发生的错误：

{
  "status" : 1,
  "code" : 0,
  "message" : "It is illegal to call this method if the current request is not in asynchronous mode (i.e. isAsyncStarted() returns false)",
  "param" : null,
  "data" : null
}

与错误发生相关的代码：

@RestController
@RequestMapping(value = "/cashier/v1")
public class PayController {
    @ApiOperation("pay for shop")
    @GetMapping(value = "/pay")
    public ResponseVO<PayResponseVO> pay(ShopPayRequestVO requestVO, HttpServletRequest request) {
        return payService.pay(requestVO, request);
    }
}

@Service
@Slf4j
public class PayServiceImpl implements IPayService {
    @Override
    public ResponseVO<PayResponseVO> pay(ShopPayRequestVO requestVO, HttpServletRequest request) throws AuthorizationException {
        log.info("pay request param:{}", JSON.toJSONString(requestVO));
        PayResponseVO vo = new PayResponseVO();
        ......
        vo.setOrderNo(businessOrderNo);
        vo.setShopId(requestVO.getShopId());
        log.info("pay response param:{}", JSON.toJSONString(vo));
        return ResponseVO.success(vo);
    }
}

@Data
public class PayResponseVO {

    private Object payInfo;

    private String orderNo;

    private String shopId;
}

单步调试所有代码都能正常执行，但前端还是有错误，我遇到了这个错误，但网上没有合适的解决方案，我自己解决了，下面分享解决方案
