Я хочу определить одно поле в таблице question_response как список чисел.
@Entity
public class QuestionResponse {
@Id
@GeneratedValue(strategy= GenerationType.AUTO)
@Column(name="question_response_id", nullable = false, updatable = false)
private Long question_response_id;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "user_uuid")
private User users;
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "question_id")
private Question questions;
private List<Long> questionAns;
}
Но выдает ошибку:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.MappingException: Could not determine type for: java.util.Set, at table: question_response, for columns: [org.hibernate.mapping.Column(question_ans)]
Я также пытался установить, но не работал.Кто-нибудь может мне помочь с этим?
