spring boot 통한 웹 서버 뚝딱 만들기

Java 1.8 설치 

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default

Maven 3 설치

wget http://apache.tt.co.kr/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
tar xvzf apache-maven-3.3.9-bin.tar.gz

압축풀린 maven의 bin폴더에서 그 경로를 path에 추가
PATH=$PATH:$PWD

git 설치 
apt-get install git

POM 파일 작성

적절한 위치에 개발 폴더 작성
pom 파일 만든다.

거기 안에

pom.xml 있는 디렉토리에서

mkdir -p src/main/java/myspring

이후, 2 개의 클래스를 만든다.

src/main/java/myspring/Application.java

package myspring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

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

src/main/java/myspring/MyController.java

package misprint;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @RequestMapping("/hello")
    public String hello(@RequestParam(value="name", defaultValue="World") String name) {
        return "Hello" + name;
    }
}

작성 완료되면

mvn compile

하면 필요한 요소들을 다운로드 시작함.

mvn spring-boot:run

을 통해서 런하면

http://host:8080/hello
하면 됨.
