似乎@WebMvcTest
和@MockBean
无法正常工作。也许我丢失了一些东西……我有一个带有一些依赖关系的控制器,正在使用@MockBean
进行模拟,但是该应用程序无法启动,因为它找不到在这种情况下我不需要的另一个bean。
控制器:
@RestController
public 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);
}
}
以及运行测试时出现的错误:
申请无法开始
说明:
一个组件需要一个名为“ entityManagerFactory”的bean,该bean可以 找不到。
操作:
考虑在您的计算机中定义一个名为“ entityManagerFactory”的bean 配置。
但是,正如您所看到的,entityManagerFactory
不是控制器的依赖项。那么,为什么测试试图加载该bean?我正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。

问题是由您在应用程序的主类上使用@EnableJpaRepositories
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,都必须始终启用JPA存储库。
您可以通过以下方法之一解决问题:
@EnableJpaRepositores
和@EntityScan
移动到单独的JPA特定的配置类上@EnableJpaRepositories
和@EntityScan
并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reference documentation中有关于此的更多信息,其中显示以下内容:
如果您使用测试注释来测试应用程序的特定部分,则应避免在主方法的应用程序类中添加特定于特定区域的配置设置。
在这种情况下,特定于特定区域的配置设置为@EnableJpaRepositories
。

你好,这篇文章有一个很好的链接:EntityManagerFactory not found in SpringBoot
您可以检查您的spring boot jpa集成,并有一些很好的技巧来设置您的环境。
