一、该问题的重现步骤是什么？

查找论坛以往帖子，参考了：https://sns.bladex.cn/q-1583.html 和 https://sns.bladex.cn/q-130.html

并没有在blade-common、blade-gateway、blade-service pom文件里边都没有引入springboot-starter-web的相关依赖

启动gateway的时候还是报错，错误信息在下方

最终解决方案是注释掉了gateway里边排除spring-boot-starter-web的代码块。

想问一下这个解决方案对架构有影响吗？如果是这样操作的话那么gateway还是基于webflux的吗？

二、你期待的结果是什么？实际看到的又是什么？

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

四、请提供详细的错误堆栈信息，这很重要。
