Is there a "Spring 3 MVC way" to listen to the end session event?

Question

I would like to delete some temporal files when user session finishes. The information associated with the files is stored in an object annotated with @SessionAttributes.

The only way I've found to deal with this is creating an HttpSessionListener.

Is there a higher level, simplified, Springy way to listen to the session end event where I could easily get my annotated object?

If the user logs out, you can act on that event. If the user just wanders off, `HttpSessionListener` is the only option. — DwB, Mar 06 '12 at 20:43

You most likely will need to create a HttpSessionListener.

Two options to use HttpSessionListener with spring beans:

The first is to use WebApplicationContextUtils.getRequiredApplicationContext(servletContext) to obtain the servlet context. From there you have two sub-options:

use getBean(..)
If you want to use @Autowired / @Inject use getAutowireCapablyBeanFactory().autowireBean(this). You will have to do this only once (check if the fields are null), because the listener is singleton.

The second option is to use AspectJ and @Configurable on the listener.

I've been researching this topic for awhile. Do you know where I can find a complete example of this. Thanks in advance – stackoverflow Dec 10 '13 at 17:17
I don't know, but I think the above snippets should be sufficient :) – Bozho Dec 12 '13 at 12:44

Not directly related, but might be an interesting project to look at.

https://github.com/shawnmclean/Idle.js

Session deletion typically happens on the server side, when the session expires (usually 30mn). The project above allows to detect user behaviors in the front end.
