我们的项目刚刚决定从Spring 2.5.5迁移到Spring 3.0.4。在我的原始代码中，我进行了如下单元测试：将JUnit JPA测试从Spring 2.5.5迁移到Spring 3.0.4
public class RequisitionDaoTest extends AbstractJpaTests
{
public static String FAIL_MSG_UNEXPECTED_ERROR = "FAIL: Unexpected Error";
@PersistenceContext
private EntityManager em;
@PersistenceUnit
private EntityManagerFactory emf;
@Test
public void testSomething()
{
...
}
}这对Spring 2.5.5很有效。现在使用Spring 3.0.4，AbstractJpaTests类已被弃用。
问题是我似乎无法找到用来替换它的东西。我已经看到了这个节目使用一种叫做AbstractTransactionalJUnit4SpringContextTests几个职位，但是当我转换为使用它，我得到以下错误：
SEVERE: Caught exception while allowing TestExecutionListener [org.springframewor[email protected]4aec4aec] to prepare test instance [[email protected]] org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'RequsitionDaoTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests.setDataSource(javax.sql.DataSource); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [javax.sql.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

由于我使用JPA，我没有或不需要Spring的一个DataSource bean。
那么在新的Spring中是否有任何对AbstractJpaTests类的直接模拟，还是应该继续现在使用已弃用的类？
谢谢...

使用不推荐使用的类并不是什么坏事，它只是意味着现在有一种替代方法可以实现。 – skaffman 2010-10-08 15:03:34
@skaffman没错，但是当我们迁移时，我倾向于尝试并删除弃用的东西，因为我知道在某个时候它将被删除。 – Steve 2010-10-08 15:24:43
