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?

Answer 1

You most likely will need to create a HttpSessionListener.

Answer 2

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.
