我用JUnit测试以下DAO:

@Repository
public class MyDao {

    @Autowired
    private SessionFactory sessionFactory;

    // Other stuff here

}

如您所见,sessionFactory使用Spring自动装配.当我运行测试时,sessionFactory保持为null并且我得到一个空指针异常.

这是Spring中的sessionFactory配置:

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation">
        <value>classpath:hibernate.cfg.xml</value>
    </property>
    <property name="configurationClass">
        <value>org.hibernate.cfg.AnnotationConfiguration</value>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${jdbc.dialect}</prop>
            <prop key="hibernate.show_sql">true</prop>
        </props>
    </property>
</bean>

怎么了？如何为单元测试启用自动装配？

更新:我不知道它是否是运行JUnit测试的唯一方法,但请注意我在Eclipse中运行它,右键单击测试文件并选择"run as" - >"JUnit test"

我的WEB-INF目录下有一些XML文件:

• lyricsBaseApp-servlet.xml中
• hibernate.xml
• dataSource.xml
• beans.xml中

servlet xml导入其他xml文件:

<import resource="dataSource.xml"/>
<import resource="hibernate.xml"/>
<import resource="beans.xml"/>

我希望我的junit4 JukeboxTest类包含整个弹簧配置.使用默认文件名我创建了一个JukeboxTest-content.xml文件.最后,我不知道该放什么......

我试过了:

<import resource="/WEB-INF/dataSource.xml"/>
<import resource="/WEB-INF/hibernate.xml"/>
<import resource="/WEB-INF/beans.xml"/>

要么

<import resource="classpath:./WEB-INF/dataSource.xml"/>
<import resource="classpath:./WEB-INF/hibernate.xml"/>
<import resource="classpath:./WEB-INF/beans.xml"/>

和其他一些想法,但都失败了.有人能指出我如何访问这些文件以及spring解释这些文件路径的方式是什么？

我正在尝试运行 mvnintegration-test阶段，但在执行集成测试时出现Failed to load ApplicationContext错误（单元测试正确执行）。我正在SpringJUnit4ClassRunner使用类来运行我的测试。

这是完整的堆栈跟踪：
