Java Spring 3.2+；Hibernate 4.3.4+；jUnit:EntityManagerFactory已关闭

我正在为我的Spring3.2.8+Hibernate4.3.4应用程序编写一些junit测试。我的测试类带有以下注释：

@DirtiesContext(classMode=ClassMode.AFTER_EACH_TEST_METHOD)
@Transactional
public class UserServiceImplTest {
   ...
   ...
}

但是，尝试使用实体管理器的方面引发了以下错误：

org.springframework.dao.InvalidDataAccessApiUsageException: EntityManagerFactory is closed; nested exception is java.lang.IllegalStateException: EntityManagerFactory is closed

如果我查看日志，我会在第二次测试开始时看到以下错误消息：

2014-04-02 16:36:48,891 [main] WARN  org.hibernate.jpa.internal.EntityManagerFactoryRegistry - HHH000436: Entity manager factory name (default) is already registered.  If entity manager will be clustered or passivated, specify a unique value for property 'hibernate.ejb.entitymanager_factory_name'

我意识到这只是一个警告，但我想知道这是否是问题的一部分。我不明白为什么它抱怨工厂已经注册，而

@DirtiesContext

应该确保在开始第二次测试之前清除上下文

在我的第一次测试结束时，我确实看到上下文正在被清理：

所以我不知道为什么它会抱怨EntityManagerFactory已经注册了。此外，我不确定当我试图访问EMF时为什么它是关闭的

---

我是否需要做一些特殊的事情来确保在每次测试中仍然可以访问它？我确实发现这与问题有关，但这并不能帮助我确定发生这种情况的原因。

似乎有人试图在设置spring上下文之前或在处理它之后获取持久性上下文

---

您是否有一些junit@before或@after注释的方法来访问持久性？

经过大量调试后，发现问题出在使用EntityManagerFactory的方面。假设方面是在Spring上下文之外实例化的，当上下文刷新时，方面的引用不会更新。因此，方面保存了一个对一个确实已关闭的EMF的引用——第一个单元测试中的原始EMF。现在我只需要弄清楚如何让Spring在更新上下文时更新/刷新引用。

否-在

@before

或

@after

方法中没有任何内容。但是经过一系列的调试，我终于意识到这是我的方面的问题；它从第一个上下文中维护EntityManagerFactory bean引用，在上下文刷新后不更新引用。@Gab-我会的，但我需要2天才能接受自己的答案。：）你能想出一种刷新方面引用的方法吗？@AnkitBatra这是几年前的事了，所以我记不清了，但我确实记得，当我不想让方面保留上下文信息时，我很难让它们保留上下文信息。我努力解决这个问题，但是有很多静态数据是在方面初始化的（由于AJ的工作方式），我无法“撤销”。我相信我唯一能绕过这个问题的方法就是启动多个fork，每个测试都在一个独立的fork中运行。@Eric感谢您回来。
