Answer 1

使用https://start.spring.io/创建初始pom / spring引导应用程序。您可以稍后根据需要添加依赖项。

Answer 2

您不需要在tomcat中部署spring-boot项目，spring-boot具有自己的服务器来运行应用程序。 因此，当您在服务器上部署应用程序时，借助Maven，我们可以构建并运行spring-boot应用程序。 这是在Linux中运行build和运行应用程序的命令。

mvn全新安装

nohup mvn spring-boot：run

如果要重新启动服务器，则需要终止端口ID

lsof -i：appPortNumber

杀死-9 processIdOfPort

Answer 3

我认为，您正在尝试在本地运行应用程序。 Spring Boot应用程序内置了tomcat服务器。 为了在eclipse中运行您的应用程序，     1）右键单击您的项目-> 2）转到运行方式-> 3）Java应用程序 您的应用程序将启动。

在pom中还添加了devTools的依赖项，因此，如果您对代码进行了任何更改，服务器将自动重新启动。
