Java conversion to various file types in Word

One of the programs used to Poi,jacob,openoffice,icepdf,itext bag, you can search the Internet.

PS: When using OpenOffice to convert a PDF to a picture, the prerequisite is to have the OpenOffice software installed locally and to turn on the service:

After installing OpenOffice

1. After installing OpenOffice, enter the default installation directory.

CD C:\Program Files (x86) \openoffice 4\program

Perform

Soffice-headless-accept= "SOCKET,HOST=127.0.0.1,PORT=8100;URP;"-nofirststartwizard

2. See if the installation is successful

2.1 View the port corresponding to the PID

Netstat-ano|findstr "8100"

2.2 View the PID corresponding service program name

Tasklist|findstr "IPD Value"

Not much to say, directly on the code:
