word文档转pdf java

可以使用Apache POI和iText库来实现将Word文档转换为PDF格式的Java代码。具体实现可以参考以下代码：

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.xwpf.converter.pdf.PdfConverter;
import org.apache.poi.xwpf.converter.pdf.PdfOptions;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class WordToPdfConverter {

    public static void main(String[] args) {
        String inputFilePath = "input.docx";
        String outputFilePath = "output.pdf";
        try {
            // Load input Word document
            XWPFDocument document = new XWPFDocument(new FileInputStream(inputFilePath));
            
            // Prepare PDF options
            PdfOptions options = PdfOptions.create();
            
            // Convert Word document to PDF
            PdfConverter.getInstance().convert(document, new FileOutputStream(outputFilePath), options);
            
            // Close document
            document.close();
            
            System.out.println("Word document converted to PDF successfully!");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请注意，您需要在项目中添加以下依赖项：
