//页头信息左面

headAndFootPdfContent.showTextAligned(PdfContentByte.ALIGN_LEFT, riqi[0] + "年" + riqi[1] + "月" + riqi[2] + "日",

//文档页脚信息设置

float y1 = document.bottom(-35);

//页脚信息左面

headAndFootPdfContent.showTextAligned(PdfContentByte.ALIGN_LEFT, "储运部负责人：", document.left() + 100, y, 0);

//页脚信息中间

headAndFootPdfContent.showTextAligned(PdfContentByte.ALIGN_CENTER, " 库管员： ", (document.right() + document.left()) / 2, y, 0);

//页脚信息右面

headAndFootPdfContent.showTextAligned(PdfContentByte.ALIGN_RIGHT, " 经手人：", document.right() - 100, y, 0);

//添加页码

//页脚信息中间

headAndFootPdfContent.showTextAligned(PdfContentByte.ALIGN_CENTER, "--第" + document.getPageNumber(),

(document.right() + document.left()) / 2, y1, 0);

//在每页结束的时候把“第x页”信息写道模版指定位置

headAndFootPdfContent.addTemplate(tpl, (document.right() + document.left()) / 2 + 15, y1);//定位“y页” 在具体的页面调试时候需要更改这xy的坐标

headAndFootPdfContent.endText();

headAndFootPdfContent.restoreState();

} catch (Exception de) {

de.printStackTrace();

}

}

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")));
