迁移到 Play 2.5 后,ReactiveMongo ConnectionNotInitialized In Test

ReactiveMongo ConnectionNotInitialized In Test After Migrating to Play 2.5

将我的 Play (Scala) 应用程序迁移到 2.5.3 后,使用 ReactiveMongo 对我的代码进行的一些测试曾经通过,但现在在设置中失败了。

这是我使用 ScalaTest 的代码:

def fixture(testMethod: (...) => Any) {
      implicit val injector = new ScaldiApplicationBuilder()
        .prependModule(new ReactiveMongoModule)
        .prependModule(new TestModule)
        .buildInj()          
      def reactiveMongoApi = inject[ReactiveMongoApi]
      def collection: BSONCollection = reactiveMongoApi.db.collection[BSONCollection](testCollection)
      lazy val id = BSONObjectID.generate
      //Error occurs at next line
      Await.result(collection.insert(Person(id = id, slug = "test-slug", firstName = "Mickey", lastName = "Mouse")), 10.seconds)
...
}

在插入行,我得到这个:

reactivemongo.core.errors.ConnectionNotInitialized: MongoError['Connection is missing metadata (like protocol version, etc.) The connection pool is probably being initialized.']

我尝试了很多方法,比如用 lazy val 而不是 def 来初始化 collection。但是没有任何效果。

任何关于如何使我的测试再次通过的见解都将受到赞赏。

感谢@cchantep,通过替换上面的代码,测试按预期运行:

def collection: BSONCollection = reactiveMongoApi.db.collection[BSONCollection](testCollection)

使用此代码

def collection: BSONCollection = Await.result(reactiveMongoApi.database.map(_.collection[BSONCollection](testCollection)), 10.seconds)

换句话说,reactiveMongoApi.database(以及由于 Future 而进行的适当更改)是要走的路。
