i have many to many relationship between book and author, i have 3 tables: author, book and author_book.
@Entity()
@Table(name = "author")
@NamedEntityGraph(name = "Book.detail", attributeNodes = @NamedAttributeNode("books"))
@Getter
@Setter
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Author {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
@ManyToMany
@JoinTable(
name = "author_book",
joinColumns = @JoinColumn(name = "author_id"),
inverseJoinColumns = @JoinColumn(name = "book_id")
)
private List<Book> books;
}
and
@Entity()
@Table(name = "book")
@Getter
@Setter
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Book {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
@ManyToMany(mappedBy = "books")
private List<Author> authors;
}
With repositories:
public interface AuthorRepository extends JpaRepository<Author, Long>{
@EntityGraph(value = "Book.detail", type = EntityGraphType.LOAD)
Author getGraphById(Long id);
Author getById(Long id);
}
and
public interface BookRepository extends JpaRepository<Book, Long>{
}
In AuthorRepository, i have 2 methods: getGraphById() to load books with author, getById() to not load books.
The problem is when using @test tag (jUnit test) everything works as expected, but when i call api via postman both methods load books and it is infinite like ( books -> authors-> books -> authors-> ... ).
