Question

我有一个Crud Repository界面

@Repository
public interface SampleRepository extends CrudRepository<Metadata, String> {
     findById(UUID id);
}

I am trying to use it in my test class which is in another package
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {TestConfig.class})
@WebAppConfiguration
public class SampleRepositoryTest {

    @Autowired
    private SampleRepository sampleRepository;

它说没有发现SampleRepository的bean定义。任何人都可以帮助我为什么我不能自动装载这个存储库

如评论中所述：SampleRepository不需要@Repository。 @WebAppConfiguration对测试也看起来很奇怪。但这两个都没问题。

更重要的是：即使您没有提供TestContext.java文件，它应该是这样的：

@Configuration
// be sure to provide base package where your repostories are located
@EnableJpaRepositories(basePackages = {
    "com.acme.repositories"
})
public class TestContext {
  // your datasource
  @Bean
  public DataSource dataSource() {
    EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
    return builder.setType(EmbeddedDatabaseType.HSQL).build();
  }

  // your entity manager factory
  @Bean
  public EntityManagerFactory entityManagerFactory() {

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setGenerateDdl(true);

    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter(vendorAdapter);
    // your domain classes package
    factory.setPackagesToScan("com.acme.domain");
    factory.setDataSource(dataSource());
    factory.afterPropertiesSet();

    return factory.getObject();
  }

  // your jpa transaction manager
  @Bean
  public PlatformTransactionManager transactionManager() {
    JpaTransactionManager txManager = new JpaTransactionManager();
    txManager.setEntityManagerFactory(entityManagerFactory());
    return txManager;
  }
}

Answer 2

没有必要使用@Repository。您的代码应为：

public interface SampleRepository extends CrudRepository<Metadata, String> {
 @Query(value = "select * from db.tabel where id = :id", nativeQuery = true)
 findById(@Param("id") UUID id);
 }

@Autowired找不到Repository bean
