preface

After investigation, I found that there are many solutions on the Internet. Word and PDF can be converted perfectly on Windows platform, but most businesses require to run on Linux, and windows-based methods cannot be transplanted to Run on Linux. After verification, most of the existing Methods of converting Word documents into PDF on Linux have the problem of inconsistency between PDF and Word format (such as inconsistency in page number between PDF and Word, more compact text arrangement, etc.). Therefore, the main goal of this paper is to solve the problem of inconsistent format layout after Word is converted to PDF on Linux platform. First, the conclusion is that the format of most test case documents is basically consistent after conversion, but there are a few inconsistent problems. And package the Java project into a JAR package and call the command line test on the Linux platform to pass.

Convert Word to PDF for Windows platform

import win32com  # python -m pip install pypiwin32
from win32com.client import Dispatch
import sys

def word2pdf(file_path='/ Documents /4- Business Meeting Service Agreement _20191105 Guangzhou) :
	word = Dispatch('Word.Application')
	word.Visible = 0 # background run, do not display
	word.DisplayAlerts = 0  # without warning
	path = sys.path[0] + file_path
	doc = word.Documents.Open(FileName=path, Encoding='gbk')
	doc.SaveAs(path[:-5] +'_pdfed.pdf'.17) # TXT =4, HTML =10, docx=16, PDF =17
	doc.Close()
	word.Quit()
	print("Word2Pdf conversion completed, PDF file and Word in the same directory.")

if __name__ == '__main__':
	# word2PDF ('/ Documents /1- Technical Service contract.docx ')
	file_path = sys.argv[1]
	print(file_path)
	word2pdf(file_path)

Linux Platform Word to PDF

Yum install unoconv use: unoconv -f PDF xxx.docx

Sudo apt-get install cups-pdf use oowriter-convert-to PDF :writer_pdf_Export xxx.docx

3. Test with LibreOffice: Soffice –headless –invisible –convert-to PDF XXX.docx

4. Convert WORD to PDF by Java programming with Apose-Words-15.8.0 tool Hacked (Pojie) version. (It is recommended that the format change of Word is the least after it is converted to PDF.)

Eclipse project directory structure :(complete project source code and packaged jar package are at the end of this article, jar package tests can be called directly)

The jar package can only be placed in the same directory as the word document to be converted, and the generated directory can only be placed in the same directory, which is related to Java getResourceAsStream usage.

GetResourceAsStream reads file paths only within the project’s source folder, including the project SRC root directory, and anywhere in the class package, but this method does not work if the configuration file path is in a folder other than the source folder. Quote from: www.iteye.com/blog/riddic…

GetResourceAsStream: file_path = “C:\ Users\ 16616\ Desktop\ xxx. docx”; word = TestWord.class.getClassLoader().getResourceAsStream(file_path); Document doc = new Document(word); Document doc = new Document(file_path);

Finally, the source code:

Will containJava project packaging for third-party JAR packagesAnd use the command line to pass the jar package:

1. First, Eclipse packages projects that already contain third-party JAR packages:

选File/Export… thenJava/Runnable JAR fileAnd thenSelect the class that has main() to run, chooseextract required libraries into generated JAR.

  1, no parameter Open the jar package directory and enter java-jar xxx.jar2Open the jar package directory and enter the java-jar xxx.jar parameter1parameter2... (Arguments are separated by Spaces) corresponding to the main function:public static void main(String[] args) {	    
	    String sourcePath = args[0];1 / / parameter
	    String targetPath = args[1];2 / / parameter
	}
