没有找到[密钥类]的[ManagedType]

我正在使用JPA，H2，EclipseLink，Java Config（no xml）。我的问题是，我得到这个没有[ManagedType]被发现的密钥类错误下面。它建议将<exclude-unlisted-classes>false</exclude-unlisted-classes>添加到我的persistence.xml，但我没有使用xml进行配置，所以我不知道如何解决它。没有找到[密钥类]的[ManagedType]

这是我的@Configuration课的摘录。

@ComponentScan(
     basePackages = { "com.foo.*"}, 
     excludeFilters = @Filter(type = FilterType.ANNOTATION, 
     value = Configuration.class)) 
@Configuration 
@EnableJpaRepositories(basePackages = "com.foo.data.repository") 
public class SeleniumAppTestConfig implements InitializingBean { 

    @Bean 
    public DataSource dataSource() { 
     EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder(); 
     return builder.setType(EmbeddedDatabaseType.H2) 
      .addScript("SeleniumCreateScript.sql").build(); 
    } 

    @Bean 
    public Properties jpaProperties() { 
     Properties props = new Properties(); 
     props.setProperty("eclipselink.ddl-generation", "create-tables"); 
     props.setProperty("eclipselink.weaving", "false"); 
     props.setProperty("eclipselink.logging.level", "FINEST"); 
     props.setProperty("eclipselink.logging.parameters", "true"); 
     return props; 
    } 

    @Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
     final PersistenceProvider persistenceProvider = new PersistenceProvider(); 

     final EclipseLinkJpaVendorAdapter vendorAdapter = 
      new EclipseLinkJpaVendorAdapter(); 
     vendorAdapter.setGenerateDdl(true); 
     vendorAdapter.setShowSql(true); 
     vendorAdapter.setDatabase(Database.H2); 

     LocalContainerEntityManagerFactoryBean emf = 
      new LocalContainerEntityManagerFactoryBean(); 
     emf.setDataSource(dataSource()); 
     emf.setPackagesToScan("com.foo.data.model"); 
     emf.setLoadTimeWeaver(new SimpleLoadTimeWeaver()); 
     emf.setPersistenceProvider(persistenceProvider); 
     emf.setPersistenceUnitName("SeleniumTests"); 
     emf.setJpaVendorAdapter(vendorAdapter); 
     emf.setJpaProperties(jpaProperties()); 
     emf.afterPropertiesSet(); 
     return emf; 
    } 

    @Bean 
    public PlatformTransactionManager transactionManager(){ 
     JpaTransactionManager transactionManager = new JpaTransactionManager(); 
     transactionManager.setEntityManagerFactory(
      entityManagerFactory().getObject()); 

     return transactionManager; 
    } 

    @Bean 
    public EclipseLinkJpaDialect exceptionTranslator() { 
     return new EclipseLinkJpaDialect(); 
    } 

}

这里是我的实体类（在com.foo.data.model package）：

@Entity 
@Table(name = "USER", schema = "SELENIUM") 
public class User { 
    @Id 
    @Column (name = "USERNAME") 
    private String username; 
    @Column (name = "PASSWORD") 
    private String password; 

    public String getUsername() { 
     return username; 
    } 
    public void setUsername(String username) { 
     this.username = username; 
    } 
    public String getPassword() { 
     return password; 
    } 
    public void setPassword(String password) { 
     this.password = password; 
    } 

    @Override 
    public String toString() { 
     return String.format(
      "User[username=%s, password='%s']", 
      username, password); 
    } 

}

这里是我的仓库：

@Repository 
public interface UserRepository extends CrudRepository <User, String> { 
    List<User> findByLastUsername(String username); 
}

最后，这里是我的测试：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = SeleniumAppTestConfig.class) 
public class RepositoryTest { 

    /** Logger for this class. */ 
    private static final Logger LOG = 
     Logger.getLogger(RepositoryTest.class); 

    @Autowired 
    private UserRepository userRepository; 

    @Test 
    public void testThings() { 
     final Iterable<User> users = userRepository.findAll(); 
     for (User user: users) { 
     LOG.info("user [" + user + "]."); 
     } 
    } 
}
