java 利用pdf模板 生成 pdf文件

pdf 模板



直接点 代码如下
@ResponseBody
@RequestMapping("/getPdf")
public Object getPdf(HttpServletResponse response) throws UnsupportedEncodingException {
// 指定解析器
System.setProperty("javax.xml.parsers.DocumentBuilderFactory",
"com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
//String path = request.getSession().getServletContext().getRealPath("/upload/");
String filename="myself.pdf";
String path="G:/pdf/";
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "attachment;fileName="
+ URLEncoder.encode(filename, "UTF-8"));
OutputStream os = null;
PdfStamper ps = null;
PdfReader reader = null;
try {
os = response.getOutputStream();
// 2 读入pdf表单
reader = new PdfReader(path+ "/"+filename);
// 3 根据表单生成一个新的pdf
ps = new PdfStamper(reader, os);
// 4 获取pdf表单
AcroFields form = ps.getAcroFields();
// 5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
BaseFont bf = BaseFont.createFont("C:/WINDOWS/Fonts/SIMSUN.TTC,1",
BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
form.addSubstitutionFont(bf);
// 6查询数据================================================
Map<String, Object> data = new HashMap<String, Object>();
data.put("name", "郭华");
data.put("like", "大美女");
// 7遍历data 给pdf表单表格赋值
for (String key : data.keySet()) {
form.setField(key,data.get(key).toString());
}
ps.setFormFlattening(true);
//-----------------------------pdf 添加图片----------------------------------
// 通过域名获取所在页和坐标，左下角为起点
System.out.println("pdf 添加图片");
String imgpath="G:/jpg/9.jpg";
int pageNo = form.getFieldPositions("img").get(0).page;
Rectangle signRect = form.getFieldPositions("img").get(0).position;
float x = signRect.getLeft();
float y = signRect.getBottom();
// 读图片
Image image = Image.getInstance(imgpath);
// 获取操作的页面
PdfContentByte under = ps.getOverContent(pageNo);
// 根据域的大小缩放图片
image.scaleToFit(signRect.getWidth(), signRect.getHeight());
// 添加图片
image.setAbsolutePosition(x, y);
under.addImage(image);
//-------------------------------------------------------------
System.out.println("===============PDF导出成功=============");
} catch (Exception e) {
System.out.println("===============PDF导出失败=============");
e.printStackTrace();
} finally {
try {
ps.close();
reader.close();
os.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return 1;
}页面路径





打开效果如下
