我有一个正确定义的弹簧配置XML文件，它导入一些其他XML文件。测试应该从MySQL数据库读取/写入/删除记录。我遇到了hibernate的问题 - 测试无法访问数据库，而hibernate会抛出异常：
Unknown service requested [org.hibernate.stat.spi.StatisticsImplementor];
nested exception is org.hibernate.service.UnknownServiceException:
Unknown service requested [org.hibernate.stat.spi.StatisticsImplementor]
这是我的测试类：
@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hibernate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"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd">
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<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bean XML中定义的值，因此配置正常。我想这些注释在某种程度上是错误的，但我不知道该修复什么，因为异常告诉我什么都没有。
这是异常堆栈跟踪：

如果这是一项服务，请在测试环境中定义bean JukeBox。
如果这是dao，那么请将entitymanager，transaction manager和session factory注入bean。
