Spring Boot接支付宝第三方支付(沙箱)

第三方支付笔记：java接支付宝第三方支付

第一步：沙箱登录注册

支付宝官网的教程：/isv/009v0y

沙箱登录注册地址：（因为是支付宝需支付宝扫码）

注册登录后，会进入控制台，点击研发服务。

进入看到沙箱，会看到自己的APPID等基本信息，java接入时需要。

第二步生成公钥私钥

支付宝公私钥的文档地址：/open/291/105971

因为比较勤奋，我点击第一个，无需下载

生成后将公钥放到的控制台，秘钥处（公钥，私钥都要保存）

连接第三方的基本信息搞定，接下来可以springboot进行测试

第三步springboot接入

网上代码测试：/xifengxiaoma/p/10107635.html

主要依赖：

<dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>3.1.0</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.48</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency>

alipay.properties文件（需生成的公钥私钥，ID等）：

支付宝接入环境配置文档：/open/200/105311

# 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号appId:000117636117# 商户私钥，您的PKCS8格式RSA2私钥privateKey: （自己生成的私钥）# 支付宝公钥,查看地址：/platform/keyManage.htm 对应APPID下的支付宝公钥。publicKey: （自己生成的公钥）# 服务器异步通知页面路径需http://格式的完整路径，不能加?id=123这类自定义参数#notifyUrl: http://外网ip:端口/error.html## 页面跳转同步通知页面路径需http://格式的完整路径，不能加?id=123这类自定义参数#returnUrl: http://外网ip:端口/sccess.html# 签名方式signType: RSA2# 字符编码格式charset: utf-8# 支付宝网关gatewayUrl: /gateway.do# 支付宝网关logPath: "C:\\"

model：

@Datapublic class Alipay implements Serializable {/*** 商品订单号，必填*/private String out_trade_no;/*** 商品标题*/private String subject;/*** 付款金额，必填* 根据支付宝接口协议，必须使用下划线*/private String total_amount;/*** 商品描述，可空*/private String body;/*** 超时时间参数*/private String timeout_express= "10m";/*** 产品编号*/private String product_code= "FAST_INSTANT_TRADE_PAY";}

AlipayProperties文件，主要是获取alipay.properties文件信息

@Componentpublic class AlipayProperties {public static final String APP_ID = "appId";public static final String PRIVARY_KEY = "privateKey";public static final String PUBLIC_KEY = "publicKey";public static final String NOTIFY_URL = "notifyUrl";public static final String RETURN_URL = "returnUrl";public static final String SIGN_TYPE = "signType";public static final String CHARSET = "charset";public static final String GATEWAY_URL = "gatewayUrl";public static final String LOG_PATH = "logPath";/*** 保存加载配置参数*/private static Map<String, String> propertiesMap = new HashMap<String, String>();/*** 加载属性*/public static void loadProperties() {PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();try {Resource resources = resolver.getResource("classpath:alipay.properties");PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();propertiesFactoryBean.setLocation(resources);propertiesFactoryBean.afterPropertiesSet();Properties properties = propertiesFactoryBean.getObject();for (String key:properties.stringPropertyNames()) {propertiesMap.put(key,(String) properties.get(key));}} catch (IOException e) {e.printStackTrace();}catch (Exception e) {new Exception("配置文件加载失败");}}/*** 获取配置参数值* @param key* @return*/public static String getKey(String key) {return propertiesMap.get(key);}public static String getAppId() {return propertiesMap.get(APP_ID);}public static String getPrivateKey() {return propertiesMap.get(PRIVARY_KEY);}public static String getPublicKey() {return propertiesMap.get(PUBLIC_KEY);}public static String getNotifyUrl() {return propertiesMap.get(NOTIFY_URL);}public static String getReturnUrl() {return propertiesMap.get(RETURN_URL);}public static String getSignType() {return propertiesMap.get(SIGN_TYPE);}public static String getCharset() {return propertiesMap.get(CHARSET);}public static String getGatewayUrl() {return propertiesMap.get(GATEWAY_URL);}public static String getLogPath() {return propertiesMap.get(LOG_PATH);}}

