如何在使用JUNIT的DAO測試中使用依賴注入？

我正在使用Hibernate和Spring。 Mys DAO正在我的應用程序中工作。我需要現在創建測試，但我遇到了問題。如何在使用JUNIT的DAO測試中使用依賴注入？

這是我的課測試：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations={"classpath:applicationContext-test.xml"}) 
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class}) 
public class MunicipioDaoTest { 

    @Autowired 
    private MunicipioDAO municipioDAO; 

    @Test 
    public void testCount() { 
     ...  
     municipioDAO.count(); 
     ... 
    } 

    @Test 
    public void testGet() { 
     ... 
     municipioDAO.get(1); 
     ... 
    }

的testCount（）的作品，但testGet（）我得到這個異常：

這裏有什麼問題？

Spring運行正常，DAO正在注入測試。

錯誤Unknown entity: com.eagle.eagleservice.model.entity.Municipio是由於Hibernate無法找到DAO正在使用的Municipo類。

貌似的sessionFactory豆不掃描包com.eagle.eagleservice.model.entity該Municipio實體是英寸

在sesionFactory豆，更改

<property name="packagesToScan" value="com.eagle.core.model, com.eagle.eagleservice.model" />

要包括com.eagle.eagleservice.model.entity

<property name="packagesToScan" value="com.eagle.core.model, com.eagle.eagleservice.model, com.eagle.eagleservice.model.entity" />

我試過了，但沒有奏效。我犯了同樣的錯誤。 –

的packagesToScan不包含實體類所在的包：com.eagle.eagleservice.model.entity。
