java - 在 micronaut 中为集成测试配置数据库

Question

我正在尝试在 micronaut 中编写集成测试。

我有一个 Controller 类:

@Controller("/hello")
public class HelloController {

    @Inject
    private HelloRepository helloRepository;

    @Get("/")
    public HttpResponse get() {
        return HttpResponse.ok(helloRepository.findAll());
    }
}

我正在尝试为它编写一个集成测试，例如:

@MicronautTest
public class HelloControllerSpec {

    @Inject
    EmbeddedServer embeddedServer;

   @BeforeEach
    void setUp() {
        initMocks(this);
    }

    @Test
    public void testIndex() throws Exception {
        try(RxHttpClient client = embeddedServer.getApplicationContext().createBean(RxHttpClient.class, embeddedServer.getURL())) {
           client.toBlocking().exchange("/hello").status();
        }
    }
}

但我不断收到错误消息:

 No backing RepositoryOperations configured for repository. Check your configuration and try again  

我放在“src/test/java/resources/”下的 application.yml 文件具有以下数据源实现:

datasources:
   default:
      url: jdbc:h2:mem:devDb
      driverClassName: org.h2.Driver
      username: sa
      password: 'sa'
      schema-generate: CREATE_DROP
      dialect: H2
jpa:
   default:
      packages-to-scan:
         - 'com.myproject.project'
      properties:
         hibernate:
            hbm2ddl:
               auto: update
            show_sql: true

我也将它包含在我的 build.gradle 文件中

runtime 'com.h2database:h2'

有没有办法解决这个问题？

编辑:这是我的存储库类

@Repository
public interface HelloRepository extends CrudRepository<BufferConditionEntity, Long> {}

Answer 1

Is there any way to solve this?

是的。

如何做到这一点的细节将取决于对您的项目的更多了解。
您没有显示足够的信息来了解问题所在，因此我将您的代码粘贴到一个项目中，该项目显示您问题中的代码似乎有效。唯一不清楚的是您的 initMocks方法。

micronaut:
  application:

datasources:
  default:

    driverClassName: org.h2.Driver

那个测试通过了。
