# 添加yml配置

alipay:
    appId: xxx
    appPrivateKey: xxx
    alipayPublicKey: xxx
    notifyUrl: xxx

# notifyUrl配置

内网穿透

# 注册

官网：https://natapp.cn/ 需要先注册账号，实名认证。

# 隧道

进入后需要购买我的隧道，使用free即可，里面的端口填写自己需要的端口即可。 zfbsx-1

# 客户端

下载客户端 https://natapp.cn/#download 解压

# 配置start.bat

创建start.bat，内容如下 natapp.exe -authtoken= xxx 这个authToken就是natapp里面隧道的authToken zfbsx-2 里面获取网址

# notifyUrl配置

xxx/alipay/notify 注意这里的/alipay/notify是controller的接口地址，如果添加了servlet-contextPath,就需要加上这个前缀，例如我的是/api,所以正确配置是xxx/api/alipay/notify

# 编写配置类

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Data
@Component
@ConfigurationProperties(prefix = "alipay")
public class AliPayConfig {
    private String appId;
    private String appPrivateKey;
    private String alipayPublicKey;
    private String notifyUrl;
}

# 编写实体类

我的地址是，http://localhost:7529/api/alipay/pay?&subject=%E8%A5%BF%E7%93%9C&traceNo=2022123&totalAmount=12.1 zfbsx-3

支付账号可以从支付宝里面沙箱账号获取 zfbsx-4

# 界面回调

配置yml,alipay里面配置，这个地址是你的前端回调的地址

  returnUrl: xxx

实体类也要添加

    private String alipayTraceNo;

controller

        request.setNotifyUrl(aliPayConfig.getNotifyUrl());
        request.setReturnUrl(aliPayConfig.getReturnUrl());
