javascript - xhtmlrenderer xhtml 到 pdf 字体问题，甚至不能使用字体系列 : Verdana;

Question

我正在使用 flyingSaucer 从 HTML 和 CSS 生成 PDF。

其余代码工作得很好，除了字体的东西。以下是我正在使用的代码。

public void convertHtmlToPdf(String html, String css, OutputStream out) {
    try {
        html = correctHtml(html);
        html = getFormedHTMLWithCSS(html, css);

        HtmlCleaner cleaner = new HtmlCleaner();
        TagNode rootTagNode = cleaner.clean(html);
        CleanerProperties cleanerProperties = cleaner.getProperties();
        XmlSerializer xmlSerializer = new PrettyXmlSerializer(cleanerProperties);
        String cleanedHtml = xmlSerializer.getAsString(rootTagNode);


        File fontFile = new File("/omegaengineeringservices/Verdana.ttf");
        FontFactory.register(fontFile.getAbsolutePath());

        ITextRenderer r = new ITextRenderer();
        FontResolver resolver = r.getFontResolver();

        r.getFontResolver().addFont(fontFile.getAbsolutePath(), BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED);
        r.setDocumentFromString(cleanedHtml);

        r.layout();
        r.createPDF(out);
        r.finishPDF();

    } catch (Exception e) {
        e.printStackTrace();
        logger.error(e.getMessage(), e);
    }
}

我也在我的 CSS 中添加了相同的字体。

.manual-body-center{
        width:100%;
        font-family: Verdana;
    }

因此，我得到一个错误，

ExceptionConverter: java.io.IOException: /omegaengineeringservices/Verdana.ttf not found as file or resource.

给定文件路径有问题/omegaengineeringservices/Verdana.ttf

您需要在那里提供有效的路径，有关详细信息，请参阅flyingsaucer 用户指南。在如何添加自定义或特定字体？部分，有详细的示例。
