***************************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.

解决方案：

网关异常报Consider defining a bean of type 'org.springframework.http.codec.ServerCodecConfigurer' in your configuration，
是因为项目引入了spring-boot-starter-web,因为会与spring cloud gateway的webflux冲突。所以项目不要引入spring-boot-starter-web。

本案例是删除spring-boot-starter-web的引入
