public class App {    public static void main( String[] args ) throws Exception {        Document document = new Document(PageSize.A4,50,50,50,50);        PdfWriter writer = PdfWriter.getInstance(document,new FileOutputStream("/home/hzq/a.pdf"));        BaseFont baseFont = BaseFont.createFont("simhei.ttf",BaseFont.IDENTITY_H,BaseFont.EMBEDDED);        Font font = new Font(baseFont,12);        Rectangle rect = new Rectangle(36, 54, 559, 788);        rect.setBorderColor(BaseColor.BLACK);        writer.setBoxSize("art", rect);        HeaderFoot headerFoot = new HeaderFoot();        writer.setPageEvent(headerFoot);        document.open();        Paragraph paragraph = new Paragraph("This is First Page 第一页",font);        document.add(paragraph);        document.newPage();        document.add(new Paragraph("This is Second Page 第二页",font));        document.newPage();        document.add(new Paragraph("This is Second Page 第三页",font));        document.close();    }}

HeaderFoot类：

public class HeaderFoot extends PdfPageEventHelper {    private String header;    private PdfTemplate template;    public void setHeader(String header){        this.header = header;    }    @Override    public void onOpenDocument(PdfWriter writer, Document document) {        template = writer.getDirectContent().createTemplate(30,16);    }    @Override    public void onEndPage(PdfWriter writer, Document document) {        BaseFont baseFont = null;        try {            baseFont = BaseFont.createFont("simhei.ttf",BaseFont.IDENTITY_H,BaseFont.EMBEDDED);        } catch (DocumentException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }        Font font = new Font(baseFont,12);        Rectangle rect = writer.getBoxSize("art");        //添加页眉        switch(writer.getPageNumber() % 2) {            case 0:                ColumnText.showTextAligned(writer.getDirectContent(),                        Element.ALIGN_LEFT, new Phrase("偶数页页眉",font),                        rect.getLeft(230), rect.getTop(), 0);                break;            case 1:                ColumnText.showTextAligned(writer.getDirectContent(),                        Element.ALIGN_LEFT, new Phrase("奇数页页眉",font),                        rect.getLeft(230), rect.getTop(), 0);                break;        }        //添加页码        try {            PdfPTable table = new PdfPTable(3);            //设置表格的宽度有两种方法，分别如下            table.setTotalWidth(new float[]{80,12,40});            //将宽度锁定            table.setLockedWidth(true);            table.getDefaultCell().setFixedHeight(12);            table.getDefaultCell().setBorder(Rectangle.NO_BORDER);            PdfPCell cell = new PdfPCell( new Paragraph("第 "+writer.getPageNumber()+" 页/共 ",font));            cell.setHorizontalAlignment(Element.ALIGN_RIGHT);            cell.setBorder(Rectangle.NO_BORDER);            table.addCell(cell);            PdfPCell cell1 = new PdfPCell(Image.getInstance(template));            cell.setHorizontalAlignment(Element.ALIGN_CENTER);            cell1.setBorder(Rectangle.NO_BORDER);            table.addCell(cell1);            PdfPCell cell2 = new PdfPCell(new Paragraph("页",font));            cell2.setBorder(Rectangle.NO_BORDER);            table.addCell(cell2);            table.writeSelectedRows(0,-1,235,50,writer.getDirectContent());        } catch (Exception e) {            e.printStackTrace();        }    }    @Override    public void onCloseDocument(PdfWriter writer, Document document) {        ColumnText.showTextAligned(template,Element.PARAGRAPH,new Phrase(String.valueOf(writer.getPageNumber()-1)),2,2,0);    }}
