我使用 Jtidy 和 java 将文档从 html 转换为 pdf 的问题是，当我转换 pdf 时，样式未应用于文档。当我尝试其他解决方案（Jsoup、HTMLworker、xmlWorker）时，文档也格式不正确。

    private static ByteArrayOutputStream html2Xhtml(String html) {
    Tidy tidy = new Tidy();
    tidy.setShowWarnings(false);
    tidy.setXmlTags(false);
    tidy.setInputEncoding("UTF-8");
    tidy.setOutputEncoding("UTF-8");
    tidy.setXHTML(true);
    tidy.setMakeClean(true);
    tidy.setForceOutput(true);
    ByteArrayOutputStream fileFit = new ByteArrayOutputStream();
    tidy.parseDOM(new ByteArrayInputStream(html.getBytes()), fileFit);
    return fileFit;
}

public @ResponseBody byte[] SavePdf(
        @RequestParam("documentContent") final Object documentContent)
        throws  IOException {
    ByteArrayOutputStream file = new ByteArrayOutputStream();
    ITextRenderer renderer = new ITextRenderer();
    String xhtml = html2Xhtml(documentContent.toString()).toString();
    renderer.setDocumentFromString(xhtml);
    renderer.layout();
    try {
        renderer.createPDF(file);
    } catch (com.lowagie.text.DocumentException e) {
        log.info(e.getMessage(), e);
        e.printStackTrace();
    }
    return file.toByteArray();
}

这是 html 代码的一部分：
