em.save() 부분에서 에러가 납니다.

Spring boot 2.4
junit 5

testImplementation('org.springframework.boot:spring-boot-starter-test') {
    exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}

이부분은 추가했습니다.

package jpabook.jpashop;

import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.annotation.Rollback;
import org.springframework.transaction.annotation.Transactional;

@SpringBootTest
class MemberRepositoryTest {

  @Autowired
  MemberRepository memberRepository;

  @Test
  @Transactional
  @Rollback(value = false)
  public void testMember() {
    Member member = new Member();
    member.setId(1L);
    member.setUsername("member1");

    Long memberId = memberRepository.save(member);
    Member findMember = memberRepository.find(memberId);

    Assertions.assertThat(findMember.getId()).isEqualTo(member.getId());
    Assertions.assertThat(findMember.getUsername()).isEqualTo(member.getUsername());
  }

}

나머지 부분은 다 동일하게 작성했습니다.

테이블은 생성됐으나 이런 에러가 나옵니다.

구글링으로 찾아봐도 1:1, 1:N, N:M 같은 관계설정시 나는 에러같은데 저는 Member 테이블 하나 만들었고, 

package jpabook.jpashop;

import lombok.Getter;
import lombok.Setter;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
@Getter
@Setter
public class Member {

  @Id
  @GeneratedValue
  private Long id;
  private String username;
}

위와 같이 동일하게 작성했습니다 ㅠ

일부러 버전을 다르게 해서 에러나는 부분은 찾아보면서 할려고 이렇게 설정했는데, 혹시나 버전 때문에 나는 에러라면 죄송합니다. 다시 맞추겠습니다.

그게 아니라면 도와주세요...
