jpa가동 시 EntityManager NPE 발생 ㅜㅜ

Question

안녕하세요jpa 테스트중인데 EntityManagerFactory, EntityManager에서 널포인트에러가 발생합니다....어디가 잘못되었는지 감도 안잡혀서 문의드립니다.아래는 작성한 코드입니다. JUnit 테스트하고 있습니다.package com.my.practice.test;import java.util.Date;import javax.persistence.EntityManager;import javax.persistence.EntityManagerFactory;import javax.persistence.EntityTransaction;import javax.persistence.Persistence;import javax.persistence.PersistenceContext;import org.junit.Test;import org.junit.jupiter.api.AfterEach;import org.junit.jupiter.api.BeforeAll;import org.junit.jupiter.api.BeforeEach;import org.springframework.stereotype.Repository;import com.my.practice.vo.MemberVo;import lombok.extern.slf4j.Slf4j;&#64;Slf4j&#64;Repositorypublic class MemberEntityTest { private static EntityManagerFactory emf; &#64;PersistenceContext private EntityManager em; private EntityTransaction tx; &#64;BeforeAll public static void setFactory() { emf &#61; Persistence.createEntityManagerFactory(&#34;MemberEntityTest&#34;); } &#64;BeforeEach public void setUp() { em &#61; emf.createEntityManager(); tx &#61; em.getTransaction(); tx.begin(); } public EntityManager getEntityManager() { return emf.createEntityManager(); } &#64;Test public void memberEntityTest() { Date today &#61; new Date(); MemberVo member &#61; MemberVo.builder() .memNo(1L) .name(&#34;hong gil dong&#34;) .id(&#34;hgd12&#34;) .passwd(&#34;dongdong1234&#64;&#64;&#34;) .age(23) .gender('M') .leg_date(today) .build(); em.persist(member); em.getTransaction().commit(); MemberVo selected &#61; em.find(MemberVo.class, 1); log.info(&#34;selected: {}&#34;, selected); System.out.println(&#34;sysout: selected: &#34;&#43;selected); } &#64;AfterEach public void cleanup() { tx.commit(); em.close(); }}

&#64;Repository가 &#64;Bean을 상속하고 있는데 private static EntityManagerFactory emf 구문을 static으로 하시면 안되는 거 아닌가요? 이러면 생성자에서 초기화해줘야해서 emf가 초기화될 방법이 없을 것 같습니다.

&#64;Autowiredprivate EntityManagerFactory emf;이렇게 하면 결과가 바뀔거 같네요.
