一、导出pdf工具类:
package pdf; import java.io.ByteArrayOutputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Iterator; import java.util.Map; import com.itextpdf.text.DocumentException; import com.itextpdf.text.pdf.AcroFields; import com.itextpdf.text.pdf.BaseFont; import com.itextpdf.text.pdf.PdfReader; import com.itextpdf.text.pdf.PdfStamper; /** * 导出pdf工具类<br> * 根据给定的pdf模板,导出pdf文件,并根据给定内容替换pdf中的输入域 * @author wangtl * */ public class ExportPdfUtil { /** * * 导出pdf工具类 <br> * 导出pdf工具类 * * @param outpath 输出路径 * @param fontPath 字体路径 * @param templateName pdf模板文件路径名 * @param content 需要填充内容 * @return */ public static String exportpdf(String outpath, String templateName, String fontPath, Map<String, String> content) { // 得到当前时间 Date now = new Date(); SimpleDateFormat dataformat = new SimpleDateFormat("yyyy-MM-dd-hh-mm-ss"); String t = dataformat.format(now); // 得到一个随机数 String ran = Math.random() + ""; // 以当前时间加上一个随机数获取下载的文件以保证不重名 String filename = t + "-" + ran; String savepath = outpath + File.separator + filename + ".pdf"; PdfReader reader = null; ByteArrayOutputStream bos = null; PdfStamper ps = null; FileOutputStream fos = null; try { // 创建字体 BaseFont chineseSong = BaseFont.createFont(fontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED); // 读取pdf reader = new PdfReader(templateName); bos = new ByteArrayOutputStream(); ps = new PdfStamper(reader, bos); AcroFields s = ps.getAcroFields(); // 添加所创建的字体 s.addSubstitutionFont(chineseSong); //找到pdf中输入域并替换为内容 Iterator<String> it = s.getFields().keySet().iterator(); while(it.hasNext()){ String name = (String) it.next(); s.setField("" + name.trim(), content.get(name.trim())); } //这两步必须有,否则pdf生成失败 ps.setFormFlattening(true); ps.close(); //输出pdf fos = new FileOutputStream(savepath); fos.write(bos.toByteArray()); } catch (FileNotFoundException e) { System.out.println("FileNotFoundException"); e.printStackTrace(); } catch (Exception e) { System.out.println("Exception"); e.printStackTrace(); } finally { if (null != reader) { reader.close(); } try { if (null != bos) { bos.close(); } } catch (IOException e) { System.out.println("failed to close ByteArrayOutputStream "); } try { if (null != ps) { ps.close(); } } catch (DocumentException e) { System.out.println("failed to close PdfStamper "); } catch (IOException e) { System.out.println("failed to close PdfStamper "); } try { if (null != fos) { fos.close(); } } catch (IOException e) { System.out.println("failed to close FileOutputStream "); } } return filename; } }
二、测试类:
package test; import java.util.HashMap; import java.util.Map; import pdf.ExportPdfUtil; public class TestPdf { public static void main(String[] args) { Map<String,String> content=new HashMap<String,String>(); content.put("name", "你好");//根据模板定义的输入域的名字(如:name),填充值 ExportPdfUtil.exportpdf("C:\\", "C:\\template.pdf", "c://windows//fonts//simsun.ttc,1", content); } }
