iText 5页眉和页脚

1. 创建一个MyPageEventListener类，该类扩展了 PdfPageEventHelper
2. 将页面事件侦听器添加到PdfWriter对象
3. 在MyPageEventListener类的 onEndPage 方法中，放置页眉/页脚的代码

例：

public class MyPageEventListener extends PdfPageEventHelper {  . . .  @Override  public void onEndPage(PdfWriter writer, document document) {     //pre skeleton to write page header     PdfPTable tbl = new PdfPTable(3);     tbl.addCell("1st cell");     tbl.addCell("2nd cell");     tbl.addCell("3rd cell");     float x = document.leftMargin();     float hei = getMyHeaderHeight(); //custom method that return header's height      //align bottom between page edge and page margin     float y = document.top() + hei;     //write the table     tbl.writeSelectedRows(0, -1, x, y, writer.getDirectContent());  }    }

注册收听者只需

writer.setPageEvent(new MyPageEventListener());
