Spring Boot는 Java 기반 애플리케이션을 쉽게 개발하고 배포할 수 있도록 도와주는 오픈소스 프레임워크예요.
최소한의 설정으로 실행 가능한 독립적인 애플리케이션을 빠르게 만들 수 있도록 도와줍니다 🙌
▶ Start?
모든 시작은... Hello를 출력하면서 시작하죠 ㅎㅎ
이번 글은 제가 처음 만들어본 Spring Boot Hello World 예제를 공유하려고 합니다.
프로젝트 구조를 이해하고, 간단한 컨트롤러를 직접 구현해본 경험을 정리해봤습니다 😊

💡 주요 코드 살펴보기
HelloController.java - /hello 요청을 처리하는 REST 컨트롤러입니다.
@RestController
public class HelloController {
@GetMapping("/hello")
public String hello() {
return "HELLO KIOR BLOG!";
}
}
- @RestController: REST 방식으로 응답을 반환하는 컨트롤러입니다.
- @GetMapping("/hello"):
/hello로 들어오는 GET 요청을 처리합니다. - return "HELLO KIOR BLOG!": 텍스트 응답으로 해당 문구가 출력됩니다.
SpringBootPracticeApplication.java - 프로젝트의 시작점입니다.
@SpringBootApplication
public class SpringBootPracticeApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootPracticeApplication.class, args);
}
}
- @SpringBootApplication: 설정, 컴포넌트 스캔, 자동설정을 모두 포함하는 핵심 어노테이션입니다.
- main(): Spring Boot 애플리케이션의 시작 지점입니다.
🧪 테스트 코드: HelloControllerTest
Web Layer를 테스트하기 위한 단위 테스트 클래스입니다. 컨트롤러가 정상 동작하는지를 확인합니다.
@RunWith(SpringRunner.class)
@WebMvcTest(controllers = HelloController.class)
public class HelloControllerTest {
@Autowired
private MockMvc mvc;
@Test
public void hello가_리턴된다() throws Exception {
String hello = "HELLO KIOR BLOG!";
mvc.perform(get("/hello"))
.andExpect(status().isOk())
.andExpect(content().string(hello));
}
}
- @WebMvcTest: Controller만 로드해서 테스트하는 어노테이션입니다.
- MockMvc: 실제 서버 없이 API 요청/응답을 흉내내는 테스트 도구입니다.
- perform + andExpect:
/hello요청을 보내고, 응답 상태와 내용이 예상과 일치하는지 검증합니다.
📌 이 테스트를 통해 실제 웹 서버를 띄우지 않고도 컨트롤러의 기능을 빠르게 확인할 수 있어요!

📝 마무리
누구나 Hello부터 시작하듯, 이 프로젝트는 Spring Boot 입문의 첫걸음이었습니다 :)
매번 개발서의 앞만 건드렸는데... 작지만 의미 있는 한 발자국! 꾸준하게 추가하며 발전시켜보겠습니다 😄
