我的webflow配置：

PizzaFlowActions类代码：

@Component

      } else {

      }
   }
   
   public void addCustomer(Customer customer) {
      LOGGER.warn("TODO: Flesh out the addCustomer() method.");
   }

   public Payment verifyPayment(PaymentDetails paymentDetails) {

哥们，你i这问题解决了么？我现在也遇到这个问题了。报错跟你的差不多Property or field 'mysql' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext' - maybe not public?
