按照网上尝试过的教程，在父pom工程的<dependencyManagement>中去除spring-boot-starter-web依赖，并在需要此依赖的子模块中重新以GAV坐标的方式引用无法解决问题，以下是解决问题的方法。

问题复现

spring boot版本和spring cloud版本

框架	版本
SpringBoot	2.3.0.RELEASE
SpringCloud	Hoxton.SR5

gateway中的依赖

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>
    
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-gateway</artifactId>
    </dependency>

依赖冲突

发现存在spring-cloud-starter-gateway和spring-boot-starter-web依赖发生冲突

检查依赖

在gateway的依赖树中搜索spring-boot-starter-web依赖

发现是eureka依赖spring-cloud-starter-netflix-eureka-server引入了spring-boot-starter-web
删除依赖再次尝试，发现去除了web依赖后缺少其他依赖

尝试手动添加这些依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
    <version>${spring-boot.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.2.7.RELEASE</version>
</dependency>

问题解决！！！
