前言：在商業(yè)開發(fā)中，支付業(yè)務(wù)是必不可少的一個環(huán)節(jié)。如今支付平臺常用微信支付、支付寶支付。相較而言，支付寶支付對接起來比較簡單，所以本文以支付寶支付為例。

支付寶提供的沙箱環(huán)境，入門門檻非常低，不需要商家認證那一套，這一點對開發(fā)者是非常友好的，可以直接在本地運行測試，跟最終的產(chǎn)品上線效果是一樣的，好了，廢話不說，進入正題。

一、開發(fā)流程

二、前景準備

登錄支付寶開放平臺：https://open.alipay.com/

企業(yè)支付寶注冊（非必備）：https://memberprod.alipay.com/account/reg/index.htm

支付寶支付API：https://opendocs.alipay.com/apis

密鑰生成地址：https://miniu.alipay.com/keytool/create

請求參數(shù)API：https://opendocs.alipay.com/open/02ekfg?scene=19

01、進入沙箱環(huán)境

02、獲取參數(shù)

• APPID
• 商家私鑰
• 商家公鑰
• 支付寶公鑰
• 支付寶回調(diào)地址
• 網(wǎng)關(guān)地址
• 加密算法簽名RSA2

密鑰生成地址：https://miniu.alipay.com/keytool/create

注意： 線上開發(fā)獲取支付寶公鑰的方式為：使用應(yīng)用公鑰去換取支付寶公鑰！！！

03、體驗測試賬戶

因為環(huán)境為沙箱測試環(huán)境，它提供商戶號跟買家號，但是該賬戶只能在支付寶提供的測試APK上使用。

三、PC網(wǎng)頁支付實現(xiàn)

01、創(chuàng)建springboot工程

自行創(chuàng)建

02、導入依賴

<!--freemarker模板引擎--> <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-freemarker</artifactId> </dependency> <!--web依賴--> <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId> </dependency> <!--lombok--> <dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional> </dependency> <!--test測試類--> <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope> </dependency> <!--阿里云支付SDK--> <dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>4.10.192.ALL</version> </dependency> <!--二維碼生成--> <dependency><groupId>com.google.zxing</groupId><artifactId>core</artifactId><version>3.4.1</version> </dependency> <!--解析二維碼--> <dependency><groupId>com.google.zxing</groupId><artifactId>javase</artifactId><version>3.4.1</version> </dependency> <!--加密依賴--> <dependency><groupId>commons-codec</groupId><artifactId>commons-codec</artifactId><version>1.15</version> </dependency> <!--http請求--> <dependency><groupId>commons-httpclient</groupId><artifactId>commons-httpclient</artifactId><version>3.1</version><exclusions><exclusion><artifactId>commons-logging</artifactId><groupId>commons-logging</groupId></exclusion></exclusions> </dependency> <!--配置文件加密處理--> <dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>2.1.0</version> </dependency>

03、配置yml

server:port: 8081spring:freemarker:suffix: .htmlcache: false## 支付寶支付參數(shù)配置 alipay:app_id: # APPIDmerchant_private_key: #支付寶商戶私鑰alipay_public_key: #支付寶公鑰notify_url: #服務(wù)器異步通知頁面路徑 需http://格式的完整路徑，不能加?id=123這類自定義參數(shù)，必須外網(wǎng)可以正常訪問return_url: #頁面跳轉(zhuǎn)同步通知頁面路徑 需http://格式的完整路徑，不能加?id=123這類自定義參數(shù)，必須外網(wǎng)可以正常訪問（如果是二維碼掃碼可以不配置）sing_type: RSA2charset: utf-8gatewayurl: https://openapi.alipaydev.com/gateway.do # https://openapi.alipay.com/gateway.do 線上地址# 保存支付日志的地址log_path: D:/tmp/

