Java uses openoffice to convert doc and docx into pdf instance code, openofficedocx

This article focuses on Java programming using openoffice to convert doc and docx into pdf implementation code, as detailed below.

1. Required Software

OpenOffice, JodConverter

2. Start the OpenOffice Service

When I go online to check how to use OpenOffice for transcoding, I need to first use cmd to start a soffice service. The startup command is: soffice-headless-accept = "socket, host = 127.0.0.1, port = 8100; urp ;".

Memory) will always exist, and occupy about MB of memory, it feels very wasteful.So I thought of a way to directly call the commands that execute the service in Java code, and then directly kill the process when transcoding is complete. It will be explained in the following JAVA code.

Therefore, you can skip this step 2nd directly.

3. Add jar packages related to JodConverter to the project.

After extracting JodConverter, add all the jar packages under lib to the project.

Note: Install openoffice

4. The following is the focus. For details, see Java code parsing.
