最简单springboot 项目创建

maven创建

pom.xml

<!-- 第一步：添加Springboot的parent -->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.8.RELEASE</version>
</parent>

<dependencies>

<!-- Springboot依赖 -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>


</dependency>
</dependencies>

package com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@EnableAutoConfiguration
@RestController
public class App {


    public static void main(String[] args) {
        SpringApplication.run(App.class, args);


    }

    @GetMapping("/hello")
    public String hello() {
        return "hello";
    }
}
