[Querydsl] SpringBoot 3.2.x Querydsl 설정하기 (문제 / 해결)

[build.gradle]

plugins {
	id 'java'
	id 'org.springframework.boot' version '3.2.2'
	id 'io.spring.dependency-management' version '1.1.4'
}

group = 'study'
version = '0.0.1-SNAPSHOT'

java {
	sourceCompatibility = '21'
}

configurations {
	compileOnly {
		extendsFrom annotationProcessor
	}
}

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
	implementation 'org.springframework.boot:spring-boot-starter-web'

	implementation 'com.github.gavlyukovskiy:p6spy-spring-boot-starter:1.9.0'

	compileOnly 'org.projectlombok:lombok'
	runtimeOnly 'com.h2database:h2'
	annotationProcessor 'org.projectlombok:lombok'
	testImplementation 'org.springframework.boot:spring-boot-starter-test'

	//test 롬복 사용
	testCompileOnly 'org.projectlombok:lombok'
	testAnnotationProcessor 'org.projectlombok:lombok'

	//Querydsl 추가
	implementation 'com.querydsl:querydsl-jpa:5.0.0:jakarta'
	annotationProcessor "com.querydsl:querydsl-apt:${dependencyManagement.importedProperties['querydsl.version']}:jakarta"
	annotationProcessor "jakarta.annotation:jakarta.annotation-api"
	annotationProcessor "jakarta.persistence:jakarta.persistence-api"

}

tasks.named('test') {
	useJUnitPlatform()
}


clean {
	delete file('src/main/generated')
}

 

 

[gradle 설정]

 

[Gradle -> Tasks -> other -> compile.Java 실행]

 

 

[문제 발생!] Q파일이 작동 되지 않음.

Querydsl 작동 시험 중 Q파일이 참조 되지 않는 문제 발생

 

[querydsl file Tree]

 

[Q 파일 : "Decompiled .class file, bytecode version: 65.0 (Java 21)"]

 

 

[해결 시도 1 : Java 버전 21 -> 17 변환]

 

 

[성공!]

 

[Gradle -> Tasks -> build-> clean 실행] : Q파일을 모두 지우기

[Gradle -> Tasks -> other -> compile.Java 실행] : Q파일을 다시 생성하기
