Spring Boot集成支付宝沙箱支付

1、注册支付宝开发者账户，进入开发者控制台

https://openhome.alipay.com/platform/developerIndex.htm

支付宝沙箱支付

沙箱界面：

沙箱界面

2、Spring Boot集成沙箱支付

1、导入Maven依赖

<!--支付宝沙箱支付-->
<dependency>
	<groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>4.22.110.ALL</version>
</dependency>

2、在application.yml进行配置

alipay:
  appId: 
  appPrivateKey:
  alipayPublicKey: 
  notifyUrl:

alipay配置1
alipay配置2

3、内网穿透：https://natapp.cn/ 配置免费隧道

alipay配置3

4、下载客户端并解压，配置authtoken

alipay配置4
alipay配置5

5、双击start.bat启动，启动后不要关闭

alipay配置6

6、更新application.yml的配置，如果是在本地运行，每次启动项目的时候都要启动start.bat，并且都要更改notifyUrl

alipay:
  appId: 
  appPrivateKey:
  alipayPublicKey: 
  # 这里的notifyUrl是：上面的红圈部分/alipay/notify
  notifyUrl: http://zg689r.natappfree.cc/alipay/notify

7、Java配置沙箱支付：

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;
}

import lombok.Data;

@Data
public class AliPay {
    private String traceNo;
    private double totalAmount;
    private String subject;
    private String alipayTraceNo;
}

        AlipayClient alipayClient = new DefaultAlipayClient(GATEWAY_URL, aliPayConfig.getAppId(),
                aliPayConfig.getAppPrivateKey(), FORMAT, CHARSET, aliPayConfig.getAlipayPublicKey(), SIGN_TYPE);

        // 2. 创建 Request并设置Request参数
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();  // 发送请求的 Request类

        bizContent.set("product_code", "FAST_INSTANT_TRADE_PAY");  // 固定配置
        request.setBizContent(bizContent.toString());

        // 执行请求，拿到响应的结果，返回给浏览器
        String form = "";
        try {

        }

            Map<String, String> params = new HashMap<>();
