支付宝沙箱环境配置：

进入支付宝平台获取应用id

进行接口加签方式配置生成应用私钥和支付宝公钥

设置回调地址支付宝通过这个回调地址来通知支付结果

项目中的配置

1.pom.xml引入支付宝SDK依赖

<!--        支付宝沙箱-->
        <dependency>
            <groupId>com.alipay.sdk</groupId>
            <artifactId>alipay-sdk-java</artifactId>
            <version>4.35.79.ALL</version>
        </dependency>

2.配置在application.yaml中配置支付宝

alipay:
  appId: 9021000142649315
  appPrivateKey: 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

  notifyUrl:

alipay:

  appId: 你的appId应用id

  appPrivateKey: 你的应用私钥

  alipayPublicKey: 支付宝公钥

  notifyUrl: 你的异步通知回调地址

3.创建alipay.config配置类，初始化支付宝配置

4.创建支付接口调用支付宝SDK生成支付请求

5.设置外网域名作为回调接口，接受支付宝异步通知
