[Kotlin] QueryDSL 자료

• 설정
  • https://olkkani.github.io/spring/start-kotlin-springboot-projct/config-querydsl-for-kotlin-springboot/
  • kapt 인식안되면, gradle refresh 하기.
  • EntityManager import할 때 jakarta 아니라 javax 로 하기

밑에꺼 다 안됨.

• Qclass가 계속 생성이안돼서 미치는줄 알았다.
• 이유가 kapt 버전이 중요한듯
  
• 1.8.21 로 했더니 됐다. ㅠㅠ

plugins{
    kotlin("kapt") version "1.8.21"
}
dependencies {
// QueryDSL
    implementation("com.querydsl:querydsl-jpa:5.0.0:jakarta")
    kapt("com.querydsl:querydsl-apt:5.0.0:jakarta")
    testImplementation("org.springframework.boot:spring-boot-starter-test")
}

build.gradle.kts 설정

plugins {
    id("idea")
    kotlin("kapt") version "1.7.10"
}

dependencies {
// QueryDSL
    implementation("com.querydsl:querydsl-jpa:5.0.0")
    implementation("com.querydsl:querydsl-apt:5.0.0")
    implementation("javax.annotation:javax.annotation-api:1.3.2")
    implementation("javax.persistence:javax.persistence-api:2.2")
    annotationProcessor(group = "com.querydsl", name = "querydsl-apt", classifier = "jpa")
    kapt("com.querydsl:querydsl-apt:5.0.0:jpa")
}

// Kotlin QClass Setting
kotlin.sourceSets.main {
    println("kotlin sourceSets builDir:: $buildDir")
    setBuildDir("$buildDir")
}

idea {
    module {
        val kaptMain = file("build/generated/source/kapt/main")
        sourceDirs.add(kaptMain)
        generatedSourceDirs.add(kaptMain)
    }
}
    

QuerydslConfiguration 설정

import com.querydsl.jpa.impl.JPAQueryFactory
import javax.persistence.EntityManager
import javax.persistence.PersistenceContext
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration

@Configuration
class QuerydslConfiguration (
    @PersistenceContext
    private val entityManager: EntityManager
) {
    @Bean
    fun jpaQueryFactory(): JPAQueryFactory = JPAQueryFactory(entityManager) }
