Spring: Trouble wiring up a datasource in a Junit test

I'm using Spring 3.1.0.M2. I'm writing some JUnit 4 tests to test some database functionality, but I'm having trouble wiring up my datasource. In my JUnit class, I have …

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class, 
    classes={DataSource.class, WebLeadsDAOImpl.class})
public class TestDB {
...
@Qualifier("mycoSessionFactory")
private SessionFactory sessionFactory;

/**
 * Using a single lead lookup should speed up our testing queries.
 * <p>
 * The lead is is 8104051
 * </p>
 */
@Before
public void prep() { 
    assertNotNull(sessionFactory);
    ...
}

but the "sessionFactory" object is repeatedly null. Here is how I'm trying to configure it …

@Lazy
@Component
@PropertySource("classpath:oracle.properties")
public class DataSource {
…

@Bean(name="mycoSessionFactory")
public SessionFactory sessionFactory() throws Exception {
   final SessionFactory sessionFactory = new AnnotationSessionFactoryBuilder()
        .setDataSource(dataSource()开发者_运维问答)
        .setHibernateProperties(databaseProperties())
        .setPackagesToScan("com.criticalmass.systems.leadsmonitor.domain")
        .setSchemaUpdate(false)
        .buildSessionFactory();
   return sessionFactory;
}

The reason I don't just use "@Autowired" is because I have two SessionFactory beans. Any ideas why my datasource isn't wiring up correctly? Thanks, - Dave

Thanks for your updated suggestion, but the answer turns out to be I had forgotten to add

@Autowired

before the member field. When I did that, everything worked great. -

Looks like you missed to annotate your test class by @ContextConfiguration.

I guess I have it: you missed the annotation that triggers Spring to inject something. Just add:

• @Inject or,
• @Resource or,
• @Autowired

to the variable declaration of sessionFactory in your test case.
