<p>My <code>HibernateConfiguration.java</code> file is:</p>

<p>And <code>application.properties</code> is:</p>

<pre><code>jdbc.driverClassName= com.mysql.jdbc.Driver
jdbc.url= jdbc:mysql://localhost:3306/hrm?createDatabaseIfNotExist=true
jdbc.username= user

hibernate.dialect= org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql= true 
hibernate.format_sql= true
hibernate.hbm2ddl.auto=update

<p>What am I missing here?</p>
