Spring Boot 시작하기

Spring Boot는 무엇인가?

Server내에서 독립적인 Spring Application을 비교적 간단한 설정 만으로 구동가능하게 해주는 구성 프레임웍이다.

간단한 Boot 예제

목표 : Browser에서 hello JeongHoon, Kim 확인.

git repository 생성

$ git init

Initialized empty Git repository in D:/springboot-note/GettingStart/.git/

Maven을 이용한 프로젝트 생성

mvn -B archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=com.test.app -DartifactId=my-test

Hello.java 생성

package com.test.app;

import org.springframework.boot.*;

import org.springframework.boot.autoconfigure.*;

import org.springframework.stereotype.*;

import org.springframework.web.bind.annotation.*;

@RestController

@EnableAutoConfiguration

public class Example {

@RequestMapping("/")

String home() {

        return "Hello JeongHoon, Kim";

}

public static void main(String[] args) throws Exception {

        SpringApplication.run(Example.class, args);

}

}
