Four ways to export Word documents in Java

Exporting Word documents in Java can be achieved through a variety of libraries and methods. Here are some commonly used methods:

1. Use Apache POI

Apache POI is a powerful library that can be used to read and write files in Microsoft Office format, including Word documents.

Sample code:

import ;
import ;

import ;
import ;

public class WordExport {
    public static void main(String[] args) {
        XWPFDocument document = new XWPFDocument();
        XWPFParagraph paragraph = ();
        ().setText("Hello, World!");

        try (FileOutputStream out = new FileOutputStream("")) {
            (out);
        } catch (IOException e) {
            ();
        }
    }
}

2. Use Docx4j

Docx4j is a Word processing library implemented in Java and supports DOCX format.

Sample code:

import org.;
import org.;
import org.;

public class Docx4jExample {
    public static void main(String[] args) {
        WordprocessingMLPackage wordMLPackage = ();
        ObjectFactory factory = new ObjectFactory();
        P paragraph = ();
        ().add(("Hello, Docx4j!"));
        ().getContent().add(paragraph);

        try {
            (new (""));
        } catch (Exception e) {
            ();
        }
    }
}

3. Use JODConverter

JODConverter converts HTML or other formats to Word documents through LibreOffice or OpenOffice.

Sample code:

import ;

import ;

public class JODConverterExample {
    public static void main(String[] args) {
        (new File("")).to(new File("")).execute();
    }
}

4. Use the FreeMarker template

FreeMarker can generate templates for Word documents and generate the final document by replacing placeholders.

Sample code:

import ;
import ;
import ;

import ;
import ;
import ;
import ;
import ;

public class FreeMarkerExample {
    public static void main(String[] args) {
        Configuration cfg = new Configuration(Configuration.VERSION_2_3_31);
        (, "/templates");

        Map<String, Object> data = new HashMap<>();
        ("title", "Hello FreeMarker");
        ("content", "This is a generated Word document.");

        try {
            Template template = ("");
            FileWriter out = new FileWriter(new File(""));
            (data, out);
            ();
        } catch (IOException | TemplateException e) {
            ();
        }
    }
}
