Convert Word document to PDF using Java

Convert Word document to PDF using Java

First create a new Maven project, and then create a new lib folder under the same level as src

Download the aspose-words-15.8.0-jdk16.jar package, the download address is as follows

Link: https://pan.baidu.com/s/1tguBmQK3XIypH5KAjQyG-A?pwd=5ar5 Extraction code: 5ar5

After the download is complete, put this package in the lib folder, then right click and select Add as Library

Then create a new license.xml file in the resources folder, the content is as follows

<License>
<Data>
<Products>
<Product>Aspose.Total for Java</Product>
<Product>Aspose.Words for Java</Product>
</Products>

</License>

Then create a new WordToPdfUtils.java, which provides a method of converting pdf to the outside world

package com.szx.util;

import com.aspose.words.Document;
import com.aspose.words.License;

import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;

public class WordToPdfUtils {
    
    
    private static boolean getLicense() {
    
    
        boolean result = false;
        try {
    
    
            InputStream is = WordToPdfUtils.class.getClassLoader().getResourceAsStream("license.xml");
            License aposeLic = new License();
            aposeLic.setLicense(is);
            result = true;
        } catch (Exception e) {
    
    
            e.printStackTrace();
        }
        return result;
    }

    public static void docToPdf(String wordPath, String pdfPath) {
    
    
        if (!getLicense()) {
    
     // 验证License 若不验证则转化出的pdf文档会有水印产生
            return;
        }
        try {
    
    
            long old = System.currentTimeMillis();
            File file = new File(pdfPath); //新建一个pdf文档
            FileOutputStream os = new FileOutputStream(file);
            Document doc = new Document(wordPath); //Address是将要被转化的word文档
            doc.save(os, com.aspose.words.SaveFormat.PDF);//全面支持DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, EPUB,
            // XPS, SWF 相互转换
            long now = System.currentTimeMillis();
            os.close();
            System.out.println("共耗时：" + ((now - old) / 1000.0) + "秒"); //转化用时
        } catch (Exception e) {
    
    
            e.printStackTrace();
        }
    }
}

Use the docToPdf method to convert word files into pdf. Note that the address of the word file must be a real local file address, and the address of the pdf file indicates the location where the generated file will be placed

public class test {
    
    
    public static void main(String[] args) {
    
    
        String wordUrl = "D:\\apps\\测试.docx";
        String pdfUrl = "D:\\apps\\测试.pdf";
        WordToPdfUtils.docToPdf(wordUrl,pdfUrl);
    }
}

After running successfully, the effect is as follows

Check if there is a pdf file in D:\apps
