Routing 如何使用喷洒路由测试自定义Json对象

我正在为一些CRUD操作创建一个RESTAPI,在mongodb的顶部使用spray路由,这一切都很好,只要我尝试使用specs2测试它就可以了 以下规格

class RestServiceSpec extends Specification with Specs2RouteTest with RoutingRestService

  // database initialization removed for clarity

  "The rest service" should
    "have a player called 'Theo TestPlayer' in the db" in {
      Get("/api/1.0/player/" + player1._id) ~> restRoute ~> check {
        entityAs[Player] must be equalTo(player1)
      }
    }
  }

// some more specs removed for clarity
}
它将失败,并出现以下错误:

MalformedContent(invalid ObjectId ["51308c134820cf957c4c51ca"],Some(java.lang.IllegalArgumentException: invalid ObjectId ["51308c134820cf957c4c51ca"])) (Specs2Interface.scala:25)
由于对源文件和行号的引用指向一个通用的failTest(msg:String)方法,我不知道在哪里查找

更多信息:

我有一个case类,我使用SalatDAO坚持使用Mongo

case class Player(@Key("_id") _id:ObjectId = new ObjectId(), name:String, email:String, age:Int) {}
其中ObjectId()是封装mongodb ID生成的类 为了通过spray_json对其进行编组,我创建了一些jsonFormats

object MyJsonProtocol {
  implicit val objectIdFormat = new JsonFormat[ObjectId] {
    def write(o:ObjectId) = JsString(o.toString)
    def read(value:JsValue) = new ObjectId(value.toString())
  }
  implicit val PlayerFormat = jsonFormat(Player, "_id", "name", "email", "age")
以及我的路线的相关部分(已删除错误处理和日志):


似乎没有人知道,我将_id从ObjectId()更改为一个字符串,并使用一种帮助方法从新的ObjectId()创建它。在需要时使用字符串

谢谢。我也遇到了同样的问题,通过阅读您的问题和答案,我成功地解决了这个问题:)spray json格式化程序是围绕编写格式化程序的能力构建的,它已经为所有默认类型提供了格式化程序,因此只需要为它不支持的类型提供格式化程序
 implicit object ObjectIdJsonFormat extends JsonFormat[ObjectId] {
    def write(obj: ObjectId): JsValue = JsString(obj.toString)

    def read(json: JsValue): ObjectId = json match {
      case JsString(str) => new ObjectId(str)
      case _ => throw new DeserializationException(" string expected")
    }
  }
 implicit object ObjectIdJsonFormat extends JsonFormat[ObjectId] {
    def write(obj: ObjectId): JsValue = JsString(obj.toString)

    def read(json: JsValue): ObjectId = json match {
      case JsString(str) => new ObjectId(str)
      case _ => throw new DeserializationException(" string expected")
    }
  }
