Micronaut-data 使用 Micronaut-test 模拟 CrudRepository

Question

我尝试为我的 API 控制器编写 UnitTest，该控制器使用 micronaut-data-jpa 中的 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，则会出现以下错误：

Message: No such method [findById(java.lang.Object) ] for bean [jens.repositories.ConnectionProfileRepository]

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

https://micronaut-projects.github.io/micronaut-test/latest/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)
    }
...

如何使用当前的设置来实现控制器中存储库的模拟？
