将ehcache添加到DAO类后，Junit测试失败，无法在测试类中实例化DAO

我正在为我的项目添加ehcache，我有一个单元测试类，我的DAO运行正常，如果我在DAO上注释ehcache注释，如果我取消注释它就会失败，说它不能自动装入DAO bean .

这是我得到的错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.nicobrest.kamehouse.dao.DragonBallUserDaoJpaTest': Injection of autowired dependencies failed;
nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.nicobrest.kamehouse.dao.DragonBallUserDaoJpa com.nicobrest.kamehouse.dao.DragonBallUserDaoJpaTest.dragonBallUserDaoJpa;
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.nicobrest.kamehouse.dao.DragonBallUserDaoJpa] found for dependency:
expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=dragonBallUserDaoJpa)}

我也试过，而不是在单元测试中自动装配DAO bean，自动装配应用程序上下文并按名称获取bean，当我这样做时，我得到一个异常，它不能将$ proxy32转换为我的DAO类 .

    e.printStackTrace();
    fail("Caught unexpected exception.");
  }

  EntityManager em = getEntityManager();
  try {
    em.getTransaction().begin();
    em.persist(dragonBallUser);
    em.getTransaction().commit();
  } catch (PersistenceException pe) {
    ...
  } finally {
    em.close();
  }
  return dragonBallUser.getId();
}

我不知道还有什么可以尝试，任何想法？

我正在使用Spring 4.2.4.RELEASE，Hibernate 5.1.0.Final，Hibernate JPA 1.0.0.Final，ehcache 2.9.0，JUnit 4.12 .

这肯定是与ehcache相关的东西，因为注释注释使得在测试类中自动装配DAO成为可能，并且单元测试通过但我尝试了几个小时并且无法弄明白 .

谢谢！
