복합키 @Idclass 관련질문 입니다!

@Entity
public class Team2 {
    @Id @GeneratedValue
    @Column(name = "team2_id")
    private Long id;
    @Column(name = "team_name")
    private String name;
}

@Entity
@IdClass(memId.class)
public class Member3 {
    @Id
    @Column(name = "member3_id")
    private Long id ;

    @Id                                
    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn(name = "id")
    private Team2 team;

    @Column(name = "username")
    private String username;

@EqualsAndHashCode

public class memId implements Serializable {
    private Long team;
    private Long id;

    public  memId(){}

    public  memId(Long i ,Long o){
        this.id=i;
        this.team=o;
    }

Team2 team =new Team2();
team.setName("many");
em.persist(team);

Member3 member =new Member3();
member.setId(3L);
member.setUsername("HelloB");
member.setTeam(team);
em.persist(member);

Member3 member2 =new Member3();
member2.setId(2L);
member2.setUsername("HelloB");
member2.setTeam(team);
em.persist(member2);

이렇게 만든 후 main 에서 바로 위 코드를 실행한 결과 db에 잘 저장이 되었습니다. 에러코드도 없었구요. Team2 entity 의 id 가 generated value 입니다.

2. equals / hashcode 설정을 했는데도 다른 인스턴스 값을 false 라고 반환합니다. (사진참고부탁드려요)

@EqualsAndHashCode

라고 memId class 에서 넣어주었습니다.

Team2 team =new Team2();
team.setName("many");
em.persist(team);

Member3 member =new Member3();
member.setId(2L);
member.setUsername("HelloB");
member.setTeam(team);


Member3 member2 =new Member3();
member2.setId(2L);
member2.setUsername("HelloB");
member2.setTeam(team);

System.out.println(member.equals(member2));

main에서 위 코드를 실행했는데 false 라고 나옵니다 . @EqualsAndHashcode 를 넣어주었기 때문에 true가 반환되어야 하는게 아닌가요?
