我正在尝试使用Guice创建一个通用特征的绑定

看看如何trait定义

trait Repository[T]

查看trait实施

class DomainRepository extends Repository[Domain]

我的配置方法DomainPersistenceModule是:

def configure() {
   bind(classOf[Repository[Domain]])
     .annotatedWith(classOf[DomainDependency])
     .to(classOf[DomainRepository])
     .in(Scopes.SINGLETON)
}

将注入依赖关系的变量是:

  @Inject
  @DomainDependency
  var repository:Repository[Domain] = _

注射发生在这里:

val injector:Injector = Guice.createInjector(new PersistenceModule())

val persistenceService:PersistenceService =
        injector.getInstance(classOf[DomainPersistenceService])

错误是:

Caused by: com.google.inject.ConfigurationException: Guice configuration errors:

1) No implementation for repository.Repository<domain.Domain> annotated with @module.annotation.DomainDependency() was bound.
  while locating repository.Repository<domain.Domain> annotated with @module.annotation.DomainDependency()
    for field at service.persistence.DomainPersistenceService.repository(DomainPersistenceService.scala:19)
  while locating service.persistence.DomainPersistenceService

我错过了什么吗？提前致谢
