JDBC接続を作成できません[jdbc：postgres：// localhost：5432/hibernatedb]

Question

データベースを使用してソフトウェアを作成しようとしていますが、多くの試行後にtutorial on youtubeに従っています。

私は、Java 8、PostgreSQL 9.4、およびHibernate 5.2.2（およびJBoss Tools 4.4.1）を使用しています。

は、私がアプリケーションを実行するまでのチュートリアルに従ったが、その後、次のエラーメッセージは、アプリケーションがデータベースに接続できないことを言って、表示されます。

接続文字列は

<property name="hibernate.connection.url">jdbc:postgres://localhost:5432/hibernatedb</property> 

から接続URL値、変更しようとして

<property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/hibernatedb</property>
