[AspectJ] Extension and Implementation

    declare parents: EmpDao extends GenericDao<Emp, EmpParams>;
    declare parents: EmpDaoImpl extends HibernateGenericDao<Emp, EmpParams>;
    declare @type: EmpDaoImpl: @org.springframework.stereotype.Repository;

EmpDao 클래스가 GenericDao 클래스를 상속 받도록 설정.
EmpDaoImpl 클래스가 HibernateGenericDao 클래스를 상속 받도록 설정.
EmpDaoImpl 클래스에 @Repository 애노테이션 추가.

문법이 복잡해 보였는데 막상 사용해보니 간단 간단 하네요.

public interface EmpDao {

}

public class EmpDaoImpl implements EmpDao {

}

이런 기초적인 코드만 존재하지만..

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/applicationContext.xml", "/applicationContext-datasource.xml"})
@Transactional
public class EmpDaoImplTest {

    @Autowired
    EmpDaoImpl daoImpl;

    @Test
    public void daoInterface() throws Exception {
        assertNotNull(daoImpl);
        daoImpl = new EmpDaoImpl();
        GenericDao<Emp, EmpParams> gdao = daoImpl;
        HibernateGenericDao<Emp, EmpParams> hgdao = daoImpl;
    }

    @Test
    public void crud() throws Exception {
        Emp emp = new Emp();
        daoImpl.add(emp);
        daoImpl.flush();
        assertEquals(1, daoImpl.getAll().size());
    }

}

이런 테스트를 돌릴 수 있다는거...