04、定義支付配置類 AlipayConfig

package com.qd.config; import org.springframework.beans.factory.annotation.Value; import org.springframework.stereotype.Component; import java.io.FileWriter; import java.io.IOException; /*** 支付寶支付配置類** @Blog: https://www.cnblogs.com/qd666* @Author: qiandu* @Date: 2021/11/27 11:22*/ @Component public class AlipayConfig {// 應(yīng)用IDpublic static String app_id;// 商戶私鑰public static String merchant_private_key;// 支付寶公鑰public static String alipay_public_key;// 服務(wù)器異步通知頁面路徑 需http://格式的完整路徑，不能加?id=123這類自定義參數(shù)，必須外網(wǎng)可以正常訪問public static String notify_url;// 頁面跳轉(zhuǎn)同步通知頁面路徑 需http://格式的完整路徑，不能加?id=123這類自定義參數(shù)，必須外網(wǎng)可以正常訪問public static String return_url;// 簽名方式public static String sign_type;// 字符編碼格式public static String charset;// 支付寶網(wǎng)關(guān)public static String gatewayUrl;// 日志地址public static String log_path;/*** 寫日志，方便測試（看網(wǎng)站需求，也可以改成把記錄存入數(shù)據(jù)庫）*/public static void logResult(String sWord) {FileWriter writer = null;try {writer = new FileWriter(log_path + "alipay_log_" + System.currentTimeMillis() + ".txt");writer.write(sWord);} catch (Exception e) {e.printStackTrace();} finally {if (writer != null) {try {writer.close();} catch (IOException e) {e.printStackTrace();}}}}/*** 配置文件靜態(tài)屬性注入*/@Value("${alipay.app_id}")public void setApp_id(String app_id) {this.app_id = app_id;}@Value("${alipay.merchant_private_key}")public void setMerchant_private_key(String merchant_private_key) {this.merchant_private_key = merchant_private_key;}@Value("${alipay.alipay_public_key}")public void setAlipay_public_key(String alipay_public_key) {this.alipay_public_key = alipay_public_key;}@Value("${alipay.notify_url}")public void setNotify_url(String notify_url) {this.notify_url = notify_url;}@Value("${alipay.return_url}")public void setReturn_url(String return_url) {this.return_url = return_url;}@Value("${alipay.sing_type}")public void setSign_type(String sign_type) {this.sign_type = sign_type;}@Value("${alipay.charset}")public void setCharset(String charset) { this.charset = charset;}@Value("${alipay.gatewayurl}")public void setGatewayUrl(String gatewayUrl) {this.gatewayUrl = gatewayUrl;}@Value("${alipay.log_path}")public void setLog_path(String log_path) {this.log_path = log_path;} }

notify_url：異步通知，當你支付成功時，支付寶回調(diào)你本地啟動項目的接口，必須是外網(wǎng)可以訪問的，否則支付寶請求不到，但是又得是你本地的方法「不討論線上測試」可以使用工具實現(xiàn)內(nèi)網(wǎng)穿透

