我有一个正确定义的 spring 配置 XML 文件，它导入了一些其他的 XML 文件。测试应该从 MySQL 数据库中读取/写入/删除记录。我遇到了休眠问题 - 测试无法访问数据库并且休眠抛出以下异常：

Unknown service requested [org.hibernate.stat.spi.StatisticsImplementor];
nested exception is org.hibernate.service.UnknownServiceException:
Unknown service requested [org.hibernate.stat.spi.StatisticsImplementor]

这是我的测试课：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(value = "classpath:*.xml")
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
@Transactional
public class JukeboxTest {

    @Autowired
    private ApplicationContext applicationContext;

    private Jukebox jukebox;

    private SessionFactory sessionFactory;
    private Session session = null;

    @BeforeClass
    public static void setUpClass() {
    }

    @AfterClass
    public static void tearDownClass() {
    }

    @Before
    public void setUp() {
        jukebox = (Jukebox) applicationContext.getBean("metal_jukebox");
        sessionFactory = (SessionFactory) applicationContext.getBean("sessionFactory");
        session = sessionFactory.openSession();
        System.out.println(jukebox.getName());
    }

    @After
    public void tearDown() {
        session.close();
        sessionFactory.close();
    }

    @Test
    @Transactional
    public void testGetName() {
        assertEquals("Metal Jukebox", jukebox.getName());
    }

这是我的休眠配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
        <property name="annotatedClasses">
            <list>
                <value>com.blogspot.symfonyworld.lyricsbase.model.Song</value>
            </list>
        </property>
    </bean>

    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

system.out 行正确显示了 bean XML 中定义的值，所以配置没问题。我猜注释在某种程度上是错误的，但我不知道要修复什么，因为异常什么也没告诉我。

这是异常堆栈跟踪：

如果这是一个服务，请在测试上下文中定义 bean JukeBox。

如果这是 dao，那么请将实体管理器、事务管理器和会话工厂注入 bean。
