Spring MVC found on classpath, which is incompatible with Spring Cloud Gateway at this time. Please remove spring-boot-starter-web dependency.

问题:一开始查都是说引用了  spring-boot-starter-web 和gateway的冲突,具体冲突可以百度

有的直接删掉就好了,但是并没有

结果是断路器的监控导致的

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
    </dependency>

这里面也有引用
