将弹簧上下文移动到META-INF后，自动装配失败

Question

将我的spring上下文配置移动到src/main/resources/META-INF/spring后，我无法连接我的bean。在我的spring上下文直接放在src文件夹之前，我的测试以及自动装配运行良好：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:cmn-dao-context.xml" })
@Transactional
public class ComplaintDaoTest extends TestCase {

    @Autowired
    private ComplaintDao mComplaintDao;

错误：

09.12.2013 23:30:02 org.springframework.test.context.TestContextManager prepareTestInstance
SCHWERWIEGEND: Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@873723] to prepare test instance [null(de.bc.qz.dao.ComplaintDaoTest)]

database.properties：

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location">
        <value>database.properties</value>
    </property>
</bean>

有人能帮助我吗？

Answer 1

尝试使用classpath*:META-INF/spring/cmn-dao-context.xml

修改

<bean
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location">
        <value>META-INF/spring/database.properties</value>
    </property>
</bean>
