Java calls py or exe files to implement Word to PDF

Preface

Once at work, my friend complained that it was too troublesome to implement word to pdf in Java. I had a sudden inspiration to call python, and I just wanted to implement conversion operations in Python.

Development Environment

Java：JDK1.8

python：3.12

Code

Python code

import docx2pdf
import sys
import glob
import os
import comtypes
import 
 
 
def w2ps(d):
    word_file = d
    pdf_file = ('.docx', '.pdf').replace('.doc', '.pdf')
    (word_file, pdf_file)
    print(f"Conversion is complete，PDFThe file has been saved as：{pdf_file}")
 
 
def each():
    # Get the current working directory    current_directory = ()
 
    # Use glob to find all .doc files    doc_files = ((current_directory, '*.doc'))
    doc_files1 = ((current_directory, '*.docx'))
 
    # traverse the file list and print the file path    if len(doc_files) &gt; 0:
        # Initialize Word Application        word = ('')
         = False  # Do not display the Word interface        for file_path in doc_files:
            doc = (file_path)
            # Export as PDF            (file_path.replace('.doc', '.pdf'), FileFormat=17)  #17 is PDF format code            ()
        ()
        # w2ps(file_path)
    for file_path in doc_files1:
        w2ps(file_path)
 
 
if __name__ == "__main__":
    if len() &gt; 1:
        w2ps([1])
    else:
        each()
    ()

Java code

import ;
 
public class PythonCaller {
 
    public static void main111(String[] args) {
        String pythonScriptPath = "D:\\WorkSpace\\python\\pycorrector-master\\shany\\"; // Path to Python scripts        String wordFilePath = "E:\\Create a new folder (22)\\Problem troubleshooting.docx"; // The path to the Word file to be converted 
        try {
            String command = "python " + pythonScriptPath + " \"" + wordFilePath+"\"";
            Process process = ().exec(command);
 
        } catch (IOException e) {
            ();
        }
    }
 
    public static void main(String[] args) {
        String executablePath = "D:\\New folder\\a\\"; // Replace with the actual path of your file        String wordFilePath = "E:\\Create a new folder (22)\\Problem troubleshooting.docx"; // Replace with your Word file path 
        try {
            // Pass the Word file path as a command line parameter to            String[] command = {executablePath, wordFilePath};
            Process process = ().exec(command);
 
            // Wait for the process to complete            int exitCode = ();
            ("Process exited with code " + exitCode);
 
        } catch (IOException | InterruptedException e) {
            ();
        }
    }
}

Remark

Later, in order to prevent the lack of three-party dependencies, the python file was packaged separately into an exe file. An additional call to the exe file is added to the Java code.

Because the class library for doc to pdf was not found, the processing logic here is changed to if it is a doc file, Microsoft Word will be called for conversion.

When packaging py is exe, you must specify the import. The packaging command is as follows

pyinstaller --onefile --noconsole --hidden-import=

This command parsing: convert a file called exe, introduce it additionally, and does not display the command line window (--noconsole)

expand

I wrote an additional PDF to Word, and the functions and usage are basically the same.

from pdf2docx import Converter
import sys
import glob
import os
 
 
def pdf_to_word(pdf_path, word_path):
    cv = Converter(pdf_path)
    (word_path, start=0, end=None)
    ()
 
 
def p2ws(file_path):
    pdf_file = file_path
    word_file = file_path.replace('.pdf', '.docx')
    pdf_to_word(pdf_file, word_file)
    print(f"Conversion is complete，WORDThe file has been saved as：{pdf_file}")
 
 
def each():
    # Get the current working directory    current_directory = ()
 
    # Use glob to find all .doc files    doc_files = ((current_directory, '*.pdf'))
 
    # traverse the file list and print the file path    for file_path in doc_files:
        p2ws(file_path)
 
 
if __name__ == "__main__":
    if len() &gt; 1:
        p2ws([1])
    else:
        each()
