@ EnableJpa *アノテーション付きのSpring @WebMvcTest

以下のメインクラスがあります。

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

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

そして次のユニットテストクラス。

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

    @Autowired
    private MockMvc mockMvc;
    // Commented out below

単体テストを実行すると、このエラーが発生します。

IllegalArgumentException：少なくとも1つのJPAメタモデルが存在する必要があります！

調査したところ、@EnableJpa*を使用しているときに@WebMvcTestアノテーションがメインクラスに配置されているため、@Entityクラスが見つからないため、エラーメッセージが表示されます。

ページ に遭遇し、多かれ少なかれ同じ問題について説明しました。@SpringBootTestではなく@AutoConfigureMockMvcと@WebMvcTestを使用することをお勧めしました。

これはそれを行う唯一の方法ですか？ @WebMvcTestを使用すると、コンテキスト全体が読み込まれ、テストの実行に時間がかかるため、@SpringBootTestを使用できるようにしたいと思います。

要求に応じてテストクラスを含めます。

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

@Autowired
private MockMvc mockMvc;

@MockBean
private AccountService accountService;

@MockBean
private RaceService raceService;

そしてコントローラクラス。

@Controller
@RequiredArgsConstructor
public class AccountController {

private final AccountService accountService;

@Autowired
private RaceService raceService;

@Enable*アノテーションを専用の@Configurationクラスに移動します。これについては、Spring Boot Reference Guideの特別なセクション ser Configuration and Slicing で説明されており、 here と記されています。

メインクラスには@SpringBootApplicationアノテーションのみを含める必要があります。次に、@Configurationを含む特定の@Enable注釈付きクラスを作成します。

@SpringBootApplication
public class SampleApplication {

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

そして、JPAの特定の構成

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

これで、JPAについて文句を言わずに@WebMvcTestを安全に使用できます。
