스프링 테스트 컨텍스트 Autowired

Question

바보 같은 질문을 드려 죄송 합니다만,이 코드가 스프링과 작동하지 않는 이유를 알 수 없습니다. 클래스와

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(loader = AnnotationConfigContextLoader.class) 
public class DBDumpTest { 
    @Autowired 
    private DataSource source; 

    @Configuration 
    static class ContextConfiguration { 
     @Bean 
     public DataSource dataSource() { 
      return Mockito.mock(DataSource.class); 
     } 
    } 

    @Test 
    public void testDump() throws Exception { 
     Assert.assertNotNull(source); //OK 
     Assert.assertNotNull(new DBDump().getDatasource()); //NULL NOT OK 
    } 
} 

:

public class DBDump { 
    private static final Logger logger = LoggerFactory.getLogger(DBDump.class); 

    @Autowired 
    private DataSource datasource; 


    public DataSource getDatasource() { 
     return datasource; 
    } 
} 

왜 않는 새로운 DBDUMP() GetDataSource() 메소드를 테스트 클래스에 @Autowired 주석이 작동하는 것 같다 동안 조롱 인스턴스를 반환하지.?

Answer 1

좋아, 이제 Autowiring을 통해 만들어야한다는 것을 이해했습니다. 이게 옳은 거지?

@Component 
public class DBDump { 
    @Autowired 
    private DataSource datasource; 

    public DataSource getDatasource() { 
     return datasource; 
    } 
} 

하지만 난 그냥 예외 수 :

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(loader = AnnotationConfigContextLoader.class) 
public class DBDumpTest { 
    @Autowired 
    private DataSource source; 

    @Autowired 
    private DBDump classUnderTest; 

    @Configuration 
    static class ContextConfiguration { 
     @Bean 
     public DataSource dataSource() { 
      return Mockito.mock(DataSource.class); 
     } 
    } 

    @Test 
    public void testDump() throws Exception { 
     Assert.assertNotNull(source); //OK 
     Assert.assertNotNull(classUnderTest.getDatasource()); //NULL NOT OK 
    } 
} 

그리고 DBDUMP 클래스는 지금

@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = DBDump.class)

을 그때 내 contextConfiguration이를 추가하는 경우

또 다른 예외가 나타납니다.
