测试期间不满足的依赖项

Question

@RequestMapping(value = "/rest")
@RestController
public class AddressRestController extends BaseController{

    private final AddressService AddressService;

    @Autowired
    public AddressRestController(final AddressService AddressService) {
        this.AddressService = AddressService;
    }
    ...
}

@Service
public class AddressServiceImpl extends BaseService implements AddressService {

    @Autowired
    public AddressServiceImpl(final AddressRepository AddressRepository) {
        this.AddressRepository = AddressRepository;
    }

    private final AddressRepository AddressRepository;
    ...
}


public interface AddressRepository extends JpaRepository<Address, Integer>, AddressRepositoryCustom {

}

@Repository
public class AddressRepositoryImpl extends SimpleJpaRepository implements AddressRepositoryCustom {
    @PersistenceContext
    private EntityManager em;

    @Autowired
    public AddressRepositoryImpl(EntityManager em) {
        super(Address.class, em);
    }
    ...
}

@RunWith(SpringJUnit4ClassRunner.class)
public class AddressServiceTest {

    @Autowired
    private AddressService service;

    @MockBean
    private AddressRepository restTemplate; 

    @Test
    public void getAddress(){

        MockitoAnnotations.initMocks(this);

        Pageable page = PageRequest.of(0, 20);

        Page<Address> pageAdr = mock(Page.class);

        given(this.restTemplate.findAll(page)).willReturn(pageAdr);

        Page<AddressDto> pageDto = service.getAddress(page);

    }
}

org.springframework.beans.factory.unsatisfiedDependencyException：创建名为“com.sonos.arcor.service.AddressServiceTest”的bean时出错：通过字段“service”表示的未满足的依赖项；嵌套异常为org.springframework.beans.factory.noSuchBeanDefinitionException：没有“com.sonos.arcor.service.AddressService”类型的合格bean可用：应至少有一个合格的自动候选bean。依赖项注释：{@org.SpringFramework.Beans.Factory.Annotation.AutoWired(required=true)}

我不明白为什么我会犯这个错误。

您需要使用springboottest注释测试，以便spring初始化应用程序上下文

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html#boot-features-testing-spring-boot-applications

@SpringBootTest
@RunWith(SpringJUnit4ClassRunner.class)
public class AddressServiceTest {
// the remaining test
}

您也不需要mockitoannotations.initmocks(this)；

Spring负责模拟处理

当在字段上使用[@mockbean]时，创建的mock的实例也将被注入。每个测试方法后都会自动重置模拟bean
