Spring MVC基于Java的配置无法看到类路径属性文件

我正在尝试将我的Web应用程序从基于XML的配置迁移到基于Java的配置 . 我在“\ src \ main \ resources \”目录下有属性文件 . 在XML配置中我有这样的bean：

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
        <list>
            <value>classpath:test.properties</value>
        </list>
    </property>
</bean>

它运作得很好 .

现在我切换到Java配置，所以我有：

@Configuration
@ComponentScan(basePackages = {"blah.blah.blah.*"})
@Import({MVCConfig.class, PersistenceConfig.class, SecurityConfig.class})
@PropertySource("classpath:test.properties")
public class TestConfig {


}

但不幸的是我得到了例外：

我试过使用@PropertySource（“classpath *：test.properties”），然后将异常更改为：

引起：org.springframework.beans.factory.BeanDefinitionStoreException：无法加载bean类：blah.blah.blah.TestConfig;嵌套异常是java.io.FileNotFoundException：无法打开类路径资源[classpath *：test.properties]，因为它不存在...

领先的斜线也无济于事......

我的测试类开始如下：

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = TestConfig.class, loader = AnnotationConfigContextLoader.class)
public class IntegrationTests {

我究竟做错了什么？
