At the end of this guide, you will have created a simple Java console Hello, World! program that connects to the Memgraph database and executes simple queries.


For this guide you will need:

  • A running Memgraph instance. If you need to setup Memgraph, take a look at the Installation guide.

  • A basic understanding of graph databases and the property graph model.

  • Java 8 or 11 installed.

Basic Setup

We'll be using Eclipse IDE 2020-09 on Windows 10 to connect a simple Java console application to a running Memgraph instance using Maven. If you're using a different IDE, the steps might be slightly different, but the code is probably the same or very similar.

Let's jump in and connect a simple program to Memgraph.

1. Open Eclipse and create a new Maven project. 2. Select the Create a simple project option. 3. For the Group Id field put and for Artifact Id put my-app. Afterwards, click the Finish button. 4. Open the pom.xml file and add the following dependency:


5. Create the program and copy the following code:

import org.neo4j.driver.AuthTokens;
import org.neo4j.driver.Driver;
import org.neo4j.driver.GraphDatabase;
import org.neo4j.driver.Session;
import org.neo4j.driver.Result;
import org.neo4j.driver.Transaction;
import org.neo4j.driver.TransactionWork;
import static org.neo4j.driver.Values.parameters;
public class HelloWorld implements AutoCloseable
private final Driver driver;
public HelloWorld( String uri, String user, String password )
driver = GraphDatabase.driver( uri, AuthTokens.basic( user, password ) );
public void close() throws Exception
public void printGreeting( final String message )
try ( Session session = driver.session() )
String greeting = session.writeTransaction( new TransactionWork<String>()
public String execute( Transaction tx )
Result result = "CREATE (a:Greeting) " +
"SET a.message = $message " +
"RETURN 'Node ' + id(a) + ': ' + a.message",
parameters( "message", message ) );
return result.single().get( 0 ).asString();
} );
System.out.println( greeting );
public static void main( String... args ) throws Exception
try ( HelloWorld greeter = new HelloWorld( "bolt://localhost:7687", "", "" ) )
greeter.printGreeting( "Hello, World!" );

Once you run the program, you should see an output similar to the following:

Node 1: Hello, World!
