Spring Boot starter reactor netty 依赖错误

如何解决Spring Boot starter reactor netty 依赖错误

我正在学习构建 Spring Boot Websocket Application 的教程。但是，在为 Reactor Netty 添加依赖项后，出现依赖项错误。我试过重新加载项目也无济于事。我是 Reactor Netty 的新手，所以我不太了解它，我是否还需要其他依赖项。

这是我在 pom.xml 中的依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-websocket</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-reactor-netty</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

这是错误：
