federdaten: Kein verwalteter Typ: Klasse Java.lang.Object

Ich habe gestern mit spring-data project angefangen und versuchte, das von mir erstellte Repository mit einem Test zu versehen.

Die Projektstruktur sieht so aus

persistence/pom.xml
           src/main/Java/
                        ApplicationConfig
                        BaseRepository
                        Network
           src/main/test/BaseRepositoryTest

Das ApplicationConfig sieht so aus

@Configuration
@ComponentScan
@EnableJpaRepositories
public class ApplicationConfig {
    @Bean
    public DataSource dataSource() {
        final EmbeddedDatabaseBuilder embeddedDatabaseBuilder = new EmbeddedDatabaseBuilder();
        embeddedDatabaseBuilder.setType(EmbeddedDatabaseType.H2);
        return embeddedDatabaseBuilder.build();
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        final HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
        jpaVendorAdapter.setDatabase(Database.H2);
        jpaVendorAdapter.setGenerateDdl(true);

        final LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
        localContainerEntityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter);
        localContainerEntityManagerFactoryBean.setPackagesToScan(getClass().getPackage().getName());
        localContainerEntityManagerFactoryBean.setDataSource(dataSource());

        return localContainerEntityManagerFactoryBean;
    }
}

Das BaseRepository sieht so aus

import org.springframework.data.repository.Repository;

public interface BaseRepository<T, ID extends Serializable> extends Repository<T, ID> {
    List<T> findAll();
}

Die Network ist wie eine Entity-Klasse

@Entity
public class Network extends com.org.comma.persistence.Entity {
    private final long networkId;

    private final String name;

    private final boolean active;

    private final DateTime createdAt;

    private String createdBy;

    private DateTime updatedAt;

    private String updatedBy;
...
}

und BaseRepositoryTest sieht aus wie

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {ApplicationConfig.class, BaseRepository.class})
public class BaseRepositoryTest {

    @Autowired
    BaseRepository<Network, Long> baseRepository;

    @Test
    public void testAllNetworks() {
        final List<Network> networks = baseRepository.findAll();
        assertTrue(networks.isEmpty());
    }
}

Mein pom.xml sieht so aus

        <artifactId>spring-core</artifactId>

    </dependency>
</dependencies>

Wenn ich mvn clean install starte, sehe ich einen Fehler als

Bitte helfen Sie mir herauszufinden, was ich hier falsch mache. Ich bin neu in diesem Projekt
