在斯派蒂，有可能 implicit inj: Injector 对于班级和 Injector 在I中定义时，在没有任何附加代码的情况下传递 Module ```
class MessageService(implicit inj: Injector)
extends Injectable {

val officialGreeting =
inject [String] (identified by "greeting.official")

def getGreetMessage(name: String) =
s"$officialGreeting, $name!"
}

//Module
class UserModule extends Module {
bind [MessageService] to new MessageService

binding identifiedBy "greeting.official" to "Welcome"
}

如何做到同样，但在一个特质？

class MessageService() {

val officialGreeting =
inject [String] (identified by "greeting.official")

def getGreetMessage(name: String) =
s"$officialGreeting, $name!"
}

trait MessageServiceReportingMixin extends MessageService with Injectable {

implicit val inj: Injector

val reporter = inject[Reporter]

override def getGreetMessage(name: String) = reporter.report(super.getGreetMessage(name))
}

//Module
class UserModule extends Module {

//I WANT TO AVOID THIS
bind [MessageService] to new MessageService() with MessageServiceReportingMixin {
val inj = injector
}

//I WANT TO DO THIS INSTEAD
bind [MessageService] to new MessageService() with MessageServiceReportingMixin

binding identifiedBy "greeting.official" to "Welcome"
}

有什么问题吗 `implicit val inj: Injector = implicitly` 为了让这个工作？另外，请评论一下将报告从初级课程中分离出来的整体风格
