Re: best way to detect session termination
Hi,
_userDao shouldn't be null if you annotate it in your applicationContext.xml
and grep it out of the ApplicationContext, e.g.
applicationContext.getBean("sessionDestroyedService");
otherwise spring would have already failed as it was not able to autowire
_userDao.

RE: best way to detect session termination
Ilja,
thanks for your reply. If I create a service class like the one below, my
_userDao object is always null. This _userDao works perfectly in other parts
of my app. Do I need to inject the dao in a special way? I think the
integration into spring is the problem, because I don't know where to place
the corresponding part in the config/xml files. As I said, my knowledge of
spring is limited.
My class looks like this:
@Service
@Transactional
public class SessionDestroyedService
{
@ Autowired
private UserDao _userDao;
public void forceLogout(String sessionId)
{
if (_userDao == null)
System.out.println("SessionDestroyedService.forceLogout(): _userDao is
NULL");
else
{
System.out.println("SessionDestroyedService.forceLogout(): _userDao is
OK");
User user = _userDao.getBySessionId(sessionId);
if (user != null)
{
// do the work here...
}
}
}
}

Re: best way to detect session termination
Hi,
create a service class marked with Annotation @Transactional and manage it
with spring. Calls to this function will have get a session from the spring
context.
Spring will open a session before calling any function on this service and
close the session afterwards.
@Service
@Transactional
public class MyService {
@Autowired
private MyDao dao;
public destroySession(String sessionId) {
myDao.deleteMySessionById(sessionId);
}
}

RE: best way to detect session termination
Vineet,
thanks for the snippet. When I try your code, I get again an error message
saying:
org.hibernate.HibernateException: No Hibernate Session bound to thread, and
configuration does not allow creation of non-transactional one here
So, how can I bind the hibernate session to my thread? Or do I need to change
the configuration?

RE: best way to detect session termination
Vineet, could you please give me a hint or a code snippet how to access that interface? I'm a spring beginner and a little bit lost at the moment. As I said, in my app the dao is injected and when the session is destroyed, the link to hibernate is lost.

Re: best way to detect session termination
quick solution to do by retrieving the bean from spring applicationcontext in your webapplication, it will work but i am not sure how good the solution is .

RE: best way to detect session termination
Vineet, I'm now storing the session id in the user record. But now I have another problem, because hibernate tells me now in sessionDestroy(): org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here I'm using spring to inject my dao. I also tried to use the dao in my HttpSessionListener which is configured in web.xml, but that prevents my app from being started by Tomcat. Next I did was to create a manual created hibernate session, but that raised other problems like a missing hibernate.hbm.xml file and I don't want to configure that manually... Does somebody see another way to access my user data, or am I doing something stupid?

Re: best way to detect session termination
i think i didn't use my words correctly :( with "you can store the sessionid when user logs in" i mean persist user object with sessionid when the user signed in ...

Re: best way to detect session termination
can't you simply do that in webapplication.sessiondestroy(String sessionid), you can store the sessionid when user logs in and on sessiondestroyed ,search the user by this sessionid , and change whatever in user object and then persist it..

RE: best way to detect session termination
I studied the classes HttpSessionBindingListener and AbstractHttpSessionStore as you noted, but I think I'll still have no link between the SessionId from the HTTPSession and my own Session.

Re: best way to detect session termination
You could use a HttpSessionBindingListener like Wicket does internally (see AbstractHttpSessionStore). Or as a hack store references to the session objects in the session listener. That's the easy fix, but doesn't scale if you need session replication (unless maybe you use e.g. Terracotta).

RE: best way to detect session termination
Hi Eelco, thanks for the hint. Now I can detect the end of a session. Unfortunately I can't access my own wicket session in that sessionDestroyed() method in order to get the info about the connected user. I've got ther error message "java.lang.IllegalStateException: you can only locate or create sessions in the context of a request cycle". Do you know how I can achieve this?
