小编给大家分享一下SpringMVC+Mybatis二维码如何实现多平台付款，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
整体思路：
实现微信支付宝等支付平台合多为一的二维码支付，并且实现有效时间内支付有效，本人采用的框架是spring springmvc mybatis框架，maven管理。其实如果支付，不需要mybatis也能实现，代码和本人见解还需大神指教。
基本流程和思路：
用户点击支付
出现一次支付密码，并且带有时间限制
扫描二维码跳转后台
后台判断是微信支付还是支付宝支付
1.整体架构：
2.配置编译的文件目录
3.pom.xml
其中qrcode.qrcode、qrcode.swetake是从本地编译到maven库中，因为网络maven中没有。

package com.nbt.util;import java.awt.image.BufferedImage;import jp.sourceforge.qrcode.data.QRCodeImage; public class J2SEImage implements QRCodeImage { BufferedImage bufImg; public J2SEImage(BufferedImage bufImg) { this.bufImg = bufImg; } public int getWidth() { return bufImg.getWidth(); } public int getHeight() { return bufImg.getHeight(); } public int getPixel(int x, int y) { return bufImg.getRGB(x, y); } }5.二维码生成代码
package com.nbt.util; import java.awt.Color;import java.awt.Graphics2D;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException; import javax.imageio.ImageIO; import jp.sourceforge.qrcode.QRCodeDecoder;import jp.sourceforge.qrcode.exception.DecodingFailedException; import com.swetake.util.Qrcode; public class QRCode { public static void encoderQRCode(BuildQRCode bc) { try { Qrcode qrcodeHandler = new Qrcode(); qrcodeHandler.setQrcodeErrorCorrect('M'); qrcodeHandler.setQrcodeEncodeMode('B'); qrcodeHandler.setQrcodeVersion(7); System.out.println(bc.getContent()); byte[] contentBytes = bc.getContent().getBytes("gb2312"); BufferedImage bufImg = new BufferedImage(140, 140, BufferedImage.TYPE_INT_RGB); Graphics2D gs = bufImg.createGraphics(); gs.setBackground(Color.WHITE); gs.clearRect(0, 0, 140, 140); // 设定图像颜色> BLACK gs.setColor(Color.BLACK); // 设置偏移量 不设置可能导致解析出错 int pixoff = 2; // 输出内容> 二维码 if (contentBytes.length > 0 && contentBytes.length < 120) { boolean[][] codeOut = qrcodeHandler.calQrcode(contentBytes); for (int i = 0; i < codeOut.length; i++) { for (int j = 0; j < codeOut.length; j++) { if (codeOut[j][i]) { gs.fillRect(j * 3 + pixoff, i * 3 + pixoff, 3, 3); } } } } else { System.err.println("QRCode content bytes length = " + contentBytes.length + " not in [ 0,120 ]. "); } gs.dispose(); bufImg.flush(); File imgFile = new File(bc.getImgPath()); // 生成二维码QRCode图片 ImageIO.write(bufImg, "png", imgFile); } catch (Exception e) { e.printStackTrace(); } } public static String decoderQRCode(String imgPath) { // QRCode 二维码图片的文件 File imageFile = new File(imgPath); BufferedImage bufImg = null; String decodedData = null; try { bufImg = ImageIO.read(imageFile); QRCodeDecoder decoder = new QRCodeDecoder(); decodedData = new String(decoder.decode(new J2SEImage(bufImg))); // try { // System.out.println(new String(decodedData.getBytes("gb2312"), // "gb2312")); // } catch (Exception e) { // // TODO: handle exception // } } catch (IOException e) { System.out.println("Error: " + e.getMessage()); e.printStackTrace(); } catch (DecodingFailedException dfe) { System.out.println("Error: " + dfe.getMessage()); dfe.printStackTrace(); } return decodedData; } public static void main(String[] args) { //生成二维码 String imgPath = "D:/test/Michael_QRCode.png"; String content = "http://www.baidu.com"; BuildQRCode bc = new BuildQRCode(imgPath,content); encoderQRCode(bc); System.out.println("encoder QRcode success"); //解读二维码 String decoderContent =decoderQRCode(imgPath); System.out.println("解析结果如下："); System.out.println(decoderContent); System.out.println("========decoder success!!!"); } }6.Controller相关代码
(jsp页面要通过流的形式放在页面上，不然二维码显示不出来。)
package com.nbt.controller; import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.io.OutputStream;import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Map; import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse; import org.apache.log4j.Logger;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam; import com.mysql.jdbc.StringUtils;import com.nbt.util.BuildQRCode;import com.nbt.util.QRCode;@Controller@RequestMapping("/qr")public class QRCodeController { private static Logger log = Logger.getLogger(QRCodeController.class); @RequestMapping("/toShowQRCode.do") public String showQRCode(HttpServletRequest request){ log.info("跳转到二维码页面..."); return "qr"; } @RequestMapping("/readImage") public void readImage(Model model, HttpServletRequest request, HttpServletResponse response) throws IOException{ BuildQRCode bc = new BuildQRCode();//调用无参构造方法 bc.initParam(bc);//对参数进行初始化 QRCode.encoderQRCode(bc);//生成二维码 String filePath = bc.getImgPath(); File filePic = new File(filePath); if(filePic.exists()){ FileInputStream is = new FileInputStream(filePic); int i = is.available(); // 得到文件大小 byte data[] = new byte[i]; is.read(data); // 读数据 is.close(); response.setContentType("image @RequestMapping("/toPay.do") public String toPay(@RequestParam("timeout") String timeout,@RequestParam("orderNo")String orderNo){ log.info("开始进行支付"); if(StringUtils.isNullOrEmpty(orderNo)||StringUtils.isNullOrEmpty(timeout)){ log.info("订单号或者时间超时为空"); return "faile"; } Calendar ca = Calendar.getInstance(); String afterTime = new SimpleDateFormat("yyyyMMddHHmmssSS").format(ca.getTime()); if(!afterTime.equals(timeout)){ log.info(afterTime+"---->"+timeout); log.info("二维码已失效，请重新支付"); return "faile"; } log.info("支付成功"); return "success"; }}7.二维码相关参数初始化
(我目前二维码存放在本地，你们可以把二维码放在程序目录下)。
package com.nbt.util; import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.Date; public class BuildQRCode { private String imgPath ; private String content ; public BuildQRCode() { } public BuildQRCode(String imgPath, String content) { super(); this.imgPath = imgPath; this.content = content; } public void initParam(BuildQRCode bqrc){ // 生成临时订单号和有效时间 Calendar ca = Calendar.getInstance(); Date date = ca.getTime(); SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmssSS"); System.out.println(sdf.format(date)); String orderNo = sdf.format(date)+(int)Math.random()*1000;//生成订单号 //生成有效时间五分钟 ca.add(Calendar.MINUTE,5); System.out.println(sdf.format(ca.getTime())); String timeout = sdf.format(ca.getTime()); //对参数进行初始化 bqrc.setImgPath( "D:/test/Michael_QRCode.png"); bqrc.setContent( "http://localhost:8080/nbt-qrcode/qr/toPay.do?orderNo="+orderNo+"&timeout="+timeout); } public static void main(String[] args) { BuildQRCode qc = new BuildQRCode(); qc.initParam(qc);//设置参数 QRCode.encoderQRCode(qc); } public String getImgPath() { return imgPath; } public void setImgPath(String imgPath) { this.imgPath = imgPath; } public String getContent() { return content; } public void setContent(String content) { this.content = content; }}以上是“SpringMVC+Mybatis二维码如何实现多平台付款”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注编程网行业资讯频道！
