摘要

今天，这篇文章就带你们简单实现多平台支付！

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：

这里写图片描述

2.配置编译的文件目录

这里写图片描述

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。

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;
    }
}
