我有一个运行良好的 spring boot 2.0.0 M2 应用程序。

我在构造函数上使用自动装配

@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);
    }
    ...
}

当我尝试运行基本测试时

@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);

    }
}

我收到这个错误

org.springframework.beans.factory.UnsatisfiedDependencyException：创建名称为“com.sonos.arcor.service.AddressServiceTest”的bean时出错：通过字段“服务”表示不满足的依赖关系；嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有“com.sonos.arcor.service.AddressService”类型的合格 bean 可用：预计至少有 1 个有资格作为自动装配候选者的 bean。依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true)}

我不明白为什么我会收到这个错误。

您需要注释测试，SpringBootTest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
}

你也不需要MockitoAnnotations.initMocks(this);

Spring 负责模拟处理

当 [@MockBean is] 在字段上使用时，创建的模拟实例也将被注入。模拟 bean 在每个测试方法后自动重置

请参阅模拟和间谍 bean
