我們的項目剛剛決定從Spring 2.5.5遷移到Spring 3.0.4。在我的原始代碼中，我進行了如下單元測試：將JUnit JPA測試從Spring 2.5.5遷移到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()
{
...
}
}這對Spring 2.5.5很有效。現在使用Spring 3.0.4，AbstractJpaTests類已被棄用。
問題是我似乎無法找到用來替換它的東西。我已經看到了這個節目使用一種叫做AbstractTransactionalJUnit4SpringContextTests幾個職位，但是當我轉換爲使用它，我得到以下錯誤：
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.

由於我使用JPA，我沒有或不需要Spring的一個DataSource bean。
那麼在新的Spring中是否有任何對AbstractJpaTests類的直接模擬，還是應該繼續現在使用已棄用的類？
謝謝...

使用不推薦使用的類並不是什麼壞事，它只是意味着現在有一種替代方法可以實現。 – skaffman 2010-10-08 15:03:34
@skaffman沒錯，但是當我們遷移時，我傾向於嘗試並刪除棄用的東西，因爲我知道在某個時候它將被刪除。 – Steve 2010-10-08 15:24:43
