기 생성된 DB 테이블을 자동으로 Entity 객체를 생성해 주면서 Queryfactory 객체까지 추가로 생성

환경

 - Maven

 

 

프로젝트 git 풀 소스

 

ppusarida / EntityAutoCreation

 

소스추가

 

POM.xml  파일에 아래 추가1~추가3 을 적용합니다.

DB 접속 주소와 계정이 연결할 수 없으면 아래 <execution> 에 빨강줄이 생기면서 오류가 발생하는점 참고 바랍니다.

코드 자동생성하기

 프로젝트 우클릭 -> Run As ->  Maven Generate-sources 하면 아래 스샷처럼 Entity와 queryDsl을 활용할 수 있는 query-factory 클래스가 자동으로 생성된다.

 

사용방법

생성된 소스를 src/main/java 이하 패키지로 카피하여 사용하시면 됩니다.