05、支付寶支付工具類

package com.qd.controller;import com.alipay.api.AlipayApiException; import com.alipay.api.AlipayClient; import com.alipay.api.DefaultAlipayClient; import com.alipay.api.internal.util.AlipaySignature; import com.qd.config.AlipayConfig; import lombok.extern.slf4j.Slf4j; import javax.servlet.http.HttpServletRequest; import java.io.UnsupportedEncodingException; import java.util.HashMap; import java.util.Iterator; import java.util.Map;/*** 支付寶支付工具類** @Blog: https://www.cnblogs.com/qd666* @Author: qiandu* @Date: 2021/11/27 11:25*/ @Slf4j public class AliPayUtil {/*** 初始化AlipayClient*/public static AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig.gatewayUrl, AlipayConfig.app_id, AlipayConfig.merchant_private_key, "json", AlipayConfig.charset, AlipayConfig.alipay_public_key, AlipayConfig.sign_type);/*** 轉(zhuǎn)碼*/public static String getByte(String param) {try {return new String(param.getBytes("ISO-8859-1"), "UTF-8");} catch (UnsupportedEncodingException e) {e.printStackTrace();return null;}}/*** 校驗簽名*/public static boolean rsaCheckV1(HttpServletRequest request) {// https://docs.open.alipay.com/54/106370// 獲取支付寶POST過來反饋信息Map<String, String> params = new HashMap<>();Map requestParams = request.getParameterMap();for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext(); ) {String name = (String) iter.next();String[] values = (String[]) requestParams.get(name);String valueStr = "";for (int i = 0; i < values.length; i++) {valueStr = (i == values.length - 1) ? valueStr + values[i]: valueStr + values[i] + ",";}params.put(name, valueStr);}try {boolean signVerified = AlipaySignature.rsaCheckV1(params, AlipayConfig.alipay_public_key, AlipayConfig.charset, AlipayConfig.sign_type);return signVerified;} catch (AlipayApiException e) {log.debug("verify sigin error, exception is:{}", e);return false;}} }

06、參數(shù)封裝成實體類

@Data @AllArgsConstructor @NoArgsConstructor public class Order implements java.io.Serializable{// 商品訂單號 必填private String out_trade_no;;// 訂單名稱 必填private String subject;// 付款金額 必填private String total_amount;// 商品描述private String description;// 超時時間private String timeout_express = "10m";// 產(chǎn)品編號 必填private String product_code = "FAST_INSTANT_TRADE_PAY"; }

07、AliController(自行拆分service)

08、運行結(jié)果

四、二維碼當面付實現(xiàn)

01、創(chuàng)建springboot項目

02、導入依賴

03、定義支付配置類 AlipayConfig

04、支付寶支付工具類

這些步驟與前面一樣，請看上

05、配置yml文件

09、訪問測試

tip:為了數(shù)據(jù)更加的安全，可以加密部分數(shù)據(jù)，加密部分本文暫未涉及

五、yml文件加密

前言：在實際的項目開發(fā)中，在我們的配置文件中會有隱私數(shù)不想以明文方式展現(xiàn)，所以要加密yml文件

01、導入依賴

<!--配置文件加密處理--> <dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>2.1.0</version> </dependency>

02、編寫測試類

@SpringBootTest public class JasypTest {// 加密測試@Testpublic void encryptTest() {StandardPBEStringEncryptor standardPBEBigDecimalEncryptor = new StandardPBEStringEncryptor();EnvironmentPBEConfig config = new EnvironmentPBEConfig();config.setPassword("fsdfs8979!~#!@#rewr"); //密鑰 不要告訴別人！！！standardPBEBigDecimalEncryptor.setConfig(config);String plainText = "hell,qiandu"; // 要加密的內(nèi)容String encryptText = standardPBEBigDecimalEncryptor.encrypt(plainText);System.out.println("加密結(jié)果---->" + encryptText);}// 解密測試@Testpublic void decTest() {StandardPBEStringEncryptor standardPBEBigDecimalEncryptor = new StandardPBEStringEncryptor();EnvironmentPBEConfig config = new EnvironmentPBEConfig();config.setPassword("fsdfs8979!~#!@#rewr"); //密鑰 不要告訴別人！！！standardPBEBigDecimalEncryptor.setConfig(config);String encryptText = "6fJIuViOKsNpxPk8ce6CAUiIftXuKb9x"; // 要解密的內(nèi)容String plainText = standardPBEBigDecimalEncryptor.decrypt(encryptText);System.out.println("解密結(jié)果---->" + plainText);} }

03、啟動類上加入注解

@SpringBootApplication @EnableEncryptableProperties //開啟加密注解 public class AlipayApplication {public static void main(String[] args) {SpringApplication.run(AlipayApplication.class, args);}}

04、在yml中配置（記得作隔離！）

## jasypt配置 jasypt:encryptor:# 密鑰password: #你的密鑰
