Ошибка при создании bean-компонента с именем 'resourceHandlerMapping' [org / springframework / web / servlet / config / annotation / DelegatingWebMvcConfiguration.class]

Я пытаюсь запустить тест JUnit, но получаю эту ошибку. Я много пробовал, но не нашел решения. Были исключения. Я также попытался выполнить componentScan в тестовом классе :-@ComponentScan (basePackages = {"com.jitender.bookStore"}, excludeFilters = {@Filter (type = FilterType.ANNOTATION, classes = Configuration.class)}), но это тоже не сработало.
