如何在下载/导出时指定pdfbox.apache文件名？

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;

import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class PdfExportUtil {
    public static void exportPdf(HttpServletResponse response) throws IOException {
        // 创建一个空白PDF文档
        PDDocument document = new PDDocument();
        PDPage page = new PDPage();
        document.addPage(page);

        // 设置文件名
        String filename = "your_filename.pdf";

        // 设置响应头
        response.setContentType("application/pdf");
        response.setHeader("Content-Disposition", "attachment; filename=" + filename);

        // 导出PDF
        document.save(response.getOutputStream());

        // 关闭文档
        document.close();
    }
}
