准备工作

支付宝沙箱api

支付宝开放平台 (alipay.com)

支付参数

内网穿透 natapp.cn

natapp.cn官网

启动和配置

springboot整合—极简实现版

1.导包+配置文件

<!--        支付宝相关--><dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>4.34.0.ALL</version></dependency>

server:port: 9090# 日志需要配置一下 @Slf4j
logging:level:com.tianju.alipay: debug

2.controller层代码

订单ID，需要唯一；价格；物品名称（支付主题）

http://localhost:9090/api/ali/pay?orderId=202307302321&price=12.56&subject=iPhone

用户名：[e-mail]

密码：111111

}

3.进行支付流程

支付密码输入

支付成功

4.支付成功回调

设置异步回调

启动内网穿透

设置地址

异步回调流程解析

支付宝支付成功跳转

跳转成功

依赖注入的改进

1.整体结构

2.pom.xml文件依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.tianju.alipay</groupId><artifactId>springboot-alipay</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.5.4</version><relativePath/> <!-- lookup parent from repository --></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--json工具--><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>2.0.12</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><!--        支付宝相关--><dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>4.34.0.ALL</version></dependency></dependencies>
</project>

3.配置文件

applicaiton.yml

server:port: 9090# 日志需要配置一下 @Slf4j
logging:level:com.tianju.alipay: debug

alipay.properties

ali.privateKey = 
ali.alipayPublicKey = 
ali.appId = 9021000123613164
ali.serverUrl = https://openapi-sandbox.dl.alipaydev.com/gateway.doali.returnUrl = http://localhost:9090/aliPayReturn.html
ali.notifyUrl = http://uw7ayu.natappfree.cc/api/ali/notify

4.配置类，依赖注入

package com.tianju.alipay.config;import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;
import lombok.Getter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;@Configuration
@PropertySource("classpath:config/alipay.properties")
@Getter
public class AlipayConfig {@Value("${ali.serverUrl}")private String serverUrl;@Value("${ali.appId}")private String appId;@Value("${ali.alipayPublicKey}")private String alipayPublicKey;@Value("${ali.privateKey}")private String privateKey;@Beanpublic AlipayClient alipayClient() throws AlipayApiException {// 2.把需要配置的参数set进AlipayConfig类中com.alipay.api.AlipayConfig alipayConfig = new com.alipay.api.AlipayConfig();alipayConfig.setServerUrl(serverUrl);alipayConfig.setAppId(appId);alipayConfig.setPrivateKey(privateKey);alipayConfig.setFormat("json");alipayConfig.setAlipayPublicKey(alipayPublicKey);alipayConfig.setCharset("UTF8");alipayConfig.setSignType("RSA2");return new DefaultAlipayClient(alipayConfig);}
}

5.支付商品id，价格，名称

package com.tianju.alipay.entity;import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;@Data
@NoArgsConstructor
@AllArgsConstructor
public class Alipay {private String orderId; // 商家自定义的订单编号，唯一private String price; // 商品价格private String subject; // 支付主题
}

6.controller层进行支付和回调

7.主启动类

package com.tianju.alipay;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class AliPayApp {public static void main(String[] args) {SpringApplication.run(AliPayApp.class, args);}
}
