首先此文章是转载了青戈老师的视频讲解[ 青戈老师][Link 1]

1、导入支付宝的SDK pom文件

<dependency>
                <groupId>com.alipay.sdk</groupId>
                <artifactId>alipay-easysdk</artifactId>
                <version>2.2.1</version>
            </dependency>

2、application.yml配置 [直达链接][Link 2]

alipay:
      appId: 你自己的appID
      appPrivateKey: 自己的私钥
      alipayPublicKey: 支付宝的公钥
      notifyUrl:

3、Controller

@GetMapping("/pay")
    public CommonResult pay(AliPay aliPay) {
        System.out.println(aliPay);
        AlipayTradePagePayResponse response;
        try {
            //  发起API调用（以创建当面付收款二维码为例）
            response = Factory.Payment.Page()
                    .pay(URLEncoder.encode(aliPay.getSubject(), "UTF-8"), aliPay.getTraceNo(), aliPay.getTotalAmount(), "");
        } catch (Exception e) {
            System.err.println("调用遭遇异常，原因：" + e.getMessage());
            throw new RuntimeException(e.getMessage(), e);
        }
        System.out.println(response.body);
        return CommonResult.ok(response.body);
    }

4、实体类

private String traceNo;
    private String totalAmount;
    private String subject;
    private String alipayTraceNo;

5、aliPayConfig包

@Data
    @Component
    @ConfigurationProperties(prefix = "alipay")
    public class AplipayConfig {
    
        private String appId;
        private String appPrivateKey;
        private String alipayPublicKey;
        private String notifyUrl;
    
        @PostConstruct
        public void init() {
            // 设参（只需设置一次）
            Config options = getOptions();
            options.appId = this.appId;
            options.merchantPrivateKey = this.appPrivateKey;
            options.alipayPublicKey = this.alipayPublicKey;
            options.notifyUrl = this.notifyUrl;
            Factory.setOptions(options);
            System.out.println("！！！！！！支付宝SDK初始化成功！！！！！！");
        }
    
        private Config getOptions() {
            Config config = new Config();
            config.protocol = "https";
            config.gatewayHost = "openapi.alipaydev.com";
            config.signType = "RSA2";
            return config;
        }
    
    }

到这里就结束了 请求格式是[http://localhost:自己的端口/aliPayController/pay?&subject=商品名称&traceNo=订单号&totalAmount=价格][http_localhost_aliPayController_pay_subject_traceNo_totalAmount]
