IText7 html2pdf页脚CSS不起作用

问题描述：

我无法在HTML和CSS下面的结果PDF中看到页脚.此代码在 IText版本2 中可以正常使用.

I am not able to see footer in resultant PDF for below HTML and CSS. This code works fine with IText version 2.

在 IText版本7 中，显示页眉和页脚的方式是否发生了变化?还是缺少新版本所需的任何配置?

Does the way to show header and footer is changed in IText version 7? or am I missing any configuration required for newer version?

谢谢.

Java代码

public void createPdf(String src, String dest, String resources) throws IOException {
try {
        FileOutputStream outputStream = new FileOutputStream(dest);

        WriterProperties writerProperties = new WriterProperties();
        //Add metadata
        writerProperties.addXmpMetadata();

        PdfWriter pdfWriter = new PdfWriter(outputStream, writerProperties);

        PdfDocument pdfDoc = new PdfDocument(pdfWriter);
        pdfDoc.getCatalog().setLang(new PdfString("en-US"));

        // pdf conversion
        ConverterProperties props = new ConverterProperties();

        MediaDeviceDescription mediaDeviceDescription =
            new MediaDeviceDescription(MediaType.PRINT);
        props.setMediaDeviceDescription(mediaDeviceDescription);

        HtmlConverter.convertToPdf(new FileInputStream(src), pdfDoc, props);
        pdfDoc.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

HTML内容

<html>
<head>
    <meta charset="UTF-8"/>

    <style type="text/css" media="print">

        #footer {
            display: block;
            position: running(footer);
            color:gray;
            font-size: 50%
        }

        @page {
            @bottom-center {
                content: element(footer);
            }
            margin-bottom : 1in;
            size: 6in 6in;
        }


    </style>
</head>
<body>
<div id="footer">
This is the text that goes at the bottom of every page.
</div>

您所做的一切正确.它对您不起作用，因为仅在最新版本 iText 7.1.2 中添加了运行元素(position: running(..)和content: element(..)属性)支持.它于4月底发布.

You're doing everything right. It wasn't working for you because running elements (position: running(..) and content: element(..) properties) support is added only in the latest version, iText 7.1.2. It was released in the end of April.
