SpringMVC+Mybatis二維碼實現多平臺付款(附源碼)
今天,這篇文章就帶你們簡單實現多平臺支付!
整體思路:
實現微信支付寶等支付平臺合多為一的二維碼支付,並且實現有效時間內支付有效,本人采用的框架是spring springmvc mybatis框架,maven管理。其實如果支付,不需要mybatis也能實現,代碼和本人見解還需大神指教。
基本流程和思路:
- 用戶點擊支付
- 出現一次支付密碼,並且帶有時間限制
- 掃描二維碼跳轉後臺
- 後臺判斷是微信支付還是支付寶支付
1.整體架構:
2.配置編譯的文件目錄
3.pom.xml
其中qrcode.qrcode、qrcode.swetake是從本地編譯到maven庫中,因為網絡maven中沒有。
<?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> <!-- 日志處理 --> <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> <!-- 連接池 --> <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相關 --> <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>
4.二維碼相關屬性(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); } }
5.二維碼生成代碼
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 { /** * 生成二維碼(QRCode)圖片 * @param content 二維碼內容 * @param imgPath 存放二維位置 */ 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); // 設定圖像顏色> BLACK gs.setColor(Color.BLACK); // 設置偏移量 不設置可能導致解析出錯 int pixoff = 2; // 輸出內容> 二維碼 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()); // 生成二維碼QRCode圖片 ImageIO.write(bufImg, "png", imgFile); } catch (Exception e) { e.printStackTrace(); } } /** * 解碼二維碼 * @param imgPath * @return String */ public static String decoderQRCode(String imgPath) { // QRCode 二維碼圖片的文件 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) { //生成二維碼 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"); //解讀二維碼 String decoderContent =decoderQRCode(imgPath); System.out.println("解析結果如下:"); System.out.println(decoderContent); System.out.println("========decoder success!!!"); } }
6.Controller相關代碼
(jsp頁面要通過流的形式放在頁面上,不然二維碼顯示不出來。)
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); /** * 跳轉到二維碼頁面 * @param request * @return */ @RequestMapping("/toShowQRCode.do") public String showQRCode(HttpServletRequest request){ log.info("跳轉到二維碼頁面..."); return "qr"; } /** * 通過流的形式實現在jsp上面顯示二維碼 * @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();//調用無參構造方法 bc.initParam(bc);//對參數進行初始化 QRCode.encoderQRCode(bc);//生成二維碼 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); // 讀數據 is.close(); response.setContentType("image/*"); // 設置返回的文件類型 OutputStream toClient = response.getOutputStream(); // 得到向客戶端輸出二進制數據的對象 toClient.write(data); // 輸出數據 toClient.close(); } } /** * 預支付接口 * @param timeout * @param orderNo * @return */ @RequestMapping("/toPay.do") public String toPay(@RequestParam("timeout") String timeout,@RequestParam("orderNo")String orderNo){ log.info("開始進行支付"); if(StringUtils.isNullOrEmpty(orderNo)||StringUtils.isNullOrEmpty(timeout)){ log.info("訂單號或者時間超時為空"); return "faile"; } Calendar ca = Calendar.getInstance(); String afterTime = new SimpleDateFormat("yyyyMMddHHmmssSS").format(ca.getTime()); if(!afterTime.equals(timeout)){ log.info(afterTime+"---->"+timeout); log.info("二維碼已失效,請重新支付"); return "faile"; } /** * ..... 這段可以根據二維碼參數不一樣,去相關支付平臺進行支付, * 具體代碼可以根據支付平臺的api文檔進行支付操作 */ log.info("支付成功"); return "success"; } }
7.二維碼相關參數初始化
(我目前二維碼存放在本地,你們可以把二維碼放在程序目錄下)。
package com.nbt.util; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; public class BuildQRCode { /** * 二維碼存放地址 */ private String imgPath ; /** * 二維碼內容 */ private String content ; /** * 無參構造方法 */ public BuildQRCode() { } /** * 有參構造方法 * @param imgPath * @param content */ public BuildQRCode(String imgPath, String content) { super(); this.imgPath = imgPath; this.content = content; } public void initParam(BuildQRCode bqrc){ // 生成臨時訂單號和有效時間 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;//生成訂單號 //生成有效時間五分鐘 ca.add(Calendar.MINUTE,5); System.out.println(sdf.format(ca.getTime())); String timeout = sdf.format(ca.getTime()); //對參數進行初始化 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);//設置參數 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; } }
