똑같이 작성후 select * from account; 를 해도 아무변화가 일어나지않네요 .. 왜그럴까요? ㅠㅠ 적용이 안된다고 해야하나..

오류는 일어나지않습니다.

package me.whiteship.demospring;


import org.hibernate.Session;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

@Component
@Transactional
public class JpaRunner implements ApplicationRunner {

    @PersistenceContext
    EntityManager entityManager;

    @Override
    public void run(ApplicationArguments args) throws Exception {
       Account account = new Account();
       account.setUsername("whiteship");
       account.setPassword("jpa");

       Session session = entityManager.unwrap(Session.class);
       session.save(account);
    }
}

spring.datasource.url=jdbc:postgresql://localhost:5432/springdata
spring.datasource.username=postgres
spring.datasource.password=pass

spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.jdbc.lob.non_contxtual_creation=true

    public void run(ApplicationArguments args) throws Exception {
       Account account = new Account();
       account.setUsername("aaaaa");
       account.setPassword("jpa");

       Session session = entityManager.unwrap(Session.class);
       session.save(account);

        System.out.println(account.getUsername());
        System.out.println(account.getPassword());
    }
}

이렇게 출력해보니까

나오긴나오는것 같은데 터미널에는 아~무 이상이 없어요 ㅠㅠ email도 추가 되지않았구요

혹시 이것도 관계가 있을가요?

Acces privileges..

데이터베이스 지우면 springdata없다고 인텔리제이에서 오류나고,

생성하면 username, password는 커녕 account 테이블 생성조차 안되네요 ㅠㅠ
