public interface JobRepository extends JpaRepository<Job, Long>{

}

Вот мой репозиторий. Ошибка, которую я получаю, заключается в следующем. Это кажется довольно простой вещью, и я не уверен, как я мог облажаться.

Вот часть pojo, которую я пытаюсь сохранить 

    @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;

Я пытаюсь сделать это с как можно меньшим количеством xml. У меня есть ниже аннотации на мой основной класс 

@SpringBootApplication
@EnableCircuitBreaker
@ImportResource({"classpath*:/META-INF/**/spring-bootstrap.xml"})
@EnableJpaRepositories

Мой источник данных определен в xml, и я добавил фабрику диспетчера сущностей, пытаясь устранить неполадки, но не думал, что это необходимо.

Я понял. Мои enableJpaRepositories не ссылались на entityManagerFactory. 

@EnableJpaRepositories(basePackages="package name", entityManagerFactoryRef="entityManagerFactory")

Очень трудно найти правильный пример для всего, что связано с весной (или Java в этом отношении). Все TIMTOWTDI - убийца.

Пожалуйста, добавьте пакет репозитория в компонент entityManagerFactory 

<property name="packagesToScan" value="repository.package" />
