Question

我使用“ net start mongidb”以管理模式成功启动了MongoDB服务器。

我正在用Kotlin作为语言在Android Studio中工作。我添加了库mongo-java-driver-3.11.0-rc0.jar并导入：

import com.mongodb.MongoClient
import com.mongodb.MongoException
import com.mongodb.BasicDBObject

并编写了一个简单的kotlin脚本：

val mongo = MongoClient("localhost", 27017);

运行此命令时，出现此错误（在日志中显示权限被拒绝，而我在admin模式下同时运行mongodb和android studio）：

    I/cluster: Cluster created with settings {hosts=[localhost:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500}
    I/cluster: Exception in monitor thread while connecting to server localhost:27017

如何在Kotlin中解决MongoDB的套接字连接问题？
