Java iText页脚

Question

我正在尝试使用JSP页面生成PDF,我的编码大纲如下,

Document document           = new Document(PageSize.A4,70/*Left*/,70/*Right*/,140/*Top*/,30/*Bottom*/);

response.setContentType("application/pdf" );
response.setHeader("Content-Disposition","inline; filename=vishwa-mandate.pdf");

PdfWriter.getInstance(document, response.getOutputStream());
document.open();

HeaderFooter footer = new HeaderFooter(new Phrase("This is page "), true);
document.setFooter(footer);

/* PAGE 01 */

document.newPage(); 

/* PAGE 02 + */

document.close();

一旦我明确调用,页面页脚不适用于PAGE 01 document.newPage();
如何在整个文档中获取页脚？

Answer 1

应在打开文档之前调用setFooter(页脚)

更正后的代码如下

HeaderFooter footer = new HeaderFooter(new Phrase("This is page "), true);
document.setFooter(footer);

// Document should open after setting the footer
document.open();
