## 支付宝退款
`创建支付Key等操作，参考支付宝APP支付或支付宝PC扫码支付文档`

调用退款的demo
```groovy
import com.zhc.eap.alipay.model.vo.AlipayAppOrderResultVO;
import com.zhc.eap.alipay.model.vo.AlipayRefundOrderResultVO;
import com.zhc.eap.alipay.model.vo.AlipayRefundQueryResultVO;
import com.zhc.eap.alipay.model.pojo.AlipayOrderNotifyResult;
import com.zhc.eap.alipay.model.pojo.AlipayOrderRefundResult;
import com.zhc.eap.alipay.service.ZhcAlipayService;
import com.zhc.eap.context.SpringContextHolder;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

class alipayPayment {
    //生成接口订单
    public static void refundOrder(HttpServletRequest request,HttpServletResponse response){
        String configId = ""; // configId 为部署里面的projectDefVal中定义的configId
        String funcId = ""; // 自定义的funcId
        String orderNo = ""; // 订单号
        int money = ""; // 金额，单位为分
        ZhcAlipayService alipayService = SpringContextHolder.getBean(ZhcAlipayService.class);
        AlipayRefundOrderResultVO resultVO = alipayService.refundOrder(configId, funcId, orderNo, money1);
        String body = resultVO.getBody();
    }
}
```

查询退款接口是否成功
```groovy
String configId = ""; // configId 为部署里面的projectDefVal中定义的configId
String funcId = ""; // 自定义的funcId
String orderNo = ""; // 订单号
ZhcAlipayService alipayService = SpringContextHolder.getBean(ZhcAlipayService.class);
AlipayRefundQueryResultVO resultVO = alipayService.refundQuery(configId, funcId, orderNo);
String body = resultVO.getBody();
```
