spring-cloud-starter-gateway依赖与mvc是不兼容的,如果要引用spring-boot-starter-web需要把mvc排除
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </exclusion> </exclusions> </dependency>
