我在我的项目中使用itextpdf生成PDF文件。目前我正面临页脚的问题，而文本并没有包装仅部分文本显示在页脚中。请注意，我正在使用“ itextpdf-5.5.6.jar”作为我的库。找到我尝试过的以下代码
class HeaderAndFooterPdfPageEventHelper extends PdfPageEventHelper {
public void onEndPage(PdfWriter pdfWriter, Document document) {
String leftfooter = "This message contains information that may be privileged or confidential and is the property of XXX. It is intended only for the person to whom it is addressed.

System.out.println("onEndPage() method > Writing footer in file");
Rectangle rect = pdfWriter.getBoxSize("rectangle");
// BOTTOM LEFT
ColumnText.showTextAligned(pdfWriter.getDirectContent(),
Element.ALIGN_CENTER, new Phrase(leftfooter),
rect.getLeft()+0, rect.getBottom(), 0);
}
}
public class HowToSet_HeaderFooter_InPdfUsingItextExample extends
PdfPageEventHelper {
public static void main(String[] args) throws DocumentException, IOException {
String pdfFilePath = "E:/Set Header and Footer in Pdf Using Itext Example.pdf";
OutputStream fos = new FileOutputStream(new File(pdfFilePath));
Document document = new Document();
PdfWriter pdfWriter = PdfWriter.getInstance(document, fos);
Rectangle rectangle = new Rectangle(1000, 30, 500, 1000);
pdfWriter.setBoxSize("rectangle", rectangle);
HeaderAndFooterPdfPageEventHelper headerAndFooter =
new HeaderAndFooterPdfPageEventHelper();
pdfWriter.setPageEvent(headerAndFooter);
document.open();
document.add(new Paragraph("This is Header and Footer in Pdf Using Itext Example"));
document.close();
fos.close();
System.out.println("PDF created in >> " + pdfFilePath);
}
}
