Re: [appfuse-user] Database driven struts menu and filter

[Jonathan Tse]

Matt,

   Thanks for your pointer. I am not familiar with 
HttpSessionActivationListener so i write one filter to test it. I notice 
that contextInitialized is called. I expected that sessionDidActivate() 
method will be called when there is a request from a client. However, it 
is not what i expected so I cannot stuff the menu to the session. Any idea?

Best regards,
Jonathan

p.s. : Attached please find the code of this test filter

public class TestListener implements  ServletContextListener, 
HttpSessionActivationListener {
   private final transient Log log = LogFactory.getLog(TestListener.class);
   private transient ServletContext servletContext;


   public synchronized void contextInitialized(ServletContextEvent sce) {
       log.debug("test listenereerqewr initialized");
       servletContext = sce.getServletContext();

       try {
           ApplicationContext ctx =
               
WebApplicationContextUtils.getWebApplicationContext(servletContext);
           if (ctx != null) {
           }
       } catch (NoSuchBeanDefinitionException n) {
           // ignore, should only happen when testing
       }

   }

   public synchronized void contextDestroyed(ServletContextEvent event) {
       servletContext = null;
   }

   public void sessionWillPassivate(HttpSessionEvent se) {
       log.debug("test 2");
   }

   public void sessionDidActivate(HttpSessionEvent se) {
       log.debug("test 1");
   }
}

You could use an HttpSessionActivationListener and do it that way -
stuff the menu repository in the session of each new user.

Hi all,

    I am using Spring 1.9.4 and Spring MVC. I want to make a strut menu
from database. According to the Database Driven Menu example, it
suggests using filter to preload the data to the menu repository. I have
written my data loading logic in service manager already, so how i can
inject the service manager to this filter?

    Please help. Thanks.

Best regards,
Jonathan
