Я пытаюсь использовать JPA в первый раз, и я немного борюсь с этой ошибкой. Вот мой основной класс. Все остальные мои занятия находятся в подпакетах.
@SpringBootApplication
@ImportResource({"classpath*:/META-INF/**/spring-bootstrap.xml"})
@EnableJpaRepositories
public class Application { .... }
А вот и мой репозиторий
@Repository
public interface JobRepository extends JpaRepository<Job, Long>{
}
Моя работа Пойо
@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
@Entity
@Table(name="whatever")
public class Job implements Comparable<Job>, Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
Но когда я запускаю его, я получаю сообщение об ошибке при создании компонента с именем 'jobRepository': не удается разрешить соответствующий конструктор (подсказка: укажите аргументы index / type / name для простых параметров, чтобы избежать неоднозначности типов)
Поскольку SpringRepository должен предоставляться Spring (насколько я понимаю), я немного растерялся и был бы признателен за любую помощь
Вот что я считаю соответствующими зависимостями
