java pdf stamper

注意:本例子是从向模板定义的变量赋值,而不是从无到有的来生成pdf

直接就能用

maven依赖:

com.lowagie

itext

4.2.1

工具类:

package com.upincar.pdfdemo2.demo;

import com.itextpdf.text.pdf.AcroFields;

import com.itextpdf.text.pdf.BaseFont;

import com.itextpdf.text.pdf.PdfReader;

import com.itextpdf.text.pdf.PdfStamper;

import java.io.ByteArrayOutputStream;

import java.io.File;

import java.io.FileOutputStream;

import java.util.ArrayList;

public class PDFTemplet {

public void PDFTemplet (File file)throws Exception{

//本地模板路径

String templatePdfPath = PDFTemplet.class.getResource("/pdf/" + "/notice_template.pdf").toString();

//生产pdfreader

PdfReader reader = new PdfReader(templatePdfPath);

ByteArrayOutputStream bos=new ByteArrayOutputStream();

/* 读取*/

PdfStamper pdfStamper= new PdfStamper(reader,bos);

/*设置字体格式*/

BaseFont baseFont = BaseFont.createFont("C:/WINDOWS/Fonts/SIMSUN.TTC,1", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

ArrayList fontList=new ArrayList<>();

fontList.add(baseFont);

AcroFields s=pdfStamper.getAcroFields();

s.setSubstitutionFonts(fontList);

/*Field , 这个是自己在pdf上定义的变量名称*/

s.setField("sign_year","2019");

s.setField("sign_month","06");

s.setField("sign_day","27");

pdfStamper.setFormFlattening(true);

pdfStamper.close();

FileOutputStream fileSteam =new FileOutputStream(file);

fileSteam.write(bos.toByteArray());

fileSteam.close();

}

}

测试类

package com.upincar.pdfdemo2.demo;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;

import java.io.File;

@RestController

public class TestController{

@RequestMapping(value ="downloadJavaPdf", method = RequestMethod.GET)

public String downloadJavaPdf(HttpServletRequest request) throws Exception {

PDFTemplet pdfTT = new PDFTemplet();

File file = new File("D:/测试用.pdf");

file.createNewFile();

pdfTT.PDFTemplet(file);

return "生成成功";

}

}
