是退款回调，在 parseOrderNotifyResult 这一步抛出异常

// 支付回调通知处理
@PostMapping("/refund")
public String refund(@RequestBody String xmlData) {
    log.info("wx refund notify: xml={}", xmlData);

    try {
        final WxPayOrderNotifyResult result = wxService.parseOrderNotifyResult(xmlData);
        log.info("wx refund notify result: {}", result);
        // 退款成功, 更改充值卡状态
        
    } catch (Exception e) {
        e.printStackTrace();
    }

    // 返回必须按照微信的格式！
    return WxPayNotifyResponse.success("成功");
}

我也遇到同样的问题，求解答！！
