带有@EnableJpa* 注解的Spring @WebMvcTest

我有下面的主类。

@EnableJpaAuditing
@SpringBootApplication
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class SampleApplication {

    public static void main(String[] args) {
        SpringApplication.run(SampleApplication.class, args);
    }
}

和下面的单元测试类。

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = { AccountController.class }, secure = false)
public class AccountControllerTest {

    @Autowired
    private MockMvc mockMvc;
    // Commented out below

如果我运行单元测试，它会给我这个错误。
非法参数异常：必须至少存在一个JPA元模型!
因此，我进行了研究，发现这是由于在使用@WebMvcTest时将@EnableJpa*注解放置在主类中，它找不到@Entity类，因此出现了错误消息。
我遇到了一个page，并描述了或多或少与我相同的问题，并建议使用@SpringBootTest和@AutoConfigureMockMvc而不是@WebMvcTest。
这是进行测试的唯一方法吗？我希望能够使用@WebMvcTest，因为使用@SpringBootTest会加载完整的上下文，并且需要更长的时间来运行测试。
根据要求纳入测试类别。

@WebMvcTest(controllers = { AccountController.class }, secure = false)
public class AccountControllerTest {

@Autowired
private MockMvc mockMvc;

@MockBean
private AccountService accountService;

@MockBean
private RaceService raceService;

和控制器类。

@Controller
@RequiredArgsConstructor
public class AccountController {

private final AccountService accountService;

@Autowired
private RaceService raceService;

同时启用调试模式。
太长了，所以请看https://pastebin.com/FyUzfN2a
我使用的是Spring 2.0.3-发布版。

spring-boot

将@Enable*注解移动到一个专用的@Configuration类中，这在Sping Boot Reference Guide的特别章节User Configuration and Slicing中也有解释，并在此处注明。
你的主类应该只有@SpringBootApplication注解，然后创建一个带有@Enable注解的类。

@SpringBootApplication
public class SampleApplication {

    public static void main(String[] args) {
        SpringApplication.run(SampleApplication.class, args);
    }
}

以及JPA的特定配置

@Configuration
@EnableJpaAuditing
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class JpaEnversConfiguration {}

现在您可以安全地使用@WebMvcTest，而不会让它抱怨JPA。

我遇到了同样的问题，但我发现给出的建议“将@Enable* 注解移到一个专用的@Configuration类”是不必要的。
在我的应用程序中，我没有配置类。
我只是从主应用程序类中删除了@EnableJpaRepositories.，这样我就可以

@SpringBootApplication
public class EncourageApplication {

我的存储库：

public interface EncouragementRepository extends JpaRepository<Encouragement,Long> {

并且在测试中，
对于控制器：

@ExtendWith(SpringExtension.class)
@WebMvcTest(EncouragerController.class)
class EncouragerControllerTest {

对于存储库：

@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@ExtendWith(SpringExtension.class)
@DataJpaTest
class EncouragementRepositoryTest {

并且对于集成测试，

@SpringBootTest
class EncourageApplicationTests {

希望这能帮到什么人。
