Question

此问题与我先前在Spring @WebMvcTest with @EnableJpa* annotation上的问题相关。

因此，我将@ Enable *移至@Configuration类，但是这破坏了我的其他单元测试类，这就是为什么我有前面的问题。我想我以前没有很清楚地解释过，所以我尽力做到这一点。

如答案所示，解决以下错误：“至少必须存在一个JPA元模型！”使用@WebMvcTest运行测试时，是将@Enable*注释移至@Configuration类。虽然确实可以解决问题，但其他测试类中还是发生了许多其他问题，我不确定为什么会破坏这些问题。

根据我现在所看到的，它打破了两种类型的测试类。 1.邮件（@SpringBootTest测试类和2.存储库（@DataJpaTest）测试类。

在我继续之前，这些是我认为相关的课程的片段。

主要

@SpringBootApplication
public class SampleApplication {

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

AppConfiguration

@Configuration
@EnableCaching
@EnableJpaAuditing
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfiguration {

}

AccountServiceImpl

@Service
@RequiredArgsConstructor
public class AccountServiceImpl implements AccountService {

    private final AccountRepository accountRepository;
    private final RoleRepository roleRepository;
    private final PasswordEncoder passwordEncoder;
    private final ApplicationEventPublisher applicationEventPublisher;

MailServiceImpl

@Service
@RequiredArgsConstructor
public class MailServiceImpl implements MailService {

    private final JavaMailSender mailSender;
    private final MailTemplateContentBuilderImpl mailTemplateContentBuilder;

邮件（@SpringBootTest）测试类

`

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class MailServiceTest {

    @Autowired
    private MailService mailService;

    private GreenMail smtpServer;

    @Before
    // Removed below

存储库（@DataJpaTest）测试类。

`

@RunWith(SpringRunner.class)
@DataJpaTest
public class AccountRespositoryTest {

    @Autowired
    private TestEntityManager entityManager;

    @Autowired
    private AccountRepository accountRespository;

`

然后出现错误（见https://pastebin.com/WBMccZUu）。（因为包含的时间太长了）

请记住，如果我不打算使用@Configuration类，则不会发生这两种类型的错误。但是，如果我不为@Configuration注释移至@Enable*，那么将发生JPA元模型错误。

<罢工> 我对存储库问题的猜测，看不到@Configuration类？但是，我尝试在/ src / test文件夹中使用@Configuration创建相同的@TestConfiguration类，并在ApplicationConfigurationTest.class中调用。

@TestConfiguration @EnableJpaAuditing @EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class) public class ApplicationConfigurationTest { }

在我的Repository类中，我做了一个@Import(ApplicationConfigurationTest.class)，它也不起作用。但是，它抱怨着另一个性质相同的问题。

要清楚，这就是我所做的。我并不是说我在实际的Repository类上做过。在测试课上。

@TestConfiguration
@Import(ApplicationConfiguration.class)
public class ApplicationConfigurationTest {

}

我也尝试过。

@TestConfiguration
@EnableJpaAuditing
@EnableJpaRepositories(repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfigurationTest {

}

@DataJpaTest
@Import(ApplicationConfigurationTest.class) 
// Tried this as well, doesn't work
// @Import(ApplicationConfiguration.class)
public class AccountRespositoryTest {

    @Autowired
    private TestEntityManager entityManager;

但是它仍然提供与以前相同的NoSuchBeanDefinitionException。

金达一无所知。确保我的测试可以正常运行的正确方法应该是什么。

谢谢。并让我知道是否错过任何信息。

Answer 1

在SpringBootTest中使用 classed = {SampleApplication.class} 因此SampleApplication将帮助创建所有依赖项。

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {SampleApplication.class}, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class MailServiceTest {

    @Autowired
    private MailService mailService;

    private GreenMail smtpServer;

    }

Answer 2

我认为我已经设法解决了我的问题，实际上我以前与 @M确实非常接近。 Deinum 评论。

实际上很简单。

如前所述，我创建了一个@TestConfiguration。但是我错过了使用basePackages的机会，或者我错误地使用了它。因此，我在阅读spring-data query method documentation时遇到了这一部分：

此外，请注意，JavaConfig变体未配置程序包明确地，因为带注释的类的包由默认。 要自定义要扫描的软件包，请使用basePackage之一。特定于数据存储的存储库的属性 @ Enable $ {store}存储库注释。

这就是我的所在。因此，我在@TestConfiguration的 basePackages 中进行了扫描，我认为这是因为我的测试位于不同的程序包中，而当您执行@DataJpaTest时，它不会t从其他软件包中提取类（如果我错了，请纠正我）。

然后，如果您看到Spring Auto-configured Tests Documentation，它也会指出（我知道）：

通常仅有助于加载配置的以下部分：需要测试您的应用程序的“切片”。例如，您可能想要测试Spring MVC控制器是否正确映射了URL，并且您不想在这些测试中涉及数据库调用，或者您可能想测试JPA实体，而您对网络不感兴趣这些测试运行时层。

因此，使用@DataJpaTest，您需要特别@import @TestConfiguration。

@TestConfiguration
@EnableJpaAuditing
@EnableJpaRepositories(basePackages = "com.sample", repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class)
public class ApplicationConfigurationTest {

}

@DataJpaTest
@Import(ApplicationConfigurationTest.class) 
public class AccountRespositoryTest {

    @Autowired
    private TestEntityManager entityManager;

而且我怀疑，这也解决了我也面临的 MailServiceTest类问题。

这是一个很好的经验教训，值得更认真地阅读文档。

使用@Configuration时运行单元测试时出现NoSuchBeanDefinitionException
