使用以下语句时，我得到的Matchers无效使用异常。 Mockito.when（CrossSellOffersRetrievalService.isHourInInterval（Mockito.anyString（），Mockito.anyString（），Mockito.anyString（）））。thenReturn（true）;

如何避免这种异常？

class：

@Component
public class CrossSellOffersRetrievalService {

    @Autowired
    private CrossSellOffersRetrieval crossSellOffersRetrieval;

    public List<CrossSellOffer> getapplicableOffers(String channelId,String customerId,String cinSuffix,String countryCode,String interactionPoint,String sessionId,Integer numberOfOffers)throws CrossSellOffersException {

        if (isOnLineserverTime()) {
            if (numberOfOffers == null) {
                numberOfOffers = 1;
            }
            List<CrossSellOffer> crossSellOffersList = crossSellOffersRetrieval.getapplicableOffers(channelId,customerId,cinSuffix,countryCode,interactionPoint,sessionId,numberOfOffers);

                return crossSellOffersList;

        } else {
            throw new CrossSellOffersException(Constants.ERROR_CODE,Constants.WRONG_SERVER_TIME);
        }
    }

    public static boolean isHourInInterval(String target,String start,String end) {
        return ((target.compareTo(start) >= 0) && (target.compareTo(end) <= 0));
    }

    public boolean isOnLineserverTime() {

        String serverTime = DateTimeFormatter.ofPattern("HH.mm").format(LocalDateTime.now(ZoneId.of("Asia/Singapore")));

        boolean value = isHourInInterval(serverTime,"08.00","23.15");
        return value;
    }

}

Junit测试类：

@RunWith(MockitoJUnitRunner.class)
public class CrossSellOffersRetrievalServiceTest {

    @InjectMocks
    private CrossSellOffersRetrievalService crossSellOffersRetrievalService;

    @Mock
    private CrossSellOffersRetrieval crossSellOffersRetrieval;

    @Test
    public void getapplicableOffersTest() throws CrossSellOffersException {
        Mockito.when(CrossSellOffersRetrievalService.isHourInInterval(Mockito.anyString(),Mockito.anyString(),Mockito.anyString())).thenReturn(true);
        Mockito.when(crossSellOffersRetrieval.getapplicableOffers(Mockito.anyString(),1)).thenReturn(CrossSellOffersRetrievalHandlerTest.sampleCrossSellOffersList());
        List<CrossSellOffer> crossSellOffersList = crossSellOffersRetrievalService.getapplicableOffers("MBSG","S7754061Z","00","SG","NEW_CC_ADDON","IBOXS007",1);
    }
}

输出：

org.mockito.exceptions.misusing.InvalidUseOfmatchersException:

You cannot use argument matchers outside of verification or stubbing.
Examples of correct usage of argument matchers:
    when(mock.get(anyInt())).thenReturn(null);
    doThrow(new RuntimeException()).when(mock).someVoidMethod(anyObject());
    verify(mock).someMethod(contains("foo"))
