gradle 세팅


buildscript {
    ext {
        queryDslVersion = "5.0.0"
    }
}
plugins {
		...
    id "com.ewerk.gradle.plugins.querydsl" version "1.0.10"
}
configurations {
		...
    querydsl.extendsFrom compileClasspath // queryDsl
}
dependencies {
		...
    implementation "com.querydsl:querydsl-jpa:${queryDslVersion}"
    implementation "com.querydsl:querydsl-apt:${queryDslVersion}"
}


def querydslDir = "$buildDir/generated/querydsl"
querydsl {
    jpa = true
    querydslSourcesDir = querydslDir
}

sourceSets {
    main.java.srcDir querydslDir
}
compileQuerydsl {
    options.annotationProcessorPath = configurations.querydsl
}

Config 파일 작성


@Configuration
public class QueryDslConfig {

    @PersistenceContext
    private EntityManager entityManager;

    @Bean
    public JPAQueryFactory jpaQueryFactory() {
        return new JPAQueryFactory(entityManager);
    }

}

QueryDsl 적용

custom queryDsl repository interface 생성


public interface Query${Entity}Repository {
		// custom Method-Signature
}

queryDsl interface 구현체 작성


@Repository
@RequiredArgsConstructor
public class Query${Entity}RepositoryImpl implements Query${Entity}Repository {

    private final JPAQueryFactory jpaQueryFactory;
		
		// interface 구현

}

JPA와 연동


public interface ${Entity}Repository 
									extends JpaRepository<${Entity}, Long>, Query${Entity}Repository{
}
