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

原因 getaway的pom文件中引用了公用包，公用包包含了spring-boot-starter-web依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

解决方案：只要getawany启动，不包含这个依赖就可以（排除，或者不依赖）

<exclusions>
   <exclusion>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
   </exclusion>
</exclusions>
