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