Question

我想使用mongo-java-driver 3.2.2连接到我的secondary-mongo节点，如下所示（我在私人网络中）

object Database {

  //val uri = new MongoClientURI("mongodb://staging-node3.shaharma.com") 
  val seeds = new ServerAddress("staging-node3.shaharma.com")
  val credentials : MongoCredential = MongoCredential.createScramSha1Credential(
       "userId", "events", "userP@ssword".toCharArray)
   val options = new MongoClientOptions.Builder().readPreference(ReadPreference.secondary()).build()
}



def something()  = {
      val connection = new MongoClient(Database.seeds, asList(Database.credentials), Database.options)

      println("read-preference : " + connection.getReadPreference) //secondary
      println("read-preference slaveOk: " + connection.getReadPreference.isSlaveOk) //true

      val db: MongoDatabase = connection.getDatabase("events")
      val logs = db.getCollection("MessageEvents")
      val events = messageLog.distinct("event", classOf[String]).iterator()

      //
}

但我不断收到以下Exception authenticating MongoCredential错误：

play.api.http.HttpErrorHandlerExceptions$$anon$1: Execution exception[[MongoTimeoutException: Timed out after 30000 ms while waiting for a server that matches ReadPreferenceServerSelector{readPreference=secondary}.

我可以使用mongo命令行

成功连接到服务器

mongo --host staging-node3.shaharma.com --username userId --password userP@ssword --authenticationDatabase events
rs.slaveOk(true)

我使用scram-sha-1进行身份验证。

您可以尝试使用MongoCredential.createCredential()代替MongoCredential.createScramSha1Credential并检查是否有效吗？

MongoDB＆＃34;异常验证MongoCredential＆＃34;使用java-driver
