Question

我只是有一个reactivemongo（版本：0.11.9）插入查询，如下所示，

class MongoInsertQuery extends Query {
  val DbName = "events-db"
  val CollectionName = "EventStream"

  val driver = new MongoDriver
  val connection = driver.connection(List("127.0.0.1:27018"))

    def insert() = {
        val db = connection(DbName)
        val collection: BSONCollection = db(CollectionName)
        val futureResult: Future[WriteResult] = collection.insert(BSONDocument("type" -> "Product_Received"))
        futureResult onComplete {
          case Success(s) => println("Success " + s)
          case Failure(e) => {
            println("error " + e.getMessage)
            e.printStackTrace()
          }
        }
      }
}

并不重要，但 Scala Play REST控制器会调用该方法

  def sayBeard = Action { request =>
    new MongoInsertQuery().insert()
    Ok(Json.obj("message" -> "TODO respond writeResult"))
  }

当我呼叫端点时，

$ curl -XGET localhost:9000/sayBeard
{"message":"TODO respond writeResult"}

成功插入mongodb 2.4.14，

precise64(mongod-2.4.14) events-db> db.EventStream.find({})
{
  "_id": ObjectId("5683337120906c127504eb79"),
  "type": "Product_Received"
}

但readAndDeserialize上的Failure错误导致future onComplete错误。

我的目的是在插入Collection之后阅读writeResult上的WriteResult（N，message）。

使用mongo 3.0.6，它甚至找不到mongodb。

虽然，我看到连接登录mongo，

2015-12-30T23:21:57.688-0500 I NETWORK  [initandlisten] connection accepted from 127.0.0.1:51663 #11 (11 connections now open)

Answer 1

所以，问题是reactivemongo 0.11.4支持mongodb 3.0+。然后我不得不更新mongodb主机。

  val driver = new MongoDriver
  val connection = driver.connection(List("127.0.0.1:27017"))

读

java.lang.ArrayIndexOutOfBoundsException on update with mongo 2.4.12 #394

ReactiveMongo 0.11.9 throws连接到mongodb 3.0.4时没有可用的主节点
