使用仅包含 Spring Web 依赖项的 Maven 的 Spring 应用程序会出现“无法启动嵌入式 Tomcat 服务”错误。

同一个项目像预期的那样在其他计算机上运行。

Spring Boot 版本：2.4.3
包类型：JAR
Java 版本：11

除了打印到控制台进行测试之外，没有从入门项目添加其他代码。

当在 pom.xml 中排除 tomcat 时，应用程序会像预期的那样运行并打印到控制台。
测试了多个端口。
测试了 JDK 8 和 11。

pom.xml 依赖项：

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

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

为个人网络接口控制器 (NIC) 安装了控制软件，允许同时使用以太网和 wifi。安装它是为了改善游戏体验，但在 Spring 中与 tomcat 并不能很好地发挥作用。禁用后，应用程序能够按预期运行。
