导出效果如下
代码
1、常用的几个方法放到了一个工具类中
import com.itextpdf.text.Element;import com.itextpdf.text.Font;import com.itextpdf.text.Paragraph;import com.itextpdf.text.pdf.PdfPCell;/*** @Description: pdf工具类* @author: kylin* @create: -01-10 16:22**/public class PDFUtil {/*** 获取指定内容与字体的单元格* @param string* @param font* @return*/public static PdfPCell getPDFCell(String string, Font font){//创建单元格对象，将内容与字体放入段落中作为单元格内容PdfPCell cell=new PdfPCell(new Paragraph(string,font));cell.setHorizontalAlignment(Element.ALIGN_CENTER);cell.setVerticalAlignment(Element.ALIGN_MIDDLE);//设置最小单元格高度cell.setMinimumHeight(25);return cell;}/*** 合并行的静态函数* @param str* @param font* @param i* @return*/public static PdfPCell mergeRow(String str,Font font,int i) {//创建单元格对象，将内容及字体传入PdfPCell cell=new PdfPCell(new Paragraph(str,font));//设置单元格内容居中cell.setHorizontalAlignment(Element.ALIGN_CENTER);cell.setVerticalAlignment(Element.ALIGN_MIDDLE);//将该单元格所在列包括该单元格在内的i行单元格合并为一个单元格cell.setRowspan(i);return cell;}/*** 合并列的静态函数* @param str* @param font* @param i* @return*/public static PdfPCell mergeCol(String str,Font font,int i) {PdfPCell cell=new PdfPCell(new Paragraph(str,font));cell.setMinimumHeight(25);cell.setHorizontalAlignment(Element.ALIGN_CENTER);cell.setVerticalAlignment(Element.ALIGN_MIDDLE);//将该单元格所在行包括该单元格在内的i列单元格合并为一个单元格cell.setColspan(i);return cell;}}
2、为每一页都加上背景图
import com.itextpdf.text.BadElementException;import com.itextpdf.text.Document;import com.itextpdf.text.DocumentException;import com.itextpdf.text.Image;import com.itextpdf.text.pdf.PdfPageEventHelper;import com.itextpdf.text.pdf.PdfWriter;import java.io.IOException;/*** @Description: 为每一页pdf都生成背景图片* @author: kylin* @create: -01-08 18:00**/public class BackGroundImage extends PdfPageEventHelper {private String picPath = "";public String getPicPath() {return picPath;}public void setPicPath(String picPath) {this.picPath = picPath;}public BackGroundImage(){}public BackGroundImage(String path){this.picPath = path;}@Overridepublic void onStartPage(PdfWriter pdfWriter, Document document) {try {Image image = Image.getInstance(picPath);image.setAlignment(image.UNDERLYING);image.setAbsolutePosition(0,0);image.scaleAbsolute(595,842);document.add(image);} catch (BadElementException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (DocumentException e) {e.printStackTrace();}super.onStartPage(pdfWriter, document);}}
3、生成pdf（图片那块由于我是从数据库取出的byte[]，所以处理的有点繁琐，可以按自己的方式简化）

4、controller里面调用
/*** 导出数据 生成pdf* @param recordIds* @param isGreen* @param res*/@RequiresPermissions("sys:passRecord:export")@RequestMapping("/export/{recordIds}/{isGreen}")public void exportData(@PathVariable Long[] recordIds, @PathVariable int isGreen ,HttpServletResponse res) {List<SysPassRecordEntity> list = queryListByIds(recordIds,isGreen);try {OutputStream os = res.getOutputStream();res.setCharacterEncoding("utf-8");res.setHeader("content-type", "application/octet-stream");String date = DateUtils.format(new Date(),DateUtils.DATE_PATTERN);if(isGreen == 1){String fileName = URLEncoder.encode("绿通车辆资料" + date + ".pdf","UTF-8");res.setHeader("Content-Disposition", "attachment;filename=" + fileName);GeneratePDF.createPDF1(os,list);}if(isGreen == 0){String fileName = URLEncoder.encode("假冒绿通车辆资料" + date + ".pdf","UTF-8");res.setHeader("Content-Disposition", "attachment;filename=" + fileName);GeneratePDF.createPDF0(os,list);}os.flush();os.close();} catch (IOException e) {e.printStackTrace();}}
