pom.xml里spring-boot-starter-webs

解决：

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-websocket</artifactId>
      <version>3.0.2</version>
    </dependency>

项目需要引入websocket

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

网上提示这样导入，但是爆红
