springboot集成springCloud中gateway时启动报错

在项目中引入springcloud中的gateway时报以下错误

Description:

Parameter 0 of method modifyRequestBodyGatewayFilterFactory in org.springframework.cloud.gateway.config.GatewayAutoConfiguration 
required a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' that could not be found.

Action:
Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration.

这个是由于依赖冲突，spring-cloud-starter-gateway与spring-boot-starter-web和spring-boot-starter-webflux依赖冲突

解决方式：在引入gateway时过滤掉上面两个依赖

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