doTransaction() 어드바이스의 return 값 의미가 궁금합니다.

@Around("allOrder() && allService()")
public Object doTransaction(ProceedingJoinPoint joinPoint) throws Throwable {
    try {
        log.info("[트랜잭션 시작] {}", joinPoint.getSignature());
        Object result = joinPoint.proceed();
        log.info("[트랜잭션 커밋] {}", joinPoint.getSignature());
        return result;
    } catch (Exception e) {
        log.info("[트랜잭션 롤백] {}", joinPoint.getSignature());
        throw e;
    } finally {
        log.info("[리소스 릴리즈] {}", joinPoint.getSignature());
    }
}

감사합니다.
