xml configuration of integration test with spring data mongo

1. junit test like below

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/spring/test-mongo-setup.xml"})
public class AlarmLogDataHandlerTest extends AbstractDbDataTest {

    @Autowired
    private AlarmRepository alarmRepository;
    @Autowired
    private AlarmDetailsRepository alarmDetailsRepository;
    private AlarmErrorDataHandler handler;
    private String inverterId = "inverter1";

    @Before
    public void init() {
        setCurrentMillisSystem();
        handler = new AlarmErrorDataHandler();
        ReflectionTestUtils.setField(handler, "alarmRepository", alarmRepository);
    }

    @After
    public void cleanData() {
        setCurrentMillisSystem();
        alarmRepository.deleteAll();
        alarmDetailsRepository.deleteAll();
    }

    @Test
    public void whenAlarmIsNewThenSaveAlarmLogsAndAlarmDetails() {
        // given
        String errorType = ErrorCode.L1.getErrorType();
        int errorCodeL1_value1 = 2;
        AlarmLogs logs = buildFullAlarmLogs(errorType, errorCodeL1_value1);

        // when
        handler.saveAlarmLogs(logs);

        // then
        Iterable<AlarmLogs> logsList = alarmRepository.findAll();
        assertThat(logsList.iterator().hasNext(), equalTo(true));
        AlarmLogs dbLogs = logsList.iterator().next();
        assertThat(dbLogs.getVersion(), equalTo(0L));
        assertThat(dbLogs.getErrorType(), equalTo(errorType));
        assertThat(dbLogs.getErrorValue(), equalTo(errorCodeL1_value1));
        assertThat(dbLogs.getAlarmDetails(), notNullValue());

        Iterable<AlarmDetails> alarmDetails = alarmDetailsRepository.findAll();
        assertThat(Lists.newArrayList(alarmDetails), hasSize(1));
    }
}
