Question

I have two tables has one to one relationship as below:

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Book {
  @Id
  @GeneratedValue(stra         


        

Answer 1

You have a circular dependency between book and bookdetails. You probably need to exclude book from BookDetail or bookDetail from Book.

Answer 2

lambok resulted to a circular dependency

reason: the toString() method

solution: replace one of your models to

@Getter
@Setter
public class BookDetail

instead of

@Data
public class BookDetail
