title: Should I close connection when using SessionFactoryUtils
body: <p>If I want to use SessionFactoryUtils to get Connection directly to execute some SQL statement, and join the same transaction.
  Like this:</p>
  
  <pre><code>SessionFactoryUtils.getDataSource(getSessionFactory()).getConnection();
  //some logic after Connection retrieved
  </code></pre>
  
  <p>Do I have to close Connection by myself? or just let it be and Hibernate Session will handle it for me?</p>
