Spring JPA Dao - フィールドをオートワイヤできませんでした。

Question

JPA設定をテストするためにJunitテストを設定しようとしています。クラスは以下の通りです：ここ

@ContextConfiguration 
@RunWith(SpringJUnit4ClassRunner.class) 
public class OrderPersistenceTests { 
    @Autowired 
    public JpaDaoRole dr; 

    @Transactional 
    public void test1() throws Exception { 
     Role r = new Role(); 
     r.setIdRole(18); 
     r.setDescription("description"); 
     dr.persist(r); 
     Role r1=dr.findById(r.getIdRole()); 
     assertEquals(r.getIdRole(), r1.getIdRole()); 
    } 
} 

も私のアプリコンテキストのコンフィギュレーションです：私は、エンティティ・クラスが正しくロードされているというのが私のログから、私が見る私のテストを起動しようとすると

が、 DAOクラスはautowiredできません。私のDAOの実装は次のとおりです。

@Repository 
public class JpaDaoRole extends JpaDao<Role, Integer> implements DaoRole { 

} 

---

public abstract class JpaDao <E, K> implements Dao<E, K> { 
    protected Class<E> entityClass; 

    private static final Logger logger = LoggerFactory.getLogger(JpaDao.class); 

    @PersistenceContext 
    protected EntityManager entityManager; 

    public JpaDao() { 
     ParameterizedType genericSuperclass = (ParameterizedType) getClass().getGenericSuperclass(); 
     this.entityClass = (Class<E>) genericSuperclass.getActualTypeArguments()[0]; 
     logger.info(this.entityClass.toString()); 
    } 

    public EntityManager name() { 
     return entityManager; 
    } 

    public void persist(E entity) { entityManager.persist(entity); } 

    public void remove(E entity) { entityManager.remove(entity); } 

    public E findById(K id) { return entityManager.find(entityClass, id); } 
} 

私は、次のstheログ：

私は@RepositoryとしてのCLA jpadaoを宣言した場合autowiredされていないので、私は理解することはできません。あなたの助けを事前に

おかげ

ダニーロ私はあなたが@ContextConfigurationとあなたのテストクラスに注釈を付けると、構成XMLが配置され、スプリング伝えるために持っていると信じています

Answer 1

をOrderPersistenceTestsでは、実際のクラスではなく、DaoRoleというインターフェイスを使用する必要があります。

@Autowired 
public DaoRole dr; 

Answer 2

：私は思う

@ContextConfiguration(locations = {"classpath:app-context.xml"}) 
@RunWith(SpringJUnit4ClassRunner.class) 
public class OrderPersistenceTests { 
    ... 
}
