| Review.java

		 name = "REVIEW_SEQ_GENERATOR",
		 sequenceName = "REVIEW_SEQ", //매핑할 데이터베이스 시퀀스 이름

	@JoinColumn(name = "num")
	@GeneratedValue(strategy = GenerationType.SEQUENCE,
	   generator = "REVIEW_SEQ_GENERATOR")
	private Long rNum;
	
	@ManyToOne
//	(

//					CascadeType.MERGE //머지쓰면 update된다. 즉 유저 한명당 리뷰 하나만...가능..!
//					})
	@JoinColumn(name = "user_id")
	private User user;
	
	@Column(name = "sort")
	private int sort;
	
	@Column(name = "title")
	private String title;
	
	@Column(name = "content")
	private String content;
	
	@Column(name = "created_date")
	private LocalDateTime createdDate;
	
	@Column(name = "stars")
	private float stars;
	
	@OneToOne
	@JoinColumns({@JoinColumn(name = "order_num"),
		@JoinColumn(name = "prod_num")})
	private OrderDetail orderDetail;
	
	@OneToOne(mappedBy = "review")
	private BestReview bestReview;
	
}

| BestReview.java

@Setter @Getter @AllArgsConstructor @NoArgsConstructor
@Entity
@Table(name="best_review")
@DynamicInsert
@DynamicUpdate
public class BestReview {
	@Id
	@Column(name = "review_num")
	private Long rNum;
	
	@MapsId
	@OneToOne
	@JoinColumn(name = "review_num")
	private Review review;
	
	@Column(name = "created_date")
	private LocalDateTime createdDate;
}

문제는, 종속관계인 BestReview 쪽에 CascadeType.ALL을 지정해주지 않아서 rNum이 null로 들어가고 있었다.

따라서,

| BestReview.java

@Setter @Getter @AllArgsConstructor @NoArgsConstructor
@Entity
@Table(name="best_review")
@DynamicInsert
@DynamicUpdate
public class BestReview {
	@Id
	@Column(name = "review_num")
	private Long rNum;
	
	@MapsId
	@OneToOne(cascade = CascadeType.ALL) //<-- 요고!! 필수
	@JoinColumn(name = "review_num")
	private Review review;
	
	@Column(name = "created_date")
	private LocalDateTime createdDate;
}

• insert가 잘 되는 것을 볼 수 있다.
