SpringMVC+Mybatis二维码如何实现多平台付款

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。

inalName>nbt-qrcode</finalName>    </build></project>

4.二维码相关属性（Model）

 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;    }}
