Proper way to autowire a Hibernate Session in a Spring Transaction JUnit test

This question is similar to a previous one. I am trying to @Autowire a Hibernate Session in one of my Spring-JUnit-Transactional tests but I am getting this exception:

java.lang.IllegalStateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional ...

Here is my JUnit class:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/applicationContext.xml"})
@TransactionConfiguration(transactionManager="transactionManager")
@Transactional
public class MyTest {
    @Qualifier("session")
    @Autowired
    private Session session;

    @Test
    public void testSomething() {
        session.get(User.class, "me@here.com");
    }
}

Every works fine if I @Autowire a SessionFactory and get my Session programmatically (instead of defining it in the Spring XML) like so:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/applicationContext.xml"})
@TransactionConfiguration(transactionManager="transactionManager")
@Transactional
public class MyTest{    
    @Qualifier("sessionFactory")
    @Autowired
    private SessionFactory sessionFactory;

    @Test
    public void testSomething() {
    Session session = SessionFactoryUtils.getSession(sessionFactory, false);
        session.get(User.class, "me@here.com");
    }
}

I can, however, get my original example to work if I define my Session in my Spring XML with <aop:scoped-proxy /> like so:

<?xml version="1.0" encoding="UTF-8"?>

<beans  xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
