Java 使用Tomcat部署Spring Boot

我想部署我的第一个Java应用程序——我有地方部署它。我用Tomcat制作了Spring Boot应用程序。使用一些web指令，我制作了一个fatjar文件（maven包）。我有例外。我试图寻找它，但任何解决方案都不适用于此

我可以添加什么-我不设置Tomcat，简单的基于maven包jar和Tomcat。有人能告诉我我能做什么吗？我将非常感谢您的理解和帮助。这是我第一次部署

这里有一些要检查的项目

1-确保在POM中包含Tomcat依赖项

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

3-如果这是在linux环境中运行的，请尝试在VM中运行以下应用程序：

-Dserver.port=8181

4-确保应用程序类扩展SpringBootServletilizer：

@SpringBootApplication  
public class App extend SpringBootServletInitializer
{
    public static void main( String[] args )
    {
        SpringApplication.run(App.class, "hello");
    }
}

您似乎没有配置有效的端口，它应该>1024。

您似乎没有配置有效的端口，它应该>1024。

您可以包括您的应用程序代码和配置吗？您是否在windows计算机上开发应用程序并在linux机上运行它？您是否尝试使用机器上的知名端口（如80）？如果是这种情况，您需要以超级用户权限运行该程序。如果没有，请检查端口是否已使用。是否可以包括应用程序代码和配置？是否在windows计算机上开发应用程序并在linux计算机上运行？您是否尝试使用机器上的知名端口（如80）？如果是这种情况，您需要以超级用户权限运行该程序。如果没有，请检查端口是否已使用。谢谢！这是帮助！谢谢这是帮助！
