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：
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。

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 {
/**
* 生成二维码(QRCode)图片
* @param content 二维码内容
* @param imgPath 存放二维位置
*/
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();
}
}
/**
* 解码二维码
* @param imgPath
* @return String
*/
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);
/**
* 跳转到二维码页面
* @param request
* @return
*/
@RequestMapping("/toShowQRCode.do")
public String showQRCode(HttpServletRequest request){
log.info("跳转到二维码页面...");
return "qr";
}
/**
* 通过流的形式实现在jsp上面显示二维码
* @param model
* @param request
* @param response
* @throws IOException
*/
@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/*"); // 设置返回的文件类型
OutputStream toClient = response.getOutputStream(); // 得到向客户端输出二进制数据的对象
toClient.write(data); // 输出数据
toClient.close();
}
}
/**
* 预支付接口
* @param timeout
* @param orderNo
* @return
*/
@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";
}
/**
* ..... 这段可以根据二维码参数不一样，去相关支付平台进行支付，
* 具体代码可以根据支付平台的api文档进行支付操作
*/
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 {
/**
* 二维码存放地址
*/
private String imgPath ;
/**
* 二维码内容
*/
private String content ;
/**
* 无参构造方法
*/
public BuildQRCode() {
}
/**
* 有参构造方法
* @param imgPath
* @param content
*/
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;
}
}
