MemberRepositoryTest에서 java.lang.IllegalStateException: Failed to load ApplicationContext

안녕하세요.섹션 1의 마지막 강의 jpa와 DB설정, 동작확인 강의를 수가중에, 12분지점까지 따라해왔습니다. 그런데 이러한 에러가 발생하고 이유를 못찾겠습니다..

java.lang.IllegalStateException: Failed to load ApplicationContext

build.gradle에서는 junit4를 사용하고자 기존의 질문글들을 보고아주 조금 수정했습니다.

plugins {
	id 'java'
	id 'org.springframework.boot' version '2.7.15'
	id 'io.spring.dependency-management' version '1.0.15.RELEASE'
}

group = 'jpabook'
version = '0.0.1-SNAPSHOT'

java {
	sourceCompatibility = '11'
}

configurations {
	compileOnly {
		extendsFrom annotationProcessor
	}
}

repositories {
	mavenCentral()
}

dependencies {
	implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
	implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
	implementation 'org.springframework.boot:spring-boot-starter-web'

	compileOnly 'org.projectlombok:lombok'
	runtimeOnly 'com.h2database:h2'
	annotationProcessor 'org.projectlombok:lombok'
	testImplementation 'org.springframework.boot:spring-boot-starter-test'
//	JUnit4 추가
	testImplementation("org.junit.vintage:junit-vintage-engine") {
		exclude group: "org.hamcrest", module: "hamcrest-core"
	}
}

tasks.named('test') {
	useJUnitPlatform()
}

문제의 테스트입니다.

package jpabook.jpashop;

import org.assertj.core.api.Assertions;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.transaction.annotation.Transactional;

import static org.junit.Assert.*;

@RunWith(SpringRunner.class)
@SpringBootTest
public class MemberRepositoryTest {

    @Autowired MemberRepository memberRepository;

    @Test
    @Transactional
    public void testMember() throws Exception {
        Member member = new Member();
        member.setUsername("memberA");

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

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

    }
}

비단 테스트뿐 아니라, 애플리케이션도 실행에 실패를 하는데, 위의 에러중 이부분이 문제가 아닌가 싶습니다... ㅠㅠ