PropertiesListener文件（配置监听，每次项目运行前读取alipay.properties文件信息）

/*** @Author: Lanys* @Description:* @Date: Create in 22:08 /4/10*/@Componentpublic class PropertiesListener implements ApplicationListener<ApplicationStartedEvent> {@Overridepublic void onApplicationEvent(ApplicationStartedEvent applicationStartedEvent) {AlipayProperties.loadProperties();}}

controller：

*** 订单接口* * @author Louis* @date Dec 12, */@RestController()@RequestMapping("order")public class OrderController {@Autowiredprivate PayService payService;/*** 阿里支付* @param tradeNo* @param subject* @param amount* @param body* @return* @throws AlipayApiException*/@PostMapping(value = "alipay")public String alipay(String outTradeNo, String subject, String totalAmount, String body) throws AlipayApiException {Alipay alipayBean = new Alipay();alipayBean.setOut_trade_no(outTradeNo);alipayBean.setSubject(subject);alipayBean.setTotal_amount(totalAmount);alipayBean.setBody(body);return payService.aliPay(alipayBean);}}

service：

/*** 支付服务* @author Louis* @date Dec 12, */public interface PayService {/*** 支付宝支付接口* @param alipayBean* @return* @throws AlipayApiException*/String aliPay(Alipay alipayBean) throws AlipayApiException;}

Impl：

@Servicepublic class PayServiceImpl implements PayService {@Autowiredprivate AlipayConfig alipayConfig;@Overridepublic String aliPay(Alipay alipayBean) throws AlipayApiException {return alipayConfig.pay(alipayBean);}}

接入：

/*** @Author: Lanys* @Description:* @Date: Create in 22:31 /4/10*/@Componentpublic class AlipayConfig {/*** 支付接口* @param alipayBean* @return* @throws AlipayApiException*/public String pay(Alipay alipayBean) throws AlipayApiException {String serverUrl = AlipayProperties.getGatewayUrl();String appId = AlipayProperties.getAppId();String privateKey = AlipayProperties.getPrivateKey();String format = "json";String charset = AlipayProperties.getCharset();String alipayPublicKey = AlipayProperties.getPublicKey();String signType = AlipayProperties.getSignType();String returnUrl = AlipayProperties.getReturnUrl();String notifyUrl = AlipayProperties.getNotifyUrl();AlipayClient alipayClient = new DefaultAlipayClient(serverUrl, appId, privateKey, format, charset, alipayPublicKey, signType);AlipayTradePagePayRequest alipayOpenAppServiceApplyRequest = new AlipayTradePagePayRequest();alipayOpenAppServiceApplyRequest.setReturnUrl(returnUrl);alipayOpenAppServiceApplyRequest.setNotifyUrl(notifyUrl);alipayOpenAppServiceApplyRequest.setBizContent(JSON.toJSONString(alipayBean));String alipayTradePagePayResponse = alipayClient.pageExecute(alipayOpenAppServiceApplyRequest).getBody();return alipayTradePagePayResponse;}}

html:

<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>Title</title></head><body><H1>支付测试</H1><hr><div class="form-container"><form id="form" action="order/alipay" method="post">*商户订单 :<input type="text" name="outTradeNo" value="dzcp100010001"><br>*订单名称 :<input type="text" name="subject" value="华为手机"><br>*付款金额 :<input type="text" name="totalAmount" value="0.1" ><br>*商品描述 :<input type="text" name="body" value="华为P40手机 "><br><input type="button" value="支付宝支付" onclick="submitForm('order/alipay')"> </form></div></body>

点击支付宝支付后

问题：

![在这里插入图片描述](https://img-/0411230116832.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQ0Njk3NzU0,size_16,color_FFFFFF,t_70

如果出现上面这种情况，关闭支付宝相关的页面（建议关闭浏览器重启重新访问自己的接口就可以了）
