尝试运行我的应用程序后，主类出现在这里：

@SpringBootApplication public class RappersInfo {

    public static void main(String[] args) {

SpringApplication.run(RappersInfo.class, args);

    }   @Component
    public class JspContextCustomizer implements TomcatContextCustomizer {
        @Override
        public void customize(Context context) {
            JspPropertyGroup group = new JspPropertyGroup();
            group.addUrlPattern("/*");
            group.setPageEncoding("UTF-8");
            context.setJspConfigDescriptor(new JspConfigDescriptorImpl(
                    Collections.singletonList(new JspPropertyGroupDescriptorImpl(group)),
                    Collections.emptyList()));
        }
    }
}

在尝试运行该类后，我得到了该错误：

</project>```

 What can i do?

Tried almost everything what was in the internet.

Error happens after changing spring boot version from 3.x. to 2.7.6 (i want to deploy it with war file). Im not sure about my pom.xml. Maybe there is a problem with tomcat dependencies?

如果您的地址或端口不正确或已被使用，也会发生类似的错误。这可以修复大多数情况下的错误，但像上面提到的驱动程序可能会导致错误。
尝试将端口号从8080更改为其他值，如果这还不够，那么我遇到的另一个示例如下：
有控制软件安装的个人网络接口控制器（网卡），允许以太网和wifi同时使用。这是安装理应改善游戏体验，但没有发挥良好的Tomcat在 Spring 。一旦禁用应用程序能够运行预期。它描述如下：
这是一个安装卡的网络接口卡尔驱动程序。它将根据安装的卡和驱动程序而不同-您可以通过查看windows上的设备管理器来查看您的驱动程序。
希望对你有帮助！！

禁用Gamingservices服务或转到任务管理器并结束Gamingservices的任务，然后再次运行应用程序。或重新启动计算机。
