java 引入mongoclient 为啥报错呢?

package com.company;
import com.mongodb.client.MongoClient;
public class Mongo {
    String ip="106.12.79.168";
    int port=27017;
    MongoClient mongoClient = new MongoClient("localhost", 27017);
    public Mongo(String ip, int port){
       this.ip=ip;
       this.port=port;
   }
}

你mongodb的引入的maven是什么版本呢,贴出来看看,是不是高版本使用方式改了

我用的这个版本,可以直接new ,不是抽象类

<dependency>
 <groupId>org.mongodb</groupId>
 <artifactId>mongodb-driver</artifactId>
 <version>3.8.2</version>
</dependency>
