java - 如何在 Apache FOP 中从 Java 代码配置字体？

Question

link说从 java 代码配置字体不是“容易”的。我该如何实现这一目标？我在使用法语和日语等国际语言呈现某些 HTML 时遇到问题。

WARNING: Font "Symbol,normal,700" not found. Substituting with "Symbol,normal,400".

WARNING: Font "ZapfDingbats,normal,700" not found. Substituting with "ZapfDingbats,normal,400". 

生成的 PDF 结果被损坏。

更新:

我的 Html 包含法语单词，例如“Modifié Créée le Propriétaire”

File file = new File("C:\\Users\\me\\Desktop\\Test.html");


fopFactory = FopFactory.newInstance();
foUserAgent = fopFactory.newFOUserAgent();


String fileName = file.getAbsolutePath().substring(file.getAbsolutePath().lastIndexOf("\\")+1,file.getAbsolutePath().lastIndexOf("."));
        String workspacePath = file.getAbsolutePath().substring(0,file.getAbsolutePath().lastIndexOf("\\"));
        File xsltfile = new File("xhtml2fo.xsl");
        StreamSource source = null;
        source = new StreamSource(file);
        StreamSource transformSource = new StreamSource(xsltfile);
        ByteArrayOutputStream outStream = new ByteArrayOutputStream();


        Transformer xslfoTransformer = null;
        TransformerFactory fac = TransformerFactory.newInstance();
        xslfoTransformer = fac.newTransformer(transformSource);
        xslfoTransformer.setErrorListener(this);

        Fop fop;
        fop = fopFactory.newFop(MimeConstants.MIME_PDF, foUserAgent, outStream);
        // Resulting SAX events (the generated FO)
        Result res = new SAXResult(fop.getDefaultHandler());
        xslfoTransformer.transform(source, res);

        output = new File(workspacePath + File.separator + fileName + ".pdf");
        OutputStream out = new java.io.FileOutputStream(output);
        out = new java.io.BufferedOutputStream(out);
        FileOutputStream str = new FileOutputStream(output);
        str.write(outStream.toByteArray());
        str.close();

我正在使用 Antennahouse 提供的 XSLT 将 HTML 标记转换为 FO 标记。

示例代码。

/** The Constant FOP_CONFIG. */
    private static final String FOP_CONFIG = "pdf.fop.cfg.xml";

fopFactory = FopFactory.newInstance();
                    // for image base URL
                    String serverPath = request.getSession().getServletContext().getRealPath("/");
                    //disable strict validatetion
                    fopFactory.setStrictValidation(false);
                    fopFactory.setBaseURL(serverPath);
                    // for fonts base URL
                    fopFactory.getFontManager().setFontBaseURL(serverPath);
                    // read custom font setting
                    StreamSource configSrc = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream(PDFComponentFactory.FOP_CONFIG));
                    DefaultConfigurationBuilder cfgBuilder = new DefaultConfigurationBuilder();
                    Configuration cfg = cfgBuilder.build(configSrc.getInputStream());
                    fopFactory.setUserConfig(cfg);

希望对您有帮助。
