[英]HTML to PDF using Flying Saucer: Internal CSS showing in PDF page
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
{
try {
StringBuffer buffer = new StringBuffer();
buffer.append("<html>");
buffer.append("<head>");
buffer.append("<style type='text/css'>");
buffer.append("@page {background-color: #f0f0f0;}");
buffer.append("</style>");
buffer.append("</head>");
buffer.append("<body>");
buffer.append("<h2>Hello</h2>");
buffer.append("</body>");
buffer.append("</html>");
DocumentBuilder docBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = docBuilder.parse(new StringBufferInputStream(buffer.toString()));
OutputStream os = response.getOutputStream();
ITextRenderer renderer = new ITextRenderer();
renderer.setDocument(doc, null);
renderer.layout();
renderer.createPDF(os);
os.close();
}
What happens when it displays the pdf the css works correctly and displays a gray background, however, it displays the following text:@page {background-color: #f0f0f0;}Hello. 当它显示pdf时,css可以正常工作并显示灰色背景,但是会显示以下文本:@page {background-color:#f0f0f0;}您好。 How do I get the styling text to stop showing up in the pdf? 如何获取样式文本以使其停止显示在pdf中?
If you replace: 如果您更换:
@page {background-color: #f0f0f0;}
by 通过
<!--
@page {background-color: #f0f0f0;}
-->
then the <style>
tag will recognize the style, but the style won't "count" as HTML because we've put it inside a comment. 那么<style>
标记将识别该样式,但是该样式不会“计数”为HTML,因为我们已将其放入注释中。
