Intellij Idea maven hello world

首先看下目录结构

src和pom.xml

pom.xml

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

public class Application extends SpringBootServletInitializer {    public static void main(String[] args) throws Exception {        SpringApplication.run(Application.class, args);    }

}

用idea,选择file-->open这个目录的文件夹，然后以下操作，

右边+号，添加项目，，添加选择pom.xml，这样

加jdk

加下tomcat

右边maven中

filter选中一个环境，比如test,然后

先clean 再compile

最后点击启动，会出现启动成功页面：

你好！这是我的首页！
