这个问题类似于以前的问题 一。我在尝试着 @Autowire
我的一个Spring-JUnit-Transactional测试中的Hibernate会话,但是我得到了这个异常:
java.lang.IllegalStateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional ...
这是我的JUnit类:
@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");
}
}
如果我,每一件工作都很好 @Autowire
一个 SessionFactory
得到我的 Session
以编程方式(而不是在Spring XML中定义它),如下所示:
@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");
}
}
但是,如果我定义我的话,我可以得到我原来的例子 Session
在我的Spring XML中 <aop:scoped-proxy />
像这样:

我的问题是:为什么 <aop:scoped-proxy />
鉴于我的单元测试中应该只有一个线程限制的事务上下文?什么 是 定义我的正确方法 Hibernate Session
豆?
