1. Spring 설치 on Mac - Spring 사용하기

Spring 2019. 7. 31. 15:02

source code : https://github.com/kgmhk/spring-boot-tutorial/tree/spring-install

1. 필요한 설치

선호하는 IDE
- Visual Studio or intellij 등등
JDK 1.8 or later
- 아래 링크에서 JDK 설치
- https://www.oracle.com/technetwork/java/javase/downloads/index.html
Gradle 4+ or Maven 3.2+ 설치
- Gradle과 Maven은 빌드툴로써 Maven 은 Apache에서 2004년에 만들어졌으며 Gradle은 Maven과 Ant의 장점을 모아 2014년 출시된 빌드툴.
- 아래 링크를 통해 각가 설치 가능
- Gradle : https://gradle.org/install/
- Maven: https://maven.apache.org/download.cgi
- Gradle 설치 방법
  - java 설치 확인 및 brew를 이용한 설치 or binary를 직접 다운로드 받아서 설치

$ java -version
java version "12.0.1" 2019-04-16
Java(TM) SE Runtime Environment (build 12.0.1+12)
Java HotSpot(TM) 64-Bit Server VM (build 12.0.1+12, mixed mode, sharing)

$ brew install gradle

2. Gradle build 파일 생성

project 폴더 생성

$ mkdir -p ~/helloworld/src/main/java/hello

build.gradle 파일 생성

$ vi ~/helloworld/build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:2.1.6.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

bootJar {
    baseName = 'helloworld'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    testCompile("junit:junit")
}

3. Application 생성을 위한 Class 작성

HelloController.java 작성

$ vi ~/helloworld/src/main/java/hello/HelloController.java

package hello;

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

@RestController
public class HelloController {

    @RequestMapping("/")
    public String index() {
        return "Greetings from Spring Boot!";
    }

}

Application.java 작성

$ vi ~/helloworld/src/main/java/hello/Application.java

package hello;

import java.util.Arrays;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class Application {

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

    @Bean
    public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
        return args -> {

            System.out.println("Let's inspect the beans provided by Spring Boot:");

            String[] beanNames = ctx.getBeanDefinitionNames();
            Arrays.sort(beanNames);
            for (String beanName : beanNames) {
                System.out.println(beanName);
            }

        };
    }

}

4. Gradle을 이용한 Build 및 실행

gradle build

$ gradle build && java -jar build/libs/helloworld-0.1.0.jar

5. 실행 확인

$ curl localhost:8080

Greetings from Spring Boot!

6. route (api) 추가 해보기

http://localhost:8080/hello 호출 시 "hello world"가 response 되는 api 추가
HelloController.java를 아래와 같이 수정

package hello;

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

@RestController
public class HelloController {

    @RequestMapping("/")
    public String index() {
        return "Greetings from Spring Boot!";
    }

    @RequestMapping("/hello")
    public String hello() {
        return "Hello world";
    }

}

재 빌드

$ gradle build && java -jar build/libs/helloworld-0.1.0.jar

확인

$ curl localhost:8080/hello
Hello world
