在spring中加载junit hibernate测试的应用程序上下文

标签： spring hibernate junit applicationcontext

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。
