[Hibernate-devel] Re: mvc & lazy loading

[Colin E. <ce...@mo...>]

Hi Brad,

I haven't tried this yet, but if I wanted to use lazy loading with Struts, I
would probably override ActionServlet and do something like this, and have
my DAO layer pull the session from the request context as needed:

----
/**
 * Hibernate Action Servlet
 */
public class HibernateActionServlet
        extends ActionServlet
{
    public void service(HttpServletRequest request, 
                        HttpServletResponse response)
    {
        Session session = null;
        try
        {
            session = factory.openSession();
            request.setAttribute("session", session);
            super.service(request, response);
        }
        finally
        {
           if(session != null) session.close();
        }
    }
}
----

Do other frameworks allow the controller servlet to be overridden?  This
probably is a fairly straightforward way to get lazy loading working.
