Neo4j - ошибка аутентификации Java

Question

Я новичок в Java и neo4j.Попытка моего первого подключения к neo4j с помощью приложения JavaЯ не могу понять, почему я получаю сообщение об ошибке: Exception in thread "main" org.neo4j.driver.v1.exceptions.AuthenticationException: The client is unauthorized due to authentication failure.

• Болт: болт: // localhost: 7687 (рабочий стол neo4j на моем macbook)
• GraphName: PrakashTest1
• Пароль: 12345678

Java-приложение:

import org.neo4j.driver.v1.AuthTokens;
import org.neo4j.driver.v1.Driver;
import org.neo4j.driver.v1.GraphDatabase;
import org.neo4j.driver.v1.Session;
import org.neo4j.driver.v1.StatementResult;
import org.neo4j.driver.v1.Transaction;
import org.neo4j.driver.v1.TransactionWork;

import static org.neo4j.driver.v1.Values.parameters;

public class HelloWorldExample implements AutoCloseable {

  private final Driver driver;

  public HelloWorldExample( String uri, String user, String password ) 
  {
      driver = GraphDatabase.driver( uri, AuthTokens.basic( user, password ) );
  }

  @Override
  public void close() throws Exception 
  {
      driver.close();
  }

  public void printGreeting( final String message ) {
      try ( Session session = driver.session() )
      {
          String greeting = session.writeTransaction( new TransactionWork<String>()
          {
              @Override
              public String execute( Transaction tx )
              {
                  StatementResult result = tx.run( "CREATE (a:Greeting) " +
                                                    "SET a.message = $message " +
                                                    "RETURN a.message + ', from node ' + id(a)",
                          parameters( "message", message ) );
                  return result.single().get( 0 ).asString();
              }
          } );
          System.out.println( greeting );
      }
  }

  public static void main( String... args ) throws Exception
  {
      try ( HelloWorldExample greeter = new HelloWorldExample( "bolt://localhost:7687", "PrakashTest1", "12345678" ) )
      {
          greeter.printGreeting( "hello, world" );
      }
  }
