Spring boot QueryDsl 세팅 (IntelliJ, maven)

Spring boot QueryDsl 세팅 (IntelliJ, maven)

1. dependency 추가

querydsl-apt: 쿼리 타입(Q-Class)을 생성시 필요
querydsl-jpa: QueryDSL JPA 라이브러리

2. plugIn 추가

pom.xml

        </plugin>
        <!-- QueryDsl setting end -->
    </plugins>
    ...

3. plugin에서 위치 Qclass 경로 target/generated-sources/java 파일 생성 확인

4. 인텔리제이에 Qclass 경로를 추가

상단메뉴 File > Project Structure > Modules > Qclass 경로 > 마우스오른쪽 Sources 추가
