MongoDB Learning (ii) Java connection

The last chapter is over MongoDB installation and IDE tools, now start using Java to connect.

The first step: using the jar package,

Here need three packages, specifically why I do not know, anyway, because of the error, I have to follow the official documents are downloaded.

D:\jar\mongodb\bson-3.5.0.jar
D:\jar\mongodb\mongodb-driver-core-3.5.0.jar
D:\jar\mongodb\mongodb-driver-3.5.0.jar

The second step is the code:

Import Com.mongodb.mongoclient;import com.mongodb.client.mongodatabase;/** * @author  szy  * @version Created on: 2018-3-31 pm 9:48:59 *  */public class Mongodbtest {/** * @param args */public static void main (string[] args) {// TODO auto-generated method Stubmongoclient mongoclient = new Mongoclient ("localhost", 27017); Mongodatabase mgdb = mongoclient.getdatabase ("test"); System.out.println ("Connect to Database successfully!");        System.out.println ("Mongodatabase inof is:" +mgdb.getname ());}}

The output is:

Connect to Database successfully! Mongodatabase inof Is:test

Ok. Test the connection successfully.
