[S2] How to get an object from Spring inside an interceptor
Hi,
I want to implement an OpenInView pattern interceptor involving
Hibernate, but there's a problem. My SessionFactory is both created
and managed by Spring, and my interceptor should have access to that
SessionFactory, however I don't know how to do that. I have already
searched a lot the web and the docs but couldn't find an answer. Does
anybody know if that's possible (and how)?.
Regards,
Célio.

The actions are unaware of any Hibernate type. This is mandatory
since I don't want my actions to depend on a specific persistence
mechanism. They only see DAO interfaces (which are also not dependent
on any persistence mechanism).
Thanks,

if your SessionFactory is injected in your action, and all your
actions extend "AbstractAction" for example, that has a
getSessionFactory() method, you can do this:
public String intercept(ActionInvocation invocation) throws Exception {
Action action = (Action) invocation.getAction();
if (action instanceof AbstractAction) {
sessionFactory = ((AbstractAction) action).getSessionFactory();
...
}

Not the most elegant solution, but you can pull the ApplicationContext
from the ServletContext:
ServletContext sc = ServletActionContext.getServletContext();
(ApplicationContext)sc.getAttribute("org.springframework.web.context.WebApplicationContext.ROOT");
