SpringBoot @WebMvcTest和@MockBean无法正常工作
似乎@WebMvcTest
并@MockBean
没有按预期工作。也许我缺少了一些东西…我有一个带有某些依赖关系的控制器@MockBean
,但是我的应用程序无法启动,因为它找不到另一个我认为在这种情况下不需要的bean。
控制器:
@RestControllerpublic class ExchangeRateStoreController {
private AddExchangeRate addExchangeRate;
private AddExchangeRateRequestAdapter addExchangeRateRequestAdapter;
private GetExchangeRate getExchangeRate;
private GetExchangeRateRequestAdapter getExchangeRateRequestAdapter;
@Autowired
public ExchangeRateStoreController(ExchangeRateRepository exchangeRateRepository, ExchangeRateDateValidator exchangeRateDateValidator, ExchangeRateView exchangeRateView) {
addExchangeRate = new AddExchangeRate(exchangeRateRepository, exchangeRateDateValidator);
addExchangeRateRequestAdapter = new AddExchangeRateRequestAdapter();
getExchangeRate = new GetExchangeRate(exchangeRateView);
getExchangeRateRequestAdapter = new GetExchangeRateRequestAdapter();
}
@PostMapping
@ResponseStatus(HttpStatus.CREATED)
public void create(@RequestBody AddExchangeRateRequest addExchangeRateRequest) {
addExchangeRate.execute(addExchangeRateRequestAdapter.toCommand(addExchangeRateRequest));
}
}
测试:
@RunWith(SpringRunner.class)@WebMvcTest(ExchangeRateStoreController.class)
public class ExchangeRateStoreControllerTest {
@Autowired
private MockMvc mvc;
@MockBean
ExchangeRateRepository exchangeRateRepository;
@MockBean
ExchangeRateDateValidator exchangeRateDateValidator;
@MockBean
ExchangeRateView exchangeRateView;
@Test
public void givenValidExchangeRateCommand_whenCreate_thenOK() throws Exception {
String validRequestBody = "{\"from\":\"EUR\",\"to\":\"USD\",\"amount\":1.2345,\"date\":\"2018-11-19\"}";
doNothing().when(exchangeRateDateValidator).validate(any());
doNothing().when(exchangeRateRepository).save(any());
mvc.perform(post("/").content(validRequestBody).contentType(MediaType.APPLICATION_JSON))
.andExpect(status().isCreated());
}
应用:
@SpringBootApplication@EnableJpaRepositories("com...exchangerate.store.infrastructure.persistence")
@EntityScan("com...exchangerate.store.infrastructure.persistence")
@ComponentScan(basePackages = {"com...exchangerate.store.infrastructure", "com...exchangerate.store.application"} )
public class ExchangeRateStoreApplication {
public static void main(String[] args) {
SpringApplication.run(ExchangeRateStoreApplication.class, args);
}
}
而我在运行测试时得到的错误:
申请开始失败
描述:
组件需要找不到名为’entityManagerFactory’的bean。
行动:
考虑在配置中定义一个名为“ entityManagerFactory”的bean。
但是,正如您所看到的,entityManagerFactory
它不是控制器的依赖项。那么,为什么测试试图加载该bean?我在嘲笑所有的控制器依赖关系,所以我认为它不应该这样做。
回答:
该问题是由于您@EnableJpaRepositories
在应用程序的主类上使用引起的。通过将其放在主类上,表示无论您要测试哪个特定功能段,都必须始终启用JPA存储库。
您可以通过执行以下任一操作来解决问题:
- 移动
@EnableJpaRepositores
并@EntityScan
进入单独的JPA特定的配置类 - 删除
@EnableJpaRepositories
并@EntityScan
依靠自动配置的默认值。为此,您的存储库和实体必须位于主类包的子包中。
Spring Boot的参考文档中对此有更多信息,其中指出以下内容:
如果使用测试注释来测试应用程序的更特定的部分,则应避免在main方法的应用程序类上添加特定于特定区域的配置设置。
在这种特定情况下,特定于特定区域的配置设置为@EnableJpaRepositories
。
