//在每页结束的时候把“第x页”信息写道模版指定位置

headAndFootPdfContent.restoreState();

}
}
public void onCloseDocument(PdfWriter writer, Document document) {
//关闭document的时候获取总页数，并把总页数按模版写道之前预留的位置
tpl.beginText();
tpl.setFontAndSize(bfChinese, 12);
tpl.showText("页,共" + Integer.toString(writer.getPageNumber() - 1) + "页--");
tpl.endText();
tpl.closePath();//sanityCheck();
}
}
方法调用如下：下document的open之前写：
//设置pdf每页的页眉和页脚
writer.setPageEvent(new HeadFootInfoPdfPageEvent("页眉的名称",stolist.get(0).getDate("stsu_data").toString(),"入",stsu.getStr("stsu_code")));
