## AlipayConfig.java 

只需要获取配置alipay的参数即可
```java
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;

}
```

## 参数AliPay.java
```java
import lombok.Data;

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

        }
        return "success";
    }
}
```


## 实现回调功能

- 加配置(前端支付页面的地址)：alipay.returnUrl=http://localhost:8080/orders
- AlipayConfig.java 加一个属性：returnUrl
- AliPayController.java的pay接口设置回调的url：request.setReturnUrl(aliPayConfig.getReturnUrl());

## 页面调用

window.open('http://localhost:9090/alipay/pay?traceNo=' + row.orderNo + "&totalAmount=" + row.price + '&subject=' + row.name)

以上即全部的内容，配置完之后就可以实现了
