Where to store request specific values in Spring MVC?

I'm using Spring MVC and I want to store request specific values somewhere so that they can be fetched throughout my request context. Say I want to set a value into the context in my Controller (or some sort of handler) and then fetch that value from some other part of the Spring request/response cycle (could be a view, view resolver, interceptor, exception handler, etc)... how would I do that?

My question is:

Does Spring MVC already provide a method to do what I described above?
If Spring doesn't have this functionality, any ideas on the best way to do this (by extending something maybe)?

Thanks!

You could use sessionAttributes.

Session Attributes

I took the latest version of the api (3.1) since you didn't mention your version of spring.

If you need to pass an object from your controller to view, you can use Spring's ModelMap. 

@RequestMapping("/list")
    public String list(ModelMap modelMap) {
            // ... do foo

             modelMap.addAttribute("greeting", "hello");

        return viewName;
    }

on your view:

   <h1>${greeting}</h1>
