spring-data：不是托管类型：类java.lang.Object
我昨天开始使用spring-data项目，并试图将测试添加到我创建的存储库中。
项目结构看起来像
persistence/pom.xml src/main/java/ ApplicationConfig BaseRepository Network src/main/test/BaseRepositoryTest
ApplicationConfig看起来像
@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; } }
BaseRepository看起来像
import org.springframework.data.repository.Repository; public interface BaseRepository extends Repository { List findAll(); }
Network是一个实体类看起来像
@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; ... }
和BaseRepositoryTest看起来像
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 baseRepository; @Test public void testAllNetworks() { final List networks = baseRepository.findAll(); assertTrue(networks.isEmpty()); } }
我的pom.xml看起来像
org.springframework spring-core org.hibernate.javax.persistence hibernate-jpa-2.0-api 1.0.1.Final org.hibernate hibernate-entitymanager 4.3.5.Final org.springframework.data spring-data-jpa 1.6.0.RELEASE joda-time joda-time com.google.code.findbugs jsr305 org.springframework spring-test junit junit test com.h2database h2
当我运行mvn clean install ，我看到错误为

请帮助我确定我在这里做错了什么，我是这个项目的新手
存储库管理的类型必须在引导时知道，这意味着您需要实际创建一个具体的存储库，如下所示：
interface NetworkRepository extends BaseRepository { … }
您展示的代码中还有一些其他故障：
-
Network类没有任何使用@Id注释的属性 -
BaseRepository应该带有@NoRepositoryBean注释，以指示它根本不应该被实例化。 有关详细信息，请参阅参考文档
如果您有一个扩展另一个的存储库接口并且您忘记了超级接口上的@NoRepositoryBean，也会发生这种情况。
我遇到了同样的问题，并通过添加@NoRepositoryBean来解决
@NoRepositoryBean public interface BaseRespository extends PagingAndSortingRepository {}
由于my.package名称错误，我得到了同样的错误。 一旦我提供了正确的包装名称，它就可以正常使用。
@EnableJpaRepositories（’ my.package ‘）
请尝试以下更改
@ContextConfiguration(classes = {ApplicationConfig.class, BaseRepository.class}, loader=AnnotationConfigContextLoader.class)
我在做下面的错误：
在创建工厂时，我已经通过了repo包而不是实体包。
