注：spring-cloud-starter-gateway和spring-boot-starter-web依赖发生冲突，因为gateway依赖包内置spring-boot-starter-webflux依赖，与web包内的spring-boot-starter-webflux依赖起了冲突。

解决方法

将spring-boot-starter-webspring-依赖包剔除，或剔除boot-starter-webflux依赖包。

1. 剔除web包1. 剔除webflux包     org.springframework.boot     spring-boot-starter-web                              org.springframework.boot               spring-boot-starter-webflux
