mongodb - Mongo Scala Play - java.lang.NoSuchMethodError : com. mongodb.ConnectionString.getApplicationName()Ljava/lang/String;]

Question

我正在尝试在 scala play mongo 原型(prototype)上进行基本的 CRUD。该代码作为独立的主方法工作 - 但当作为通过 Controller 调用的 Play 应用程序执行时，会出现运行时异常

[debug] Running task... Cancel: Null, check cycles: false, forcegc: true
[info] play.api.Play - Application started (Dev)
[error] application - 

! @7b9n058gm - Internal server error, for (GET) [/mongoTestUserCollection] ->

我尝试更改驱动程序版本 - 但出现同样的错误

构建.sbt:

scalaVersion := "2.11.8"
  "org.mongodb.scala" %% "mongo-scala-driver" % "2.3.0",
  "org.mongodb.scala" %% "mongo-scala-bson" % "2.3.0",

连接器:

  val mongoClient: MongoClient = MongoClient("mongodb://server-internal.com:27017/")
  val codecRegistry = fromRegistries(fromProviders(classOf[HistoryRecord]), DEFAULT_CODEC_REGISTRY )
  val database = mongoClient.getDatabase("db-test").withCodecRegistry(codecRegistry)

如果我按如下方式调用该代码，则该代码将起作用:

object MongoService {
  def makeMongoCalls(repo: Repo) = {
    repo.insertHistoryRecords(5)
  }

  def main(args: Array[String]): Unit = {
    makeMongoCalls(UserSessionHistory2MongoDBCollection)
  }
}

Answer 1

Caused by: java.lang.NoSuchMethodError: com.mongodb.ConnectionString.getApplicationName()Ljava/lang/String;

这种情况经常发生在库冲突的情况下。

1. 运行sbt clean
2. 检查依赖项中是否没有其他 MongoDB 驱动程序。一些可以使用它的库。
3. 尝试从依赖项中删除 "org.mongodb.scala"%% "mongo-scala-bson"% "2.3.0"。 "org.mongodb.scala"%% "mongo-scala-driver"% "2.3.0" 已经有了。
