In the .NET version I just create a table with a border. I know it isn't Java but maybe the following code will help you.
在 .NET 版本中，我只是创建了一个带边框的表格。我知道它不是 Java，但也许下面的代码会对你有所帮助。
iTextSharp.text.Document document = new iTextSharp.text.Document(PageSize.LETTER, 20, 20, 20, 20);
PdfPTable table;
PdfPCell cell;
// single element w/ border
table = new PdfPTable(1);
cell = new PdfPCell(new Phrase("BOLD WORDS", FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 11, Font.BOLD)));
cell.BorderWidth = 2;
cell.Padding = 5;
cell.PaddingTop = 3;
cell.HorizontalAlignment = Element.ALIGN_CENTER;
table.AddCell(cell);
table.SetWidthPercentage(new float[1] { 598f }, PageSize.LETTER);
table.HorizontalAlignment = Element.ALIGN_CENTER;
document.Add(table);

public static void drawRectangle(PdfContentByte content, float width, float height) {
content.saveState();
PdfGState state = new PdfGState();
state.setFillOpacity(0.6f);
content.setGState(state);
content.setRGBColorFill(0xFF, 0xFF, 0xFF);
content.setLineWidth(3);
content.rectangle(0, 0, width, height);
content.fillStroke();
content.restoreState();
}
