使用Micronaut-test模拟CrudRepository的Micronaut-data

Question

我尝试为API控制器编写UnitTest，它使用来自micronaut-data-jpa的CrudRepository。我使用@mockbean来模拟控制器中的协作存储库。如果我运行测试，我会得到以下错误：

消息：bean[jens.repositories.connectionProfileRepository]没有这样的方法[findById(java.lang.object)]

我从未使用过Spock、Micronaut-Data或Micronaut-Test，只从以下来源尝试过：

https://micronaut-projects.github.io/micronaut-test/latew/guide/index.html

控制器：

ConnectionProfileRepository profileRepository

    ProfilesController(ConnectionProfileRepository profileRepository) {
        this.profileRepository = profileRepository
    }

语言：Groovy存储库

interface ConnectionProfileRepository extends CrudRepository<ConnectionProfile, UUID> { }

测试

@MicronautTest
class ProfilesControllerSpec extends Specification {

    @Inject
    ConnectionProfileRepository profilesRepositoryMock

    @MockBean(ConnectionProfileRepository.class)
    ConnectionProfileRepository profileRepository() {
        Mock(ConnectionProfileRepository)
    }
...

我如何用我的当前设置来管理在我的控制器中实现存储库的模拟？
