我有以下测试课：

@ActiveProfiles({ "DataTC", "test" })
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {BaseTestConfiguration.class, DataTestConfiguration.class, JpaConfiguration.class, PropertyPlaceholderConfiguration.class })
public class RegularDayToTimeSlotsTest {
...

问题似乎来自BaseTestConfiguration类：

@Configuration
@ComponentScan(basePackages = { "com.bignibou" }, excludeFilters = { @Filter(type = FilterType.CUSTOM, value = RooRegexFilter.class),
        @Filter(type = FilterType.ANNOTATION, value = Controller.class), @Filter(type = FilterType.ANNOTATION, value = ControllerAdvice.class) })
public class BaseTestConfiguration {

}

我系统地得到了这个异常：

我不确定如何解决此问题。当我运行测试时，Spring不知何故正在寻找ServletContext并收到上述异常…
