새 프로젝트 생성
인텔리제이 File → New → Project…
JDK : 원하는 jdk 버전 등록
Gradle DSL : Kotlin
인텔리제이 환경설정 (File → Settings)
Editor → File Encodings
Build, Execution, Deployment → Build Tools → Gradle
- Gradle user home : 사용하는 Gradle 버전 불러오기
Build, Execution, Deployment → Compiler → Annotaion Processors
외부 라이브러리 의존성 주입
build.gradle.kts
plugins {
id("java")
id("war")
}
group = "org.example"
version = "1.0-SNAPSHOT"
repositories {
mavenCentral()
}
dependencies {
testImplementation("org.springframework:spring-test:4.2.0.RELEASE")
testImplementation("junit:junit:4.12")
compileOnly("org.projectlombok:lombok:1.18.22")
compileOnly("javax.servlet:javax.servlet-api:3.1.0")
implementation("org.springframework:spring-context:4.2.0.RELEASE")
implementation("org.springframework:spring-webmvc:4.2.0.RELEASE")
}
tasks.test {
useJUnitPlatform()
}- plugins 에 id(”war”) 추가
- 각 라이브러리의 버전은 본인 프로젝트에 맞게 지정
웹 프로젝트 구성
src → main 폴더 하위에 webapp 디렉토리 생성
webapp 하위에 WEB-INF 폴더 생성
web.xml 생성
File → Project Structure
📌 build.gradle.kts 에 id("war") 를 추가하지 않았다면 아티팩트가 나타나지 않음
- Facets에서 Web 항목의 아티팩트를 선택하고 우측의 + 버튼을 클릭하여 web.xml 추가
- webapp > WEB-INF 하위에 위치하도록 조정
root-context.xml 생성
WEB-INF 하위에 views폴더, spring 폴더 생성, spring 하위에 appServlet 폴더 생성
spring 폴더 내에 root-context.xml 생성
spring 우클릭 → New → XML Configuration File → Spring Config
root-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
</beans>- 자동 생성된 내용은 건들지 않습니다.
servlet-context.xml 생성
root-context.xml 와 같은 방식으로 appServlet 폴더 내에 servlet-context.xml 생성
servlet-context.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>- 위와 같이 내용 수정
Controller 클래스 생성
-
src → main → java → 그룹 에 있던 main.java 삭제
-
controller 패키지 추가 후 컨트롤러 클래스 생성
-
servlet-context.xml 수정
<?xml version="1.0" encoding="UTF-8"?>

</bean>
<context:component-scan base-package="org.example.controller"/>
</beans>- 컨트롤러를 스캔할 수 있도록 방금 생성한 controller 패키지 정보 추가
web.xml 내용 수정
<?xml version="1.0" encoding="UTF-8"?>

Run → Edit Configurations… 클릭
- Application server : 다운받아 놓은 톰캣 지정
- VM options : 한글 깨짐 방지를 위해 -Dfile.encoding=UTF-8 입력
- HTTP port, JMX port: 원하는 포트로 지정
Deployment 탭에서 Artifact 추가
Application context 는 / 만 남도록 수정
컨트롤러 및 뷰 페이지 생성 후 테스트
Controller
package org.example.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String home() {
return "index";
