在我的Module.scala
中,我绑定了如下特质的具体实现:
trait AccessGroupRepository[F[_]] {}
@Singleton
class AccessGroupRepositoryImpl @Inject()(db: OldDataBase, c: IOContextShift)
extends AccessGroupRepository[IO] {}
并使用TypeLiteral
完成绑定:
bind(new TypeLiteral[AccessGroupRepository[IO]] {}).to(classOf[AccessGroupRepositoryImpl])
现在,在使用Mockito模拟进行测试时,我需要覆盖此绑定:
override val application: Application = guiceApplicationBuilder
.overrides(bind(new TypeLiteral[AccessGroupRepository[IO]] {}).to(agRepoMock))
但出现以下错误:
overloaded method value bind with alternatives:
[error] [T](implicit evidence$1: scala.reflect.ClassTag[T])play.api.inject.BindingKey[T] <and>
[error] [T](clazz: Class[T])play.api.inject.BindingKey[T]
[error] cannot be applied to (com.google.inject.TypeLiteral[api.v1.accessgroup.AccessGroupRepository[cats.effect.IO]])
[error] .overrides(bind(repoTypeLiteral).to(agRepoMock))
[error] ^
我该如何解决?
