Java uses openoffice to convert doc docx to pdf instance code

This paper mainly studies Java programming using openoffice to doc, docx into pdf implementation code, as follows.

1. The software you need

OpenOffice , JodConverter

2. Start OpenOffice services

soffice ="socket,host=127.0.0.1,port=8100 "soffice-headless-accept ="socket,host=127.0.0.1,port=8100" soffice-headless-accept ="socket,host=127.0.0.1,port=8100" urp;" .

In fact, for my project, transcoding is done only occasionally, but when the OpenOffice transcoding service is started, the process (process name is soffice.exe) will always exist and occupy about 100M memory, which feels very wasteful. So I figured out a way to call the command to execute the service directly in the Java code, and then kill the process when the transcoding is completed. This will be explained in the JAVA code below.

So, actually, step 2 can be skipped

3. Add jar packages related to JodConverter to the project

After unzipping JodConverter, add all the jar packages below lib to the project

Note: Install openoffice

4. Here are the key points. See Java code analysis for details
