HikariDataSource (HikariPool-1)[트랜잭션]
#트랜잭션 설명
##1.트랜잭션의 의미
> 일련의 작업 단위
> 완전히 처리되거나 All-OR-Nothing
##2.소프트웨어에서의 트랜잭션 처리
> 기본적으로(전통적으로) 하나의 함수에 묶어서 처리함.
> 스프링의 경우 그 기준은 비지니스 로직을 처리하는 서비스 단에서의 함수로 묶어버림
###★1)방법 사용
###1)controller(view결정) 함수 1개 끌고옴 << service에서 (비지니스 로직 처리/기능) 댓글달기 << mapper에서 함수 2개 끌고옴
###2)controller 함수 2개 끌고옴 << service : 함수 2개 생성(step update/댓글 insert함수)
##3.스프링에서는 기본적으로 함수, 클래스, 인터페이스 위에 @Transactional로 롤백처리
> 그럼 롤백(트랜잭션은) 언제 일어나는가? → 해당 함수에서 에러, Exception(예외)가 일어났을때
##4.@Transactional과 Checked unChecked Exception과의 관계
