如何将JEditorPane另存为pdf？

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class HtmlToPdfConverter {
    public static void main(String[] args) {
        String htmlFilePath = "path/to/html/file.html";
        String pdfFilePath = "path/to/save/pdf/file.pdf";

        try {
            // 创建PDF文档对象
            Document document = new Document();
            PdfWriter.getInstance(document, new FileOutputStream(pdfFilePath));
            document.open();

            // 读取HTML文件内容
            BufferedReader br = new BufferedReader(new FileReader(htmlFilePath));
            String line;
            StringBuilder htmlContent = new StringBuilder();
            while ((line = br.readLine()) != null) {
                htmlContent.append(line);
            }
            br.close();

            // 将HTML内容写入PDF文档
            HTMLWorker htmlWorker = new HTMLWorker(document);
            htmlWorker.parse(new StringReader(htmlContent.toString()));

            document.close();
            System.out.println("PDF文件已成功创建！");
        } catch (DocumentException | IOException e) {
            e.printStackTrace();
        }
    }
}
