This does NOT connect to the MongoDB port but rather the SSH port. Once these fields are filled in, click ‘Connect’.įor context, the SSH Tunnel first connects into the server through SSH then connects to the MongoDB server locally. Server login password in the ‘SSH Password’ field.Server login username in the ‘SSH Username’ field.Domain (or IP Address) of the server in the ‘SSH Hostname’ field.If you are connecting to a remote server, under the SSH Tunnel field, select ‘Use Password’. If you are connecting to a MongoDB instance running on the same computer as the one accessing it, then no other fields have to be specified. To connect to a new server, click ‘New Connection’ on the left side of the interface. This way, hostname, port, authentication, and replica set name do not have to be specified. Unless specified, most HarkerDev projects run on the default ports. MongoDB Compass runs as an application on your computer, so once you download it, open it (and move it to the Applications folder if applicable). Using MongoDB Compass Opening MongoDB Compass #Mongodb compass project installThen, install MongoDB Compass on the device you are using to connect. This setup is detailed in our guide on Setting Up a Server. Installing MongoDB Compass MongoDBįirst, make sure that mongodb is installed and running mongod on the device you wish to connect to. #Mongodb compass project how toThis guide will explain how to use MongoDB’s GUI to access the database directly. You can see the collections in the MongoDB Compass UI as well.HarkerDev projects often (if not always) use MongoDB as the main database system. Upon executing the above code, a new collection with name User will get created in our database. ("Collection User created successfully") If we want to create a collection(just like table in relational DB) from our java program, we can do so like this: package com.mongo ĭb.createCollection("User", new BasicDBObject()) The above java code which is used to display list of all the databases is similar to the MySQL command show databases MongoDB: Create a Collection MongoClient.getDatabaseNames().forEach(System.out::println) Once we are able to successfully establish connection using MongoClient, we can use the following code to display all the databases available: // display all the databases If your MongoDB is running in authenticated mode, then you will have to provide the username and password while connecting to the database, like this: // code to connect to the database with authenticationīoolean auth = db.authenticate("username", "password".toCharArray()) Mongo mongo = new Mongo("localhost", 27017) #Mongodb compass project driverNOTE: If you are using an older version of the mongodb java driver which is <= 2.10.0, then you should use the following code with Mongo class to create the connection. When the above mentioned code is executed, following output will be produced on console: ("Database DemoDB connected successfully") MongoClient mongoClient = new MongoClient("localhost", 27017) To find the latest version of the above Mongo Java driver, check the following link.īelow we have a simple Java class with a main() method which uses the MongoClient class to setup connection with MongoDB. So we will be adding Maven dependency like this: Java Code to Make Connection with MongoDBįirst we must add the mongo-java-driver-3.10.0.jar file as a dependency in our Java project. We can connect to the DB using this user interface and then test our queries here. Here, we are making use of MongoDB Compass - a GUI tool for MongoDB for visualizing our query output. Now, we are ready for performing CRUD operations with MongoDB through Java. #Mongodb compass project updateIn this, we will learn how to integrate MongoDB with Java and will explore the basic CRUD (Create, Retrieve, Update and Delete) operations.ĭownload Jar, use mongo-java-driver-3.10.0.jar. ![]()
