我尝试将junit测试写入我的服务。我在我的项目spring-boot 1.5.1中使用。一切正常，但是当我尝试自动装配bean（在AppConfig.class中创建）时，它给了我NullPointerException。我已经尝试了几乎所有东西。
这是我的配置类：
@Configuration
public class AppConfig {
@Bean
public DozerBeanMapper mapper(){
DozerBeanMapper mapper = new DozerBeanMapper();
mapper.setCustomFieldMapper(new CustomMapper());
return mapper;
}
}
和我的测试班：
@SpringBootTest
public class LottoClientServiceImplTest {
@Mock
SoapServiceBindingStub soapServiceBindingStub;
@Mock
LottoClient lottoClient;
@InjectMocks
LottoClientServiceImpl lottoClientService;
@Autowired
DozerBeanMapper mapper;
@Before
public void setUp() throws Exception {
initMocks(this);
when(lottoClient.soapService()).thenReturn(soapServiceBindingStub);
}
@Test
public void getLastResults() throws Exception {
RespLastWyniki expected = Fake.generateFakeLastWynikiResponse();
when(lottoClient.soapService().getLastWyniki(anyString())).thenReturn(expected);
LastResults actual = lottoClientService.getLastResults();
有人可以告诉我怎么了吗？
错误日志：
java.lang.NullPointerException
at pl.lotto.service.LottoClientServiceImpl.getLastResults(LottoClientServiceImpl.java:26)
at pl.lotto.service.LottoClientServiceImplTest.getLastResults(LottoClientServiceImplTest.java:45)
这是我的服务：
@Service
public class LottoClientServiceImpl implements …
