使用kotlin语言连接mongodb服务进行添加数据操作

package com.xctl.util

import com.mongodb.MongoClient
import com.mongodb.MongoCredential
import com.mongodb.ServerAddress
import org.bson.Document
import java.util.*

object MongoDBJDBCandUsernameAndpassword {
    @JvmStatic
    fun main(args: Array<String>) {
        try {
            //连接到MongoDB服务 如果是远程连接可以替换“localhost”为服务器所在IP地址
            //ServerAddress()两个参数分别为 服务器地址 和 端口
            val serverAddress = ServerAddress("39.106.196.5", 27017)
            val addrs = ArrayList<ServerAddress>()
            addrs.add(serverAddress)

            //MongoCredential.createScramSha1Credential()三个参数分别为 用户名 数据库名称 密码
            val credential = MongoCredential.createScramSha1Credential("house_keeper", "house_keeper", "house_keeper".toCharArray())
            val credentials = ArrayList<MongoCredential>()
            credentials.add(credential)

            //通过连接认证获取MongoDB连接
            val mongoClient = MongoClient(addrs, credentials)

            //连接到数据库
            val mongoDatabase = mongoClient.getDatabase("house_keeper")
            val collection=mongoDatabase.getCollection("HotelRoomInformation")
            val document = Document("title", "MongoDB").append("description", "database").append("likes", 100).append("by", "Fly")
            val documents = ArrayList<Document>()
            documents.add(document)
            collection.insertMany(documents)
        } catch (e: Exception) {
            System.err.println(e.javaClass.name + ": " + e.message)
        }

    }

}

//在mongodb的可视化工具显示如下结果
