java实现微信支付宝等多个支付平台合一的二维码支付(maven+spring springmvc mybatis框架)...

发布时间:2024/5/15 c/c++ 22 豆豆
如意编程网 收集整理的这篇文章主要介绍了 java实现微信支付宝等多个支付平台合一的二维码支付(maven+spring springmvc mybatis框架)... 小编觉得挺不错的,现在分享给大家,帮大家做个参考.
首先申明,本人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。 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。

  • <?xml version="1.0"?> <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><modelVersion>4.0.0</modelVersion><parent><groupId>fanghuai</groupId><artifactId>nbt</artifactId><version>0.0.1-SNAPSHOT</version></parent><groupId>com.nbt.qrcoder</groupId><artifactId>nbt-qrcode</artifactId><version>0.0.1-SNAPSHOT</version><packaging>war</packaging><name>nbt-qrcode Maven Webapp</name><url>http://maven.apache.org</url><properties><spring.version>4.1.3.RELEASE</spring.version><mybatis.version>3.2.8</mybatis.version><mybatis.spring.version>1.2.2</mybatis.spring.version><mybatis.paginator.version>1.2.15</mybatis.paginator.version><mysql.version>5.1.32</mysql.version><slf4j.version>1.6.4</slf4j.version><jackson.version>2.4.2</jackson.version><druid.version>1.0.9</druid.version><jstl.version>1.2</jstl.version><servlet-api.version>2.5</servlet-api.version><jsp-api.version>2.0</jsp-api.version><commons-lang3.version>3.3.2</commons-lang3.version><commons-io.version>1.3.2</commons-io.version><commons-net.version>3.3</commons-net.version><pagehelper.version>4.0.0</pagehelper.version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency><!-- qrcode --><dependency><groupId>qrcode.qrcode</groupId><artifactId>qrcode</artifactId><version>1.0</version></dependency><dependency><groupId>qrcode.swetake</groupId><artifactId>swetake</artifactId><version>1.0</version></dependency><!-- 日志处理 --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>${slf4j.version}</version></dependency><!-- Mybatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>${mybatis.version}</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>${mybatis.spring.version}</version></dependency><dependency><groupId>com.github.miemiedev</groupId><artifactId>mybatis-paginator</artifactId><version>${mybatis.paginator.version}</version></dependency><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper</artifactId><version>${pagehelper.version}</version></dependency><!-- MySql --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><!-- 连接池 --><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>${druid.version}</version></dependency><!-- Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-aspects</artifactId><version>${spring.version}</version></dependency><!-- JSP相关 --><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>${jstl.version}</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>${servlet-api.version}</version><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jsp-api</artifactId><version>${jsp-api.version}</version><scope>provided</scope></dependency></dependencies><build><finalName>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 {/*** 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;}}
