public String qrCode(@RequestBody @Validated TradeDTO tradeDTO, BindingResult result) throws AlipayApiException{
if (result.hasErrors()) {
throw new BindingResultException(result);

request.setNotifyUrl("");
JSONObject bizContent = new JSONObject();
bizContent.put("out_trade_no", tradeDTO.getOutTradeNo());
bizContent.put("total_amount", tradeDTO.getTotalAmount());
bizContent.put("subject", tradeDTO.getSubject());
request.setBizContent(bizContent.toString());
AlipayTradePrecreateResponse response = alipayClient.execute(request);
if(response.isSuccess()){
return response.getBody();
} else {
throw new BusinessException(ResultCode.ADD_ACCOUNT.getCode(), "二维码生成失败失败");

import QRCode from 'qrcodejs2'
data() {
return {
successInfo: {},
dialogVisible: false,
TradeForm: {
//订单编号

getQRCode() {
let qr;
this.TradeForm.outTradeNo = this.getProjectNum();
console.log(this.TradeForm.outTradeNo)
this.TradeForm.totalAmount = this.orderInfo();
