pom的依赖问题

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

为什么我在pom中配置以上信息, 项目能够启动起来, 但是配置成和老师的一样就会出问题

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