@wendal @wanjunjun 有退款的接口啊！！

Wx_config config = wxConfigService.fetch(mobiOrder.getWxid());
            NutMap payinfo = Json.fromJson(NutMap.class, config.getPayInfo());
            WxApi2 wxApi2 = wxConfigService.getWxApi2(config.getId());
            File file = new File(Globals.AppRoot + "/WEB-INF/cert/wxpay/" + config.getId() + ".p12");
            Map<String, Object> params = new HashMap<>();
            params.put("appid", config.getAppid());
            params.put("mch_id", payinfo.getString("wxpay_mchid"));
            params.put("nonce_str", R.UU32());
            params.put("out_trade_no", mobiOrder.getId());
            params.put("out_refund_no", mobiOrder.getId());
            params.put("total_fee", mobiOrder.getBuyPrice());
            params.put("refund_fee", mobiOrder.getBuyPrice());
            NutMap resp = wxApi2.postPay("https://api.mch.weixin.qq.com/secapi/pay/refund",
                    payinfo.getString("wxpay_key"), params,
                    file,
                    payinfo.getString("wxpay_mchid"));
            log.debug("resp:::" + Json.toJson(resp));
            if ("SUCCESS".equals(resp.getString("return_code"))) {
                //退款成功更新支付状态

            } else {
                
            }

哦，之前没找到。
跟微信交互的api，在返回出来的结果前，加个校验就更方便了。。
帮大家提前规避风险

/**
     * 检查微信api返回结果的签名
     */
    public boolean checkWxResponseSign(NutMap wxResponseMap){
        String wxSign = (String)wxResponseMap.remove("sign");
        String sign = WxPaySign.createSign(appKey, wxResponseMap);
        if(StringUtils.equalsIgnoreCase(wxSign, sign)){
            return true;
        }
        return false;
    }
