屬性sessionFactory是必需的使用Spring Java配置內部類

我正在使用Spring 4的純Java配置（沒有web.xml），但有內部配置類的一些問題。我有多個配置文件春天這樣一個屬性sessionFactory是必需的使用Spring Java配置內部類

@Profile("dev") 
public @interface Dev {}

所以我DataSourceConfig內，我想對每個春天配置文件的多個@Configuration。喜歡的東西（假設DataSourceSetup標註有@Configuration接口）

@Configuration 
public class DataSourceConfig { 

    ... // some common methods to both @Dev & @Prod 

    @Dev 
    public static class DataSourceDev implements DataSourceSetup { 

     @Bean 
     @Override 
     public DataSource dataSource { 
      ... 
     } 

     @Bean 
     @Override 
     public LocalSessionFactoryBean sessionFactory() { 
      ... 
     } 

     ... 

    } 

    @Prod 
    public static classs DataSourceProd implements ... { 
     ... 
    } 

    ... 

}

有了這個，我可以只引用我的單元測試一個DataSourceConfig.class和改變
@ActiveProfiles({"dev"})。然而，當我運行測試，我得到一個

IllegalArgumentException: Property 'sessionFactory' is required.

完全跟蹤：

但它定義！不知道我錯過了什麼。這是我的Dao和使用sessionFactory的實現。

@Repository 
@Transactional(readOnly = true) 
public class EmployeeService implements EmployeeDao { 

    @Resource 
    private SessionFactory sessionFactory; 

    ... 
}

下面是從我WebAppInitializer

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected String[] getServletMappings() { 
     return new String[] { "/" }; 
    } 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class<?>[] { ApplicationConfig.class, DataSourceConfig.class, WebSecurityConfig.class }; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return new Class<?>[] { WebMvcConfig.class }; 
    } 

    ... 
}

的摘錄這是我的測試類

@RunWith(SpringJUnit4ClassRunner.class) 
@WebAppConfiguration 
@ContextConfiguration(classes = { ApplicationConfig.class, DataSourceConfig.class, WebSecurityConfig.class, 
    WebMvcConfig.class }) 
@ActiveProfiles({ "dev" }) 
public class HomeControllerTest { 

    @Autowired 
    private WebApplicationContext wac; 

    private MockMvc mockMvc; 

    @Before 
    public void setup() { 
     mockMvc = standaloneSetup(new HomeController()).build(); 
    } 

    @Test 
    public void testGetHomePage() throws Exception { 
     mockMvc.perform(get("/")).andExpect(status().isOk()); 
    } 

}

請發佈完整的堆棧跟蹤。另外，告訴我們你如何運行你的測試，不要告訴我們。 –

我想我想通了。在我的Config接口中註釋@Controller存在一些問題。所以我不需要對接口進行註釋，而需要對實現類進行註釋。例如我的DataConfigClass：

@Configuration 
public class DataSourceConfig { 

    ... // some common methods to both @Dev & @Prod 

    @Configuration 
    @Dev 
    public static class DataSourceDev implements DataSourceSetup { 

     @Bean 
     @Override 
     public DataSource dataSource { 
      ... 
     } 

     @Bean 
     @Override 
     public LocalSessionFactoryBean sessionFactory() { 
      ... 
     } 

     ... 

    } 

    @Configuration 
    @Prod 
    public static classs DataSourceProd implements ... { 
     ... 
    } 

    ... 

}

對我來說這似乎很奇怪。但是，哦，SessionFactory現在正在工作。

我不知道，但可能是問題是因爲在會話工廠的類型DataSourceConfig類..
