文件轮换后,我在页面中丢失了数据的顺序:
package com.mkyong.common.view;
import java.io.File;
import java.io.IOException;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.view.document.AbstractPdfView;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.PageSize;
import com.lowagie.text.Table;
import com.lowagie.text.pdf.PdfWriter;
import com.lowagie.text.Image;
public class PdfRevenueReportView extends AbstractPdfView{
@Override
protected void buildPdfDocument(Map model, Document document,
PdfWriter writer, HttpServletRequest request,
HttpServletResponse response) throws Exception {
Image im= Image.getInstance("D:\\tree2.png");
// setSize
im.scaleToFit(130, 150);
Map<String,String> revenueData = (Map<String,String>) model.get("revenueData");
Table table = new Table(2);
table.addCell("Month");
table.addCell("Revenue");
for (Map.Entry<String, String> entry : revenueData.entrySet()) {
table.addCell(entry.getKey());
table.addCell(entry.getValue());
}
document.setPageSize(PageSize.A4.rotate());
document.newPage();
document.add(im);
document.add(table);
}
}
给我这个:
当我改变这两行的位置时:
document.setPageSize(PageSize.A4.rotate());
document.newPage();
它返回默认位置。问题在哪里?
谢谢。

试试这个:
Document document = new Document(PageSize.A4.rotate());

通过这种方式解决:
document.setPageSize(PageSize.A4.rotate());
document.open();
document.newPage();
谢谢@Alex。

这是在(新)itext 7中旋转页面的代码:
PdfDocument pdfDoc = new PdfDocument(new PdfReader(src), new PdfWriter(dest));
for (int i = 1; i <= pdfDoc.getNumberOfPages(); i++) {
PdfPage page = pdfDoc.getPage(i);
page.setRotation(180);
}
pdfDoc.close();
