plugins {
	id("org.springframework.boot") version "3.4.2"
	id("io.spring.dependency-management") version "1.1.7"
	id("java")
	id("org.jetbrains.kotlin.jvm") version "1.9.25"
	id("org.jetbrains.kotlin.plugin.jpa") version "1.9.25"

	id("org.jetbrains.kotlin.kapt") version "1.9.25"
}

group = "com.contact"
version = "0.0.1-SNAPSHOT"

java {
	toolchain {
		languageVersion.set(JavaLanguageVersion.of(17))
	}
}

repositories {
	mavenCentral()
}

dependencies {
	implementation("org.springframework.boot:spring-boot-starter-data-jpa")
	implementation("org.springframework.boot:spring-boot-starter-web")
	implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")

	implementation("com.fasterxml.jackson.module:jackson-module-kotlin")

	runtimeOnly("com.h2database:h2")
	testImplementation("org.springframework.boot:spring-boot-starter-test")
}

tasks.withType<Test> {
	useJUnitPlatform()
}

tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
	kotlinOptions {
		jvmTarget = "17"
	}
}

 

4. New - Kotlin Class/File 클릭후 TestController 생성

 

5. TestController.kt

package com.contact.management.controller

import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RestController

@RestController
class TestController {

    @GetMapping("/test")
    fun test(): String{
