Java 在测试中使用@SpringApplicationConfiguration会引发异常？

我正在尝试执行DAO测试，因此我希望Spring Boot构建实现，因此我进行了以下测试：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = FakeServiceRunner.class)
public class ClientDAOTests {

    @Autowired
    private ClientDAO dao;

    @Test
    public void testFindAllClients() {
        ....
        Page<Client> clients = this.dao.findAll(new PageRequest(0, 30, null));
        // Asserts..
    }
}

以及我的服务配置：

    @Configuration
    @Import({PersistenceConfiguration.class, TransformersConfiguration.class})
    public class ServicesConfiguration {

        @Autowired
        private ClientDAO clientDAO; //Comes from PersistenceConfiguration

        @Autowired
        @Qualifier("domainMapper")
        private MapperFacade mapper; //Comes from TransfomersConfiguration

        @Bean
        @Scope(BeanDefinition.SCOPE_PROTOTYPE)
        public ClientService clientService() {
            ClientServiceImpl clientService = new ClientServiceImpl(this.clientDAO);
            clientService.setMapper(this.mapper);
            return clientService;
        }

    }

最后，我的ClientServiceImpl类：

@Service
public class ClientServiceImpl
    implements ClientService {

    private static final Logger LOGGER = LoggerFactory.getLogger(ClientServiceImpl.class);

    private ClientDAO dao;
    private MapperFacade mapper;

    public ClientServiceImpl(ClientDAO dao) {
        this.dao = dao;
    }

    public void setMapper(MapperFacade mapper) {
        this.mapper = mapper;
    }

    // Service methods...
}

所以我将断点放在构造函数和clientService方法（ServicesConfiguration.class）中，并在调试中运行它，它没有加入这些断点中的任何一个

你知道发生了什么事吗？问候
