위와 같이 콘솔에 찍히는 sql 문이 정열되지 않게 보입니다.

윈도우에 설치된 인텔리제이는 무료버전을 사용하고 있고

설정된 application.yml은 아래와 같습니다.

spring:
datasource:
url: jdbc:h2:tcp://localhost/~/shop
username: sa
password:
driver-class-name: org.h2.Driver

jpa:
hibernate:
ddl-auto: create
properties:
hibernate:
# show-sql: true
format-sql: true
default_batch_fetch_size: 100



logging:
level:
org.hibernate.SQL: debug
# org.hibernate.type: trace

콘솔에 sql문이 정렬되게 하는 방법은 무엇인가요?

감사합니다. 잘 작동합니다.^^

datasource 가 1개인 경우 yml 파일에만 지정하면 format_sql 도 잘되고 default_batch_fetch_size 도 잘 되는데요. 멀티 datasource 를 사용중이라 JPAConfig 클래스를 만들어서 사용하면 default_batch_fetch_size 프로퍼티는 아래 properties 에 값을 넣으면 되는데요. format_sql 은 안먹네요 ????

-> yml 파일에 등록해도 안되서 default_batch_size 는 아래 속성값에 추가하니까 되었는데요. format_sql 은 안되네요..

안녕하세요. 개발자님^^

format-sql -> format_sql 로 변경하시면 됩니다^^
