffice has not been registered, and when you use the program to call Soffice.exe will be blocked, and then connection refused error.

Workaround: Find this Soffice.exe program installed on the computer, double-click Open, after registration can be used normally.
