向所有存储库添加自定义行为 - 不起作用

Question

我使用Spring Data JPA，我正在尝试向所有存储库添加自定义行为，如下所述：http://static.springsource.org/spring-data/data-jpa/docs/current/reference/html/#repositories.custom-behaviour-for-all-repositories

请参阅下面的实施。

我的实体类：

@Entity
public class Car extends AbstractPersistable<Long> {

    private String model;
    private String manufaturer;

    public Car() {
        this.setId(null);
    }

    public Car(Long id) {
        this.setId(id);
    }

    public void setModel(String model) {
        this.model = model;
    }

    public void setManufaturer(String manufaturer) {
        this.manufaturer = manufaturer;
    }

    public String getModel() {
        return model;
    }

    public String getManufaturer() {
        return manufaturer;
    }
}

我的界面声明了自定义共享行为：

@NoRepositoryBean
public interface CommonRepository<T, ID extends Serializable> extends JpaRepository<T, ID> {
    String custom();
}

我的存储库基类 - 实现：

public class CommonRepositoryImpl<T, ID extends Serializable> extends SimpleJpaRepository<T, ID> implements CommonRepository<T, ID> {

    public CommonRepositoryImpl(Class<T> domainClass, EntityManager em) {
        super(domainClass, em);
    }

    public CommonRepositoryImpl(JpaEntityInformation<T, ?> entityInformation,
                                EntityManager entityManager) {
        super(entityInformation, entityManager);
    }

    @Override
    public String custom() {
        return "CustomValue";
    }

}

我的工厂豆：

public class CommonRepositoryFactoryBean<R extends JpaRepository<T, I>, T, I extends Serializable> extends
        JpaRepositoryFactoryBean<R, T, I> {

    @Override
    protected RepositoryFactorySupport createRepositoryFactory(EntityManager entityManager) {

        return new CustomRepositoryFactory(entityManager);
    }

    private static class CustomRepositoryFactory<T, I extends Serializable> extends JpaRepositoryFactory {

        private EntityManager entityManager;

        public CustomRepositoryFactory(EntityManager entityManager) {
            super(entityManager);

            this.entityManager = entityManager;
        }

        @Override
        protected Object getTargetRepository(RepositoryMetadata metadata) {

            return new CommonRepositoryImpl<T, I>((Class<T>) metadata.getDomainType(), entityManager);
        }

        @Override
        protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata) {

            // The RepositoryMetadata can be safely ignored, it is used by the JpaRepositoryFactory
            // to check for QueryDslJpaRepository's which is out of scope.
            return CommonRepositoryImpl.class;
        }
    }
}

我的java配置：

@EnableJpaRepositories( basePackageClasses = Car.class, repositoryFactoryBeanClass = CommonRepositoryFactoryBean.class)
@Configuration
class CommonRepositoryConfig {
}

最后我的存储库：

public interface CarRepository extends CommonRepository<Car, Long> {
}

我的简单单元测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = CommonRepositoryConfig.class)
public class CarRepositoryTests {

    @Autowired
    CarRepository repository;

    /**
     * Test invocation of custom method.
     */
    @Test
    public void testCustomMethod() {

        Car car = new Car();
        car.setManufaturer("ford");

        Car car1 = repository.save(car);

        String customCarValue = repository.custom();
        System.out.println(customCarValue);
        assertNotNull(customCarValue);

    }

}

但是当我运行我的unittest时，我收到了这个错误：

所有类都在同一个包中。

修改： 我添加了一个LocalContainerEntityManagerFactoryBean和其他bean，如下所述： http://spring.io/guides/tutorials/data/3/ 并得到以下错误。
