  <p>I have tried going through numerous articles on fixing the issue and even referred the Hibernate documentation on the same. The current code is how Hibernate has mentioned here :</p>
  
  <p><a href="https://docs.jboss.org/hibernate/orm/5.3/userguide/html_single/Hibernate_User_Guide.html#associations" rel="nofollow noreferrer">https://docs.jboss.org/hibernate/orm/5.3/userguide/html_single/Hibernate_User_Guide.html#associations</a></p>
  
  <p>What am I missing here? Help would be appreciated.</p>
