一 通过命令行（Maven构建项目）
相关介绍见下面网页
http://maven.apache.org/archetype/maven-archetype-plugin/generate-mojo.html
二 构建命令
F:\springboot>mvn archetype:generate -DinteractiveMode=false -DgroupId=com.imooc -DartifactId=first-app-by-maven -Dversion=1.0.0-SNAPSHOT
三 构建成功提示
F:\springboot目录下生成项目maven项目first-app-by-maven
四 通过IDEA导入生成的项目模板
五 项目生成后的结构如下
六 pom
1 代码
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.imooc</groupId>
<artifactId>first-app-by-maven</artifactId>
<packaging>jar</packaging>
<version>1.0.0-SNAPSHOT</version>
<name>first-app-by-maven</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>

</project>
2 寻找parent的依赖关系
3 项目依赖关系视图
七 控制器
package com.imooc.web.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloWorldController {
@GetMapping("")
public String index(){
return "Hello World";
}
}
八 主类
package com.imooc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Hello world!
*
*/
@SpringBootApplication
public class App
{
public static void main( String[] args )
{
SpringApplication.run(App.class,args);
}
}
