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

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.do
ali.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;
@Bean
public 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);
}
}
总结
1.springboot整合支付宝沙箱支付；
2.准备工作：沙箱api，内网穿透；
3.极简实现理解支付，异步回调等；
4.按照spring依赖注入的思想改造基础demo；
