Question

我在java我的应用程序中使用PDFtron.jar将html转换为pdf除了bootstrap css在转换时不渲染（PDFTron在转换为pdf时不理解bootstrap css）时，每个东西都正常工作，因为例如下面的代码不被理解通过pdftron，我在我的pdf中获得了两个div。

<div class="col-xs-12 info-details visible-xs">Visible for xs screen</div>
<div class="col-xs-12 info-details hidden-xs">Visible for non xs screen</div>

以下是转换htmlToPdf

的代码

    if (System.getProperty("java.library.path").indexOf(support.config.getTomcatHome() + File.separator + "lib") == -1)
            {
                System.setProperty("java.library.path", System.getProperty("java.library.path") + File.pathSeparatorChar + support.config.getTomcatHome() + File.separator
                        + "lib" + File.pathSeparatorChar + support.config.getTomcatHome() + File.separator
                        +  "lib"  + File.separator + "PDFNet.jar");
                java.lang.reflect.Field fieldSysPath = ClassLoader.class.getDeclaredField("sys_paths");
                fieldSysPath.setAccessible(true);
                fieldSysPath.set(null, null);
                Util.Log("PDFNet.jar loaded");
            }

            OS = System.getProperty("os.name").toLowerCase();
            PdfViewerLicense.initialize();
            PDFNet.setTempPath(pdfFolderPath+File.separator);
            doc = new PDFDoc();
            converter = new HTML2PDF();
            if(OS.indexOf("win") < 0)
            {
                HTML2PDF.setModulePath(support.config.getTomcatHome() + File.separator + "lib"  + File.separator +"html2pdf.so" ); 
            }
            converter.setLandscape(false);
            converter.setPaperSize(PrinterMode.e_A4);
            converter.insertFromHtmlString(html);
            if (converter.convert(doc)){
                doc.save(output_pdf_path, SDFDoc.e_linearized, null);
                result = true;
            }else {
                Util.Log("PDFTron Conversion failed. HTTP Code: " + converter.getHTTPErrorCode() + "\n" + converter.getLog());
            }
        }

如果内存服务，html2pdf无法获取外部资源。您需要将引导程序CSS文件和字体CSS文件的内容嵌入到某些<style>标记中
