使用pdf文本域模板生成对应的pdf
第一步:
下载jar包
<!-- itext的pdf的依赖--> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itextpdf</artifactId> <version>5.5.10</version> </dependency> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itext-pdfa</artifactId> <version>5.5.10</version> </dependency> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itext-xtra</artifactId> <version>5.5.10</version> </dependency> <dependency> <groupId>com.itextpdf.tool</groupId> <artifactId>xmlworker</artifactId> <version>5.5.10</version> </dependency> <!--itext的语言包--> <dependency> <groupId>com.itextpdf</groupId> <artifactId>itext-asian</artifactId> <version>5.2.0</version> </dependency>
第二步,写工具类
public static void fillPdf(String filePath, Map<String, String> params, String outPath) { try { PdfReader reader = new PdfReader(filePath); ByteArrayOutputStream bos = new ByteArrayOutputStream(); PdfStamper ps = new PdfStamper(reader, bos); AcroFields s = ps.getAcroFields(); // 给表单添加中文字体 这里采用系统字体。不设置的话,中文可能无法显示,这里全是英文,所以不用改成中文适应 BaseFont bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",BaseFont.NOT_EMBEDDED); s.addSubstitutionFont(bf); // 遍历data 给pdf表单表格赋值 for (String key : params.keySet()) { s.setField(key,params.get(key)); } ps.setFormFlattening(true); ps.close(); FileOutputStream fos = new FileOutputStream(outPath); fos.write(bos.toByteArray()); } catch (Exception e) { e.printStackTrace(); } }
第三步:使用
Map root = new HashMap(); root.put("realName", paper.get("realName")); root.put("sn", paper.get("sn")); root.put("title", paper.get("title")); root.put("acceptResult", paper.get("acceptResult")); String path = PathUtil.getClasspath() + "yqh"; File file = new File(path); if (!file.exists()) { file.mkdirs(); } ItextPDFUtil.fillPdf(PathUtil.getClassResources() + "pdf/paperCnInvatation.pdf", root, PathUtil.getClasspath() + "yqh/" + id + ".pdf"); try { FileUtil.fileDownload(response, PathUtil.getClasspath() + "yqh/" + id + ".pdf", "稿件邀请函.pdf"); } catch (Exception e) { e.printStackTrace(); }
