<p>Member엔티티에서 지금 강의에서는 id를 그냥&nbsp;</p>
<div>
<div>@GeneratedValue만 쓰시잖아요?</div>
<div>제가 SEQ를 만들어서 넣고싶어서 열심히 인터넷을 찾아보니</div>
</div>
<div>
<div>&nbsp;</div>
<div>@Entity</div>
<div>
<div>@SequenceGenerator(</div>
<div>&nbsp; name = MEMBER_SEQ_GENERATOR",</div>
<div>&nbsp; sequenceName = "MEMBER_SEQ",&nbsp;</div>
<div>&nbsp; initialValue = 1,</div>
<div>&nbsp; allocationSize = 1)</div>
@Getter @Setter<br>public class Member {</div>
<div><br>&nbsp;@Id @GeneratedValue
<div>
<div>(strategy = GenerationType.SEQUENCE,</div>
<div>&nbsp; &nbsp; generator = "MEMBER_SEQ_GENERATOR")</div>
</div>
&nbsp;private Long id;<br>&nbsp;private String username;<br>&nbsp;</div>
<div>요렇게하니까 seq가 생성되더라구요,</div>
<div>&nbsp;</div>
<div>그럼 여기서질문이있는데, 기존 DB에서 seq는 nextVal 같이 미리 다음시퀀스값을 가져올수있는기능이있는데,</div>
<div>&nbsp;</div>
<div>jpa에서는 어떻게 그런기능을 구현하나요?</div>
<div>&nbsp;</div>

<p><span style="font-family: Arial;">엔티티 정보를 바탕으로 sequence generator를 세션팩토리에 등록해둡니다.</span></p>
<p><span style="font-family: Arial;">필요할 때마다 해당 sequence generator를 참고하여 id 값을 생성하게 됩니다.</span></p>
