Spring @Autowired failed with Hibernate

Question

When I was using Hibernate I had a configuration class like this:

@Configuration
@ComponentScan
public class HibernateConfiguration {

    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        return new LocalSessionFactoryBean();
    }
}

Then I want to make sure this configuration class works fine, so I wrote an unit test like below:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = HibernateConfiguration.class)
public class HibernateConfigurationTest {
    @Autowired
    private LocalSessionFactoryBean localSessionFactoryBean;

    @Test
    public void someTest(){
    }
}

Then Intellij keeps telling me this message, and it also fail the compile so it's not an Intellij bug:

Could not autowire. No beans of LocalSessionFactoryBean type found.

And after I changed the LocalSessionFactoryBean to SessionFactory it works fine.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = HibernateConfiguration.class)
public class HibernateConfigurationTest {
    @Autowired
    private SessionFactory localSessionFactoryBean;

    @Test
    public void someTest(){
    }
}

And below is the source code of LocalSessionFactoryBean :

public class LocalSessionFactoryBean extends HibernateExceptionTranslator
    implements FactoryBean<SessionFactory>, ResourceLoaderAware, InitializingBean, DisposableBean {
}

Below are some version information:

<properties>
    <springframework.version>4.0.6.RELEASE</springframework.version>
    <hibernate.version>4.3.6.Final</hibernate.version>
    <mysql.version>5.1.31</mysql.version>
    <joda-time.version>2.3</joda-time.version>
    <testng.version>6.9.4</testng.version>
    <mockito.version>1.10.19</mockito.version>
    <h2.version>1.4.187</h2.version>
    <dbunit.version>2.2</dbunit.version>
</properties>

So why Spring could not autowire when I was using LocalSessionFactoryBean ? I think I have some misunderstand about the type deduction of Spring bean, because in my opinion the method below @Bean in the configuration class will register a bean which type is LocalSessionFactoryBean , rather than SessionFactory , and then the autowired should works fine but it didn't. Can anyone please give me some learning material about that? I tried to search something like that and got very little useful result. With many thanks!

您需要注入SqlSessionFactory而不是SessionFactory。
